An owner-occupier business finding the right commercial premises faces a timing problem that is more common than it might seem. The property is available and the seller wants to move quickly, but the commercial mortgage that would ideally fund the purchase cannot complete within the required window — either because the underwriting and legal process takes longer than the deadline allows, or because the property does not yet meet the criteria a commercial lender would require to proceed. Bridging provides a short-term solution: complete the purchase on the bridging facility, then refinance onto the commercial mortgage once the lender is ready and the property meets their standards. When the transition is planned carefully, this is a controlled and effective sequence. When the transition is not planned carefully, the bridge can run longer than expected and the costs that accumulate make what started as a timing solution into an expensive problem.
This guide explains how the bridging-to-commercial-mortgage strategy works in practice, why commercial mortgages can take longer than anticipated, what a credible transition plan needs to cover, and where timing gaps most commonly arise and how they can be avoided. It is for general informational purposes only and is not financial, legal, or tax advice. The appropriate approach for any specific commercial property transaction should be confirmed with a qualified adviser or broker, as individual lender criteria and property circumstances vary considerably.

What bridging while waiting for a commercial mortgage typically involves
In this context, the commercial mortgage is the intended end point and the bridge is the mechanism for reaching it on a realistic timeline. The bridge provides short-term, property-secured finance to complete the purchase when the commercial mortgage either cannot complete within the required timeframe or cannot yet be arranged because the property does not meet the commercial lender’s criteria. The expectation at the point of taking the bridge is that it will be repaid by the commercial mortgage proceeds once the lender is satisfied with both the property and the borrower’s profile. Bridging loans are a tool for speed and short-term flexibility; the commercial mortgage is the tool for long-term affordability. The transition between these two products is where the strategy either stays controlled or begins to create problems.
What makes this strategy more demanding than it appears is that the commercial mortgage refinance is not automatic. A commercial lender will underwrite the refinance on their own criteria at the time of application, not on the basis of the bridge being in place. That means the property needs to meet their condition and use standards, the business needs to demonstrate affordability for long-term repayments, and the documentation needs to be complete and acceptable. A transition plan that assumes the commercial mortgage will follow without specific milestones being met is not a plan — it is an aspiration. The most important discipline in this strategy is treating the commercial mortgage preparation as a parallel process that begins at or near the same time as the bridge, not as something to address once the purchase has completed.
Why commercial mortgages can take longer than expected
Commercial mortgage transactions involve more moving parts than residential borrowing, and several of those parts are not within the borrower’s direct control. Even when the business is financially strong and the property appears straightforward, the process can be extended by valuation complexity, legal due diligence, and the depth of underwriting that commercial lending typically requires. Understanding why this is the case helps explain why the bridge-to-mortgage transition needs to be planned carefully rather than assumed to be quick once the initial purchase has completed.
Valuation of commercial property is more involved than residential valuation because comparable evidence can be thinner, specialist properties may require specialist valuers, and mixed-use or unusual layouts require more detailed assessment. Legal due diligence on commercial property typically covers title restrictions, rights of way, lease arrangements, planning documentation, and any commercial tenant or occupancy history — all of which take time to review and resolve where issues arise. Underwriting itself is more detailed: commercial lenders assess trading performance, management accounts, bank statements, sector risk, and sometimes business forecasts alongside the property security. Many commercial mortgage offers are also subject to conditions — specific repairs, certifications, tenancy evidence, or planning confirmations — that must be met before funds are released. These are not signs that something has gone wrong; they reflect the thoroughness of commercial lending assessment. The risk arises when a purchase timeline does not accommodate that thoroughness, creating the gap that bridging is used to fill.
The transition plan: what it needs to cover
A credible transition plan answers one central question: what has to be true for the commercial mortgage to repay the bridge, and how will those conditions be met within the bridging term? The answer is almost never just a target date — it is a set of specific milestones, grouped across four practical areas, each of which needs to be addressed in the plan before the bridge is agreed rather than after it is running.
The timeline diagram below illustrates how the two tracks — the bridging period and the commercial mortgage preparation — typically need to run in parallel rather than in sequence. The key insight is that commercial mortgage preparation should begin at or near the point of purchase completion, not at the halfway point of the bridging term.
How a bridge-to-commercial-mortgage transition works
The two scenarios below show what happens when preparation runs in parallel versus in sequence
Timelines are illustrative only. Actual durations for underwriting, valuation, legal work, and property works vary considerably by lender, property type, and individual circumstances.
