Bridge to Commercial Mortgage Timeline
How a bridge-to-commercial-mortgage transition works
The two scenarios below show what happens when preparation runs in parallel versus in sequence
How to use this tool
Use the tabs to switch between the two scenarios. Each shows when the bridging loan is running, when property works are underway, and when commercial mortgage preparation needs to be in progress to allow a clean exit at the end of the term.
The key question this tool is designed to answer is not how long a commercial mortgage takes, but when to start the process. In most refurbishment cases using a standard 12-month bridge, the answer is considerably earlier than feels natural — typically while works are still ongoing rather than after they finish.
What the two scenarios show
Parallel preparation: starting early
In the parallel scenario, commercial mortgage preparation begins around month 3 of the bridge, while property works are still underway. This is not premature. Lenders and valuers can assess a property and issue an offer in principle subject to satisfactory completion of works. Starting at this point means valuation, underwriting, and legal work are substantially complete before the works finish. The mortgage is typically ready by month 9 or 10, leaving a buffer before the bridge expires at month 12. In most cases, no extension is needed and no additional interest cost is incurred.
The parallel approach requires some discipline: engaging a broker or lender early, providing detailed works specifications before completion, and managing two processes simultaneously. The administrative effort is real. But it is considerably smaller than the cost of a bridge extension — typically 0.75% to 1% per month on the gross loan — and it removes the risk of a forced sale or default at the end of the term.
Sequential preparation: the common mistake
In the sequential scenario, commercial mortgage preparation does not begin until works are complete, usually around month 5 or 6. This feels logical: the property is not in its finished condition, so why apply? The problem is that the commercial mortgage process — desktop valuation, full valuation, underwriting, legal work — typically takes six to eight months when completed thoroughly. Starting at month 6 means the mortgage is rarely ready before month 13 or 14.
By that point, the bridge has already expired. The borrower faces either requesting an extension at additional monthly interest cost, arranging a second bridging facility, or in the worst case a forced sale. None of these are planned outcomes and all of them are avoidable with earlier preparation. The sequential pattern is not usually the result of poor intent. It is the result of treating the mortgage as the next problem to solve once the works are done, rather than a parallel process that needs to start alongside them.
Squaring Up
The gap between a bridging loan expiring and a commercial mortgage completing is one of the most common sources of cost overrun in property refurbishment cases — and one of the most preventable. Starting commercial mortgage preparation while works are still ongoing adds complexity to the process but removes the timing risk almost entirely.
