Key differences at a glance
A mortgage is a long-term loan (typically 25–35 years) secured against property, with low interest rates and monthly repayments. A bridging loan is short-term (typically 1–18 months) with higher rates but much faster completion.
The fundamental difference is speed and flexibility. A mortgage takes 4–12 weeks to arrange; a bridging loan can complete in days.
When to use a bridging loan
- Auction purchases: You need to complete within 28 days
- Chain breaks: Buying before your current property sells
- Renovation projects: Property is uninhabitable and unmortgageable
- Quick commercial purchases: Time-sensitive business property deals
- Development finance: Purchasing land or property for development
- Probate property: Buying from an estate that needs quick completion
💡 If your exit strategy is to refinance onto a mortgage, get a mortgage Decision in Principle before taking out the bridging loan. This confirms your exit is viable.
When to use a mortgage
- Standard property purchases: Where timing isn't critical
- Long-term ownership: You plan to live in or keep the property
- Lowest cost: Mortgage rates are 3–5x cheaper than bridging rates
- Regular income: You have stable employment and can demonstrate affordability
Cost comparison
On a £200,000 loan over 6 months, a bridging loan at 0.65% monthly with a 2% arrangement fee would cost roughly £11,800 in interest and fees. A mortgage for the same amount at 5% annual interest would cost about £5,000 over the same period.
However, this comparison only works if you can get a mortgage as quickly. If the speed of a bridging loan secures a property that would otherwise be lost, the extra cost may be worthwhile.
⚠️ Never use a bridging loan without a clear, realistic exit strategy. If you can't repay the bridge on time, you risk losing the property.
Using both together
Many property buyers use a bridge to secure a purchase quickly, then refinance onto a mortgage once the urgency has passed. This 'bridge to term' strategy gives you the speed of bridging finance with the long-term affordability of a mortgage.