Property eligibility milestones
Commercial lenders typically require the property to meet specific standards before they will lend against it. For owner-occupied premises, this commonly means the property must be suitable for the intended business use, in acceptable structural and physical condition, insurable, and clear of legal or planning complications that affect security enforceability. Where the property has issues that prevent it from meeting these standards at the point of purchase — condition problems that need remediation, use class questions that need planning confirmation, or title matters that require legal resolution — the bridging period is used to address those issues before the commercial mortgage application progresses to completion.
The critical discipline here is identifying the specific conditions the commercial lender will require before the bridge is agreed, not after it has started running. A plan that says works will be done is not sufficient — a plan that says which works will be done, what they will cost, how long they will take, and how the completed state will be evidenced to the commercial lender is a plan the bridging lender can assess and the commercial lender can underwrite against. Any property readiness milestone that is left vague creates a risk that the bridge runs into its term before the commercial lender’s conditions can be confirmed as met. Our guide to commercial bridging loans versus commercial mortgages covers what commercial lenders require from the property in detail.
Borrower and business affordability milestones
A commercial mortgage lender assessing an owner-occupier application focuses primarily on whether the business can service the long-term debt. This assessment goes considerably beyond a simple check of current profitability. Lenders typically examine how long the business has been trading and whether the trading history is sufficient to demonstrate stability, how the proposed mortgage repayments sit alongside the business’s existing financial commitments, whether the sector the business operates in is treated as higher risk by the lender’s policy, and how income is structured within the business — whether through directors’ drawings, dividends, salary, or a combination — and whether the lender’s affordability model accommodates that structure.
Where a business is strong but has characteristics that some commercial lenders treat cautiously — a relatively short trading history, a sector with known cyclicality, or a complex income structure — early feasibility discussions with the intended commercial lender or a specialist commercial mortgage broker are one of the most valuable steps in the transition planning process. These discussions identify potential affordability objections while there is still time to address them or select a more suitable lender, rather than discovering them when the bridge is approaching maturity and the refinance is urgently needed. A transition plan that has not tested the affordability assumption with a commercial lender is based on an assumption rather than a confirmed position.
Document readiness milestones
Commercial mortgage applications require a substantial documentation pack, and the time needed to assemble that pack is consistently underestimated in bridging-to-mortgage transition plans. The business side of the application typically requires two to three years of full accounts, recent bank statements covering at minimum three to six months, management accounts if the most recent full accounts are more than a few months old, and in some cases business forecasts or projections where the lender wants to assess future as well as historic performance. The property side requires title documentation, planning and use class evidence, any lease or tenancy documentation where relevant, and the valuation report commissioned by the commercial lender’s panel.
The practical implication is that the transition plan needs to include specific points at which the commercial mortgage application will be submitted and when each category of documentation will be ready. A plan that identifies the commercial mortgage as the exit but does not specify when the application will be submitted, or that assumes the accounts will be ready without confirming when they will be prepared and who will prepare them, is relying on momentum that may not materialise within the bridging term. Treating the document assembly as a parallel track — beginning at the point of purchase completion and progressing alongside the property works rather than after them — is consistently the most effective way to keep the commercial mortgage timeline on track.
Buffer and contingency
Almost every commercial property transaction encounters a delay at some point: a valuation query that requires additional evidence, a solicitor raising enquiries that take time to resolve, a contractor overrunning a works programme, or a lender requesting documentation that was not anticipated. A transition plan that has no slack for these predictable complications is a plan that will be put under pressure by the first delay it encounters. Building a realistic time buffer into the bridging term — not as a vague additional cushion but as a planned allowance for the complications that are statistically likely — is one of the most important structural decisions in the strategy.
Equally important is identifying a contingency route before the bridge is agreed rather than after it is running. A contingency route is an alternative path to repayment if the commercial mortgage completion is delayed beyond the bridging term: an extension of the bridge where the lender offers this and the cost is acceptable, an alternative commercial lender if the primary lender cannot complete within the required window, or another refinancing structure that can be arranged more quickly. The contingency does not need to be as attractive as the primary plan; it needs to be credible and available. A transition plan whose only answer to “what happens if the commercial mortgage is delayed?” is “it won’t be” is not a robust plan. Our guide to extensions versus refinancing covers the options available when a bridging term needs to be extended.
