When Bridging Loans Are Used
Scenario
How a bridging loan helps
Buying before selling
Buy new home before your current one sells
Property chain break
Your buyer pulls out — bridge the gap while finding a new buyer
Auction purchase
Must complete in 28 days — too fast for a mortgage
Renovation project
Finance a property that’s unmortgageable in its current state, then remortgage after renovation
Land purchase
Buy land for development before planning permission is confirmed
Business cash flow
Short-term finance against commercial property
Probate property
Buy an inherited property from the estate before it’s fully settled
Conversion projects
Convert commercial to residential, then remortgage
Types of Bridging Loan
Open vs Closed
Type
Detail
Closed bridging loan
Has a fixed repayment date (e.g. “repay within 6 months”). Cheaper because the exit strategy is confirmed (e.g. exchange of contracts on property sale)
Open bridging loan
No fixed repayment date (but a maximum term, usually 12 months). More expensive and riskier
First Charge vs Second Charge
Type
Detail
First charge
The bridging loan is the primary loan against the property (no existing mortgage) — lower interest rates
Second charge
There’s already a mortgage on the property, and the bridge sits behind it — higher rates, the existing mortgage lender must agree

How Interest Is Charged
Method
How it works
Monthly (serviced)
You pay interest each month out of pocket. Cheaper overall but requires cash flow
Rolled up
Interest is added to the loan balance and paid at the end. No monthly payments — but the total is higher
Retained
Interest for the full term is deducted from the loan upfront. You get less cash but have no monthly payments
Example: £200,000 at 0.7%/month for 6 months

Exit Strategies
Your exit strategy is how you’ll repay the bridging loan. Lenders require a clear exit before they’ll lend:

Remortgage
Refinance onto a standard mortgage once the property is mortgage-ready
Refinance with development finance
