How bridging works
Interest modes
- Serviced: pay monthly — needs income
- Rolled up: compounds, repaid at end — no monthly outgo
- Retained: pre-paid from loan, you receive less net
When bridging makes sense
- Chain break — buy before your sale completes
- Auction purchases (28-day completion)
- Refurbish-to-sell projects
- Quick-turnaround commercial deals
Frequently asked questions
What is a bridging loan?
A short-term secured loan used to fill a gap — typically between buying a new property and selling an existing one, or until a longer-term mortgage is in place. Terms are 3–18 months; rates are monthly, not annual.
What does 'serviced' vs 'rolled up' mean?
Serviced: you pay interest monthly. Rolled up: interest compounds and is repaid in one lump at the end. Retained: interest for the term is deducted from the loan upfront — you receive a smaller net amount.
How much is a typical bridging rate?
UK bridging rates are 0.5–1.2% per month (6–15% annualised). First-charge regulated bridging is cheaper; second-charge or unregulated is more expensive. Arrangement fees are typically 2% of the loan.
What's a good exit strategy?
Lenders need a clear exit. Common exits: (1) remortgage onto a standard product, (2) sale of another property, (3) maturing investment. No viable exit = no lending.
Is bridging regulated?
Bridging on a property you intend to live in is FCA-regulated. Bridging on BTL/commercial is unregulated. Both are secured against property.