The timing gap problem
A timing gap arises when the bridging loan matures — or approaches its maturity date — before the commercial mortgage is ready to complete. The mechanics are straightforward: the bridge has a fixed term, the commercial mortgage preparation takes longer than planned, and the two timelines diverge. This can happen because property works overrun, because the commercial lender’s underwriting takes longer than expected, because documentation takes time to assemble, because legal issues emerge during due diligence, or simply because the commercial mortgage application was started too late in the bridging term. Any of these causes can individually create a timing gap; several occurring simultaneously can create a significant one.
The consequences of a timing gap escalate rapidly with the passage of time. In the early stages, a modest extension of the bridge may be available and affordable. As the gap widens, extension costs increase, the lender may require updated valuations or additional evidence, and the borrower faces the pressure of making decisions under time constraint rather than on merit. In the most acute cases, where extension is not available and the commercial mortgage cannot complete, the borrower may face a forced sale of the premises to repay the bridge — an outcome that is almost always more costly and more disruptive than any delay in the original transition plan. Our guide to the real-world bridging timeline covers what drives completion speed in practice, and our guide to refinancing an existing bridging loan covers the options available when a bridge needs to be extended or replaced.
What a strong transition plan typically includes
The table below summarises the key elements of a transition plan and what each one looks like when it is working properly. The consistent theme across all elements is specificity — a plan based on specific milestones, specific timelines, and specific evidence is more resilient than one based on intentions and assumptions.
| Transition plan element | What it looks like in practice | Why it matters for the timing gap |
|---|---|---|
| Early refinance feasibility | A clear view of likely commercial mortgage appetite and constraints, confirmed with a lender or specialist broker before the bridge is agreed | Identifies problems before the clock starts running rather than during the bridging term |
| Property readiness plan | Costed works, clear planning position, resolution of valuation flags — all aligned to what the commercial lender specifically requires | Reduces the chance the commercial lender pauses at the refinance stage for conditions that were foreseeable |
| Document readiness | Accounts, bank statements, management figures, and property documents identified and being assembled from the point of purchase completion | Prevents delays caused by missing documentation when the application needs to progress quickly |
| Commercial mortgage application timeline | A specific date or milestone trigger for submission, not a general intention to apply at some point during the term | Eliminates the silent months where nothing moves and the bridging term reduces without progress |
| Buffer time | A realistic allowance within the bridging term for valuation, legal, and works delays that are statistically likely | Makes the plan resilient to the predictable complications that almost every commercial transaction encounters |
| Contingency route | A credible alternative path to repayment if the commercial mortgage is delayed — extension, alternative lender, or alternative structure | Prevents last-minute decisions under pressure and reduces the risk of the worst-case outcome |
A transition plan that covers all six elements is not a guarantee of a smooth outcome — commercial property transactions involve variables that cannot all be anticipated. But a plan that is specific and resilient on all six dimensions gives the borrower, the bridging lender, and the commercial mortgage lender the clearest possible basis for managing the transition effectively.
Costs and the cost of extended time
The cost of a bridging-to-commercial-mortgage strategy is not simply the sum of the bridging interest rate and the commercial mortgage arrangement fee. The more significant cost risk is time: each additional month of bridge running beyond the planned term adds interest, potentially triggers extension fees, and in some cases requires updated valuations or additional legal work at the borrower’s expense. On a meaningful commercial loan amount at bridging rates, an additional two or three months of unexpected term can represent a cost that materially changes the economics of the transaction relative to what was modelled at the outset.
Interest structure during the transition
Bridging loans on commercial property are typically available with serviced interest, where monthly interest payments are made throughout the term; retained interest, where a number of months of interest is deducted from the advance at drawdown; or rolled-up interest, where interest accumulates and is repaid alongside the principal at the end of the term. In a bridging-to-commercial-mortgage transition, the choice of interest structure has practical implications for both cashflow during the bridge and the refinancing position at the end of it. Rolled-up interest increases the redemption amount progressively over the term, which means a bridge that runs longer than planned produces a higher redemption figure that the commercial mortgage proceeds need to cover. Where the commercial lender’s maximum loan is calculated as a percentage of property value, a higher redemption figure reduces the available net proceeds after repayment and can affect the affordability calculation for the commercial mortgage itself.
