What Are the Advantages of Bridging Finance?
Speed is the core advantage. A conventional mortgage takes four to eight weeks. A bridging lender can issue a formal offer within one to three days of valuation and complete within two to three weeks on a clean case.
If you’re buying at auction, where you have 28 days to complete, nothing else moves fast enough. If your buyer has pulled out and you don’t want to lose your onward purchase, a bridge is often the only tool that works.
Underwriting is more flexible than a mortgage. Bridging lenders focus on the security value and your exit plan, not income multiples or credit scores. If you have CCJs, limited trading history, or non-standard income, you may qualify for a bridge when mainstream lending is closed to you.
Rolled-up interest removes the monthly cash burden. You don’t make payments during the term, interest accrues and is repaid with the capital when the bridge redeems. If your sale or refinance completes early, you pay only for the months you actually used.
What Are the Disadvantages of Bridging Finance?
Cost is the main disadvantage. A rate of 0.85%/month sounds small, but compounded over 12 months, it costs you closer to 11.2% on the outstanding balance before any fees.
We compared all-in costs across 13 lenders and found that a £200,000 bridge for 12 months, arrangement fee, exit fee, legal costs on both sides included, typically runs to 14% to 16% of the loan. That’s the number to use when you’re deciding whether a bridge makes sense.
Your property is at risk if your exit fails. If the sale falls through or your refinance lender rejects you at the last stage, default interest starts at 2% to 4% per month above your contracted rate, from day one of the overrun.
Extension fees add a further 0.5% to 1.5% of the outstanding balance. Prolonged default leads to enforcement: receiver appointment, possession proceedings, or a forced sale at a discount to recover what you owe.
Unregulated bridges, the majority of commercial and investment transactions, carry no FCA protections. No right to a payment holiday, no access to the Financial Ombudsman, and no FSCS cover.
This is standard in commercial finance, but it is a meaningful difference from a regulated residential mortgage.
What You’ll Actually Repay: Calculating the True Cost Before You Commit
Before you draw down a bridge, calculate the all-in cost, not just the headline rate. The formula: (monthly rate × term in months) + arrangement fee + exit fee + legal fees on both sides + valuation cost.
We modelled this on a £250,000 bridge at 0.85%/month for six months: £12,750 interest, plus 1.5% arrangement (£3,750), 1% exit fee (£2,500), £2,500 in legal costs, £750 valuation. Total: £22,250, around 8.9% of the loan.
That cost is justified if you’re buying an auction property at £40,000 below market value. It’s not justified if you need short-term working capital that a business overdraft could cover at 2% a year.
One practical test: if a cautious friend wouldn’t lend on your exit plan, a commercial lender probably won’t either. Your bridge should have a documented exit with a realistic safety margin, not a hope.
When Bridging Finance Is the Right Answer
Use a bridge when conventional finance can’t move fast enough or won’t lend on the property as it stands.
Auction purchases are the clearest example. You have 28 days to complete. No mainstream mortgage lender moves that quickly. If you’re bidding at auction without a bridge in place, you’re bidding with finance you can’t actually deliver.
Unmortgageable properties, those in dilapidated condition, lacking a kitchen or bathroom, or with structural defects, cannot be funded with a standard mortgage until works are done.
A bridge buys the property and funds the refurbishment. Your term mortgage replaces it once the property meets lender criteria.
If your buyer has pulled out and you don’t want to lose your onward purchase, a chain-break bridge fills the gap. You complete, find a new buyer for the original property, and repay when the sale goes through.
Time-sensitive commercial deals, a vendor with a hard deadline, an expiring planning consent, or a competitive tender, also suit bridging. We’ve found the speed premium is frequently justified by the deal economics in these cases.
When Bridging Finance Is the Wrong Answer
Don’t bridge when your exit is speculative. A sale at asking price isn’t a committed exit. An AIP letter isn’t a mortgage offer. A GDV figure isn’t cash in hand. Lenders assess exits sceptically, and so should you.
It’s the wrong answer when cheaper finance could do the same job. A business overdraft, remortgage, or further advance on an existing mortgage all cost significantly less. If any of them can deliver the funds in time, they are the better choice.
It’s also the wrong answer when your equity cushion is thin. If a forced sale at a discount would leave you short, the risk is too high. We found that borrowers who got into serious difficulty on bridges typically had less than 30% equity in the security at the outset.
Ask yourself: if a cautious friend reviewed this exit plan, would they be comfortable lending on it? If the answer is no, don’t draw the bridge down.
Bridging Finance FAQs
Is bridging finance a good idea?
It depends entirely on the transaction. We assess bridging as expensive, typically 8% to 16% all-in annually, but it solves problems that cheaper finance cannot. For auction purchases, chain breaks, or unmortgageable properties with a credible exit, it’s often the only tool that works. For most other needs, we recommend considering cheaper alternatives first.
What happens if I cannot repay a bridging loan on time?
Default interest starts on the first day of overrun, typically 2% to 4% per month above the contracted rate. Extension fees are usually charged at 0.5% to 1.5% of the outstanding balance. If an extension cannot be agreed, the lender can enforce against the security, appointing a receiver, seeking possession, or forcing a sale. Contact your lender before the term ends, not after. Most lenders will negotiate an extension in advance; few will extend once you are already in default.
Can I get a bridging loan with bad credit?
Yes, in many cases. Specialist lenders such as MT Finance and Streambank assess applications on the security value and the exit plan rather than credit scores. CCJs, arrears, and adverse credit history are considered if the property provides adequate cover. Rates will be higher and LTVs lower, but regulated and unregulated bridges are available to borrowers who would not qualify for mainstream mortgage finance.
How long does a bridging loan take to arrange?
A clean, straightforward case typically takes two to three weeks from enquiry to drawdown. We found that the legal work on both sides is often the final bottleneck, not the lender’s credit decision. AVM-based valuations speed up simpler cases; physical valuations add several days. Complex transactions with multiple securities or unusual property types take longer.
What is the minimum deposit for a bridging loan?
There is no deposit in the traditional sense. Bridging lenders lend up to a maximum loan-to-value, typically 75% for first-charge facilities on residential or commercial property. This means the borrower needs to contribute at least 25% of the property value, plus cover all fees. Second-charge bridges are capped at lower combined LTVs (65% to 75% of total property value).
