The right comparison is not simply the lowest headline rate. Match the facility to the asset being funded, the evidence available, the expected duration, the operational work required and the event that repays it. A cheaper product used for the wrong job can create more delay, covenant pressure or refinancing risk than a correctly structured specialist facility. Funding logic **Time horizon** Bridging is for short deadlines and transitional periods. Repayment logic **Decision basis** Security, valuation, legal route and exit dominate. Main watch-out **Watch-out** A mortgage may be too slow for auction or chain-break deadlines. Check eligibility · About 2–3 minutes, no credit search. Bridge or commercial mortgage: comparison table | Question | Usually stronger when | Watch-out | | --- | --- | --- | | Time horizon | Bridging is for short deadlines and transitional periods. | Commercial mortgages suit long-term property ownership. | | Decision basis | Security, valuation, legal route and exit dominate. | Affordability, income and longer-term servicing dominate. | | Speed | A bridge can be faster if the file is clean. | Commercial mortgages usually take longer to underwrite. | | Watch-out | Never use bridging as long-term debt by accident. | A mortgage may be too slow for auction or chain-break deadlines. | Which suits you ### Bridge or mortgage, by situation. | Your situation | Usually the better fit | Why | | --- | --- | --- | | Auction or chain-break deadline | Bridge | Speed; a mortgage may not complete in time | | Long-term ownership with steady income | Commercial mortgage | Lower cost over years | | Property not yet mortgageable (works, vacancy) | Bridge, then mortgage | Fix the issue, then refinance | | No credible refinance or sale | Neither yet | A bridge needs a defined exit | Worked example ### A bridge, then a mortgage. A business buys a £600,000 unit with a £390,000 bridge to meet a deadline, then refinances onto a commercial mortgage in month 6. Used for six months the bridge does its job; left for years it would be the expensive way to own the building.

Use a bridge for a short-term timing problem, not as a substitute for long-term affordability. #### Speed A bridge may complete faster when evidence and legal work are ready. #### Term Commercial mortgages are designed for longer-term ownership and scheduled repayments. #### Exit A bridge must repay from sale, refinance or another defined route within the term. Examples are educational only.

Check early that the property and your income will meet the mortgage lender’s criteria. **Which is cheaper?** A commercial mortgage, over the long term. A bridge costs more per month but can be cheaper overall when it saves a deal or is used for a few months only. **How long does a bridge last?** Typically up to 12 months, sometimes longer. It is repaid in one payment at the exit. **Do I need accounts for a bridge?** The decision rests mainly on the property and the exit, but lenders still check the borrower and the people behind it.