Retained interest provides certainty about the monthly cost during the bridge because no interest payments are required, but it reduces the net advance at drawdown — the funds available for the purchase, works, and other costs are less than the gross loan amount. In a transition where funds are needed both to complete the purchase and to fund property works during the bridging period, understanding the net advance position accurately before committing to the bridge is essential. Our guide to rolled-up, retained, and serviced interest explains the mechanics and trade-offs of each structure in detail.
Net advance and the funds available for the transition
The gross loan amount and the funds that actually arrive for the transaction are different figures. Arrangement fees, valuation costs, legal costs, and any retained interest deductions reduce the net advance — the amount released at drawdown — below the headline loan figure. In a commercial property purchase where the completion sum is fixed, a shortfall between the gross loan and the net advance needs to be funded from elsewhere. Where the transition plan also includes property works funded from the bridging advance, the net advance position affects how much is available for those works and therefore how the property readiness timeline can be structured.
Understanding the net advance at the earliest possible stage — before exchange of contracts rather than at offer stage — allows the transaction to be structured around the actual available funds rather than the headline loan figure. A plan that requires the full gross loan to arrive at completion in order to meet the purchase price and fund the works is a plan that may be disrupted by deductions that were foreseeable. The bridging loan calculator allows illustrative net advance and total cost figures to be modelled across different loan amounts, terms, rates, and fee structures. Our guide to gross versus net borrowing in bridging finance covers the mechanics of how fees and interest structures affect the funds received in detail, and our guide to bridging loan fees explained covers the full cost picture.
Common pitfalls and how to avoid them
The same issues arise repeatedly in bridging-to-commercial-mortgage transitions. They are rarely dramatic at the outset — they become serious because time passes and the options narrow. The four pitfalls below account for the large majority of timing gap problems encountered in practice.
Starting the commercial mortgage process too late
The most consistent source of timing gaps is treating the commercial mortgage as a sequential step that begins after the purchase has completed, rather than as a parallel process that begins at or near the same time. A business that completes the purchase using bridging and then focuses entirely on the property works before turning attention to the commercial mortgage application may find that by the time the property is ready for the commercial lender, the bridging term is already in its final weeks. Commercial underwriting, valuation, and legal work then need to complete under time pressure, which increases the risk of complications having a disproportionate impact.
The practical prevention is to begin commercial mortgage preparation — including feasibility discussions, document assembly, and broker engagement — at the point of purchase completion rather than later. The commercial mortgage application can be formally submitted once the property meets the lender’s eligibility conditions, but the preparation work can and should start before those conditions are fully met. A commercial mortgage application that is ready to submit as soon as the property qualifies will progress faster than one being prepared from scratch at that point.
Underestimating works and compliance timelines
Property works in commercial premises consistently take longer than initially estimated, for a combination of reasons: contractor availability, unexpected complications discovered once works begin, lead times for specialist materials, and the time required for regulatory inspections and certifications. Where the commercial mortgage exit depends on specific works being completed and evidenced to the commercial lender’s satisfaction, every week of works overrun is a week of additional bridging cost and a week less margin in the transition timeline. A works programme built on optimistic assumptions is one of the most common and most avoidable sources of timing pressure in this strategy.
The most useful protection is a works schedule that builds in a realistic contingency allowance — not an allowance for a catastrophic overrun but an allowance for the modest delays that are statistically predictable in any construction or refurbishment programme. Combined with a bridging term that includes buffer time beyond the expected works completion date, a realistic works schedule means that a two or three week overrun does not immediately threaten the transition timeline. Works that are simple in concept but dependent on third-party certifications — electrical, fire safety, structural — should be sequenced carefully, as certification timelines are often less predictable than the works themselves.
Valuation and title surprises
Commercial property valuations and legal due diligence regularly uncover issues that were not apparent at the viewing stage: access rights complications, restrictive covenants limiting use, planning documentation gaps, property condition concerns that require additional specialist reports, or boundary matters that need legal resolution. Each of these findings can pause either the bridging application or the commercial mortgage refinance while the issue is addressed. Where the issue is discovered during the bridging term rather than before the bridge is agreed, the time and cost of resolution comes directly out of the transition window.
Early legal and valuation engagement reduces this risk. Commissioning a solicitor’s review of the title documentation and a preliminary valuation discussion before exchange of contracts can identify the most significant issues while there is still time to address them before the bridge starts running. Not all issues can be identified in advance, but the ones that can be are almost always better discovered early. A transition plan that treats early due diligence as an optional step is one that is more likely to encounter a mid-bridge surprise that disrupts the commercial mortgage timeline.
Relying on a single commercial mortgage route without contingency
Commercial mortgage lenders can change their appetite for specific property types, sectors, or borrower profiles, and what appeared to be a clear route to refinance at the start of the bridge may look less straightforward by the time the application is submitted. A transition plan that depends entirely on one specific lender providing the commercial mortgage, with no alternative route identified, is exposed to that lender’s assessment at the time of application rather than at the time of planning. If the preferred lender declines, raises unexpected conditions, or quotes terms that make the refinance unworkable, the borrower is in a difficult position if no alternative has been considered.
Maintaining awareness of alternative commercial mortgage routes — either through broker relationships or direct lender conversations — throughout the bridging period does not commit the borrower to using them but ensures they are available if needed. A borrower who knows of two or three credible commercial mortgage routes, even if the first choice is clearly preferred, is in a materially stronger position than one who has invested entirely in a single outcome. Our guide to broker versus direct lender covers how a broker with relevant market knowledge can support access to a wider range of options.
Worked example: a bridge-to-mortgage transition
A manufacturing business identifies an industrial unit that suits its operational needs. The seller is motivated and wants completion within six weeks — faster than a commercial mortgage can be arranged. The unit requires electrical certification and minor structural remediation before a mainstream commercial lender will consider it acceptable security. The business’s trading history is strong and the owner has already had an indicative conversation with a commercial mortgage broker confirming that the business profile is likely to be acceptable to commercial lenders once the property meets their condition standards. The bridging application is structured for a nine-month term: three months for works and certification, with the commercial mortgage application submitted at or shortly after the works completion point, allowing four to five months for underwriting, valuation, and legal completion with a two-month buffer against delays.
The works complete on schedule after eleven weeks and the electrical certification follows two weeks later. The commercial mortgage application, which has been in preparation since the point of purchase completion with accounts and bank statements already assembled, is submitted at week thirteen. Valuation is instructed and completed within three weeks. Legal work takes six weeks, with one set of enquiries requiring a planning confirmation letter that takes two weeks to obtain. The commercial mortgage completes at week twenty-two, within the bridging term and within the planned buffer. The key factors that make this example work are the early feasibility discussion that confirmed the commercial mortgage route before the bridge was agreed, the parallel preparation of documentation during the works period rather than after it, and the buffer time in the bridging term that accommodated the planning confirmation delay without creating a timing crisis. The numbers in this example are illustrative only — actual timelines, costs, and lender requirements vary considerably.
FAQs
How early should the commercial mortgage process start when a bridge is being used?
The general principle is that commercial mortgage preparation should begin at or near the point of purchase completion rather than at any later stage. The commercial mortgage application cannot typically be formally submitted until the property meets the lender’s eligibility conditions — which may require works to be completed, certifications to be obtained, or planning matters to be resolved — but the preparation work that precedes submission can begin immediately. This includes assembling the documentation pack, engaging a commercial mortgage broker, confirming the intended lender’s specific criteria, and establishing what evidence of property readiness will be required at the point of application.
In practical terms, treating the commercial mortgage as something to address once the property is ready rather than alongside the property works is one of the most consistent sources of timing gaps. A business that completes works in month four of a nine-month bridge but only begins commercial mortgage preparation at that point may find that underwriting, valuation, and legal completion cannot be achieved within the remaining five months, particularly if complications arise. Beginning preparation during the works period means the application is ready to progress as soon as the property qualifies, rather than beginning from scratch at that point.
What if the commercial mortgage lender requires the property to be fully ready before progressing?
This is a common position and does not prevent the strategy from working, provided the sequencing is correctly planned. Where a commercial lender will only advance to completion once specific property conditions are met — particular works completed, certifications in place, planning confirmations received — the transition plan needs to identify those conditions precisely and build the works and compliance programme around meeting them within the bridging term. The conditions the commercial lender requires should be established through early feasibility discussions before the bridge is agreed, so that the works programme is designed around the lender’s specific requirements rather than around a general standard.
The risk in this scenario is a works scope that improves the property generally without specifically meeting the commercial lender’s conditions. Works that make the premises usable but do not address the structural or condition flag the commercial lender’s valuer identified will not satisfy the lender’s requirement, and the refinance will remain on hold. Confirming the specific conditions with the intended commercial lender or broker at the outset, and designing the works programme around those conditions, removes the risk of arriving at the refinance stage with works completed but conditions not met.
Can an extended bridging term solve a timing gap?
An extension can resolve a timing gap in some cases, but it is not reliable as a planned solution. Bridging lenders are not obligated to offer extensions, and where they do, extensions typically come with additional fees, potentially revised pricing, and may require an updated valuation of the security. The availability and cost of an extension therefore depends on the lender’s position and the current state of the security at the time the extension is requested, which may be different from the position at the start of the term. An extension that looks straightforward at the outset may be more expensive or less readily available when actually needed.
The more significant risk of relying on extension is that it places the decision-making under time pressure rather than on merit. A business approaching the end of its bridging term without the commercial mortgage in place faces a constrained set of options, and the pressure of that constraint can lead to accepting extension terms or commercial mortgage terms that would not be accepted in a less time-sensitive situation. Planning the transition with a realistic buffer and a contingency route from the outset keeps the decision-making rational rather than reactive. An extension should be a backstop that is available and understood, not the primary plan for managing the end of the term.
What evidence typically supports a refinance exit onto a commercial mortgage?
A commercial mortgage refinance exit needs to address two distinct dimensions: business affordability and property readiness. On the business side, lenders typically require two to three years of full accounts, recent bank statements, management accounts where the last full accounts are more than a few months old, and an understanding of how the proposed mortgage repayments sit alongside existing commitments. Where the business has characteristics that some lenders treat cautiously — a relatively short trading history, a sector with known risk factors, or a complex income structure — understanding the specific lender’s criteria on these dimensions before the bridge is agreed reduces the risk of discovering at the refinance stage that the affordability assumption was not well founded.
On the property side, the commercial lender will require a valuation by a panel valuer, clear legal title, acceptable condition and use class, and resolution of any matters flagged during the bridging period. Where the exit depends on changes during the bridge — works completion, planning confirmation, certification — the evidence of those changes needs to be assembled in a form the commercial lender will accept. A valuation that was carried out at the bridging stage may not be sufficient for the commercial lender’s purposes; the commercial lender will typically instruct their own valuer. Understanding this distinction early, and not assuming that the bridging valuation covers the commercial mortgage requirement, is one of the practical steps that keeps the refinance on track.
Is bridging still appropriate if the commercial mortgage feels close to being ready?
The answer depends on what “close to being ready” means in specific terms. Where a commercial mortgage is at legal stage with a known completion date that is a few weeks beyond the purchase deadline, bridging can be a proportionate and cost-effective way to bridge that specific gap. Where “close” means a lender has expressed interest but underwriting has not been formally progressed, conditions have not been confirmed, and a completion date is not yet identifiable, the gap between apparent proximity and actual readiness can be considerably larger than it appears.
The practical test is whether the remaining steps to commercial mortgage completion are known, their timelines are realistic, and they are all within the control of parties who have committed to progressing them. Legal completion is more predictable than underwriting; underwriting with a formal offer is more predictable than a lender’s indicative interest. The more the “almost ready” position depends on assumptions about how quickly the remaining steps will move rather than on confirmed timelines, the more important it is to ensure the bridging term is long enough to accommodate a less optimistic outcome. A bridge structured around an assumption that the commercial mortgage will complete within six weeks when the realistic range is six to sixteen weeks is a bridge that is likely to encounter a timing gap.
Squaring Up
Bridging while waiting for a commercial mortgage is an effective strategy when the transition is planned as carefully as the purchase. The bridge solves the timing problem; the transition plan solves the handover problem. When both are managed with the same attention, the strategy works cleanly. When the transition plan is vague, optimistic, or sequential rather than parallel, the timing gap that results is almost always more expensive and more stressful than it needed to be.

To model illustrative costs for a specific facility across different term lengths and fee structures, the bridging loan calculator allows all key inputs to be adjusted in one place.
This information is general in nature and is not personalised financial, legal, or tax advice. Bridging loans are secured on property, so the property may be at risk if repayments are not maintained. Before proceeding, review the full costs including interest structure, fees, and any exit charges, understand how much will actually be received as a net advance, and make sure the exit strategy is realistic and time-bound. Consider whether other funding routes could be more suitable and take independent professional advice if unsure.
