You’ve found it. The house with the dodgy roof, no working kitchen or a “structural issue” flagged in bold on the survey. It’s a bargain, it’s got potential and every high street bank has said no,
Welcome to the world of the unmortgageable property and the reason bridging finance exists in the first place.
Why Banks Say No (And Why That’s Not the End of the Story)
The standard mortgage lender wants a property that is safe, liveable and easy to resell if things go wrong. If there’s no kitchen, no bathroom, missing roof tiles, damp or an unusual type of construction (think concrete panel or timber frame) then within seconds a property can be labelled “unmortgageable”.
But the thing is, an unmortgagable property does not mean an unbuyable property. It just means that the old-fashioned 25-year mortgage isn’t the right tool for the job right now. That’s where bridging finance comes in.
What Is Bridging Finance? (Quick Answer)
Bridging finance is a short-term, asset-backed loan usually lasting a few weeks to 24 months used to “bridge the gap” until you can either sell the property or refinance onto a standard mortgage. Unlike a normal mortgage, lenders focus on the property’s value and your repayment plan (your exit strategy), not the property’s current condition.
In plain terms: bridging loans lend against what the property will be worth once it’s fixed up, not just what it’s worth today.
How Bridging Finance Actually Works for an Unmortgageable Property
- You find the property often at auction, where unmortgageable homes are common because sellers need a fast, guaranteed sale.
- A bridging lender values it as-is and sometimes also assesses its Gross Development Value (GDV), i.e. what it’ll be worth once renovated.
- You borrow against that value typically up to 70–75% loan to value (LTV), sometimes higher against GDV if the purchase price is low.
- You complete the purchase fast bridging loans can complete in days, not months, which matters hugely at auction where you often have just 28 days.
- You renovate the property bringing it up to a standard where a normal mortgage lender will accept it.
- You exit the bridge either by selling the property or refinancing onto a standard residential or buy-to-let mortgage.
That last step your exit strategy is the single most important part of the whole deal. Lenders will ask about it before they ask about almost anything else.
A Quick Real-World Example
Say you buy a run down terraced house at auction for £150,000. It needs a new kitchen, bathroom and roof nothing a mortgage lender will touch. You get a bridging loan at 70% LTV, complete it in 10 days, spend three months on renovations, and then refinance onto a standard buy-to-let mortgage once the property is habitable and valued higher. A standard mortgage wouldn’t have been able to bridge the gap, but the bridge did just that.
Regulated vs Unregulated Bridging Loans
This trips a lot of first-timers up, so here’s the short version:
- Regulated bridging loan the property is (or will be) your own home, or a family member’s. The Financial Conduct Authority (FCA) oversees these, adding extra consumer protections.
- Unregulated bridging loan the property is for investment, buy-to-let, or commercial use. These are treated as business transactions and are often faster to arrange.
Neither is “better” it simply depends on what you’re buying and why.
Who Actually Uses Bridging Finance?
- Property investors picking up run-down auction lots at a discount
- Developers funding a refurbishment or conversion project
- Homebuyers who’ve found their dream home but it needs work before a mortgage lender will touch it
- Landlords setting up a “bridge to let” buying, renovating, then refinancing onto a buy-to-let mortgage
- Business owners securing commercial property finance for premises that need fixing up
Before You Apply: A Short Checklist
- Do you have a clear, realistic exit strategy (sale or refinance)?
- Have you budgeted for renovation costs and the bridging loan costs?
- Do you know whether you need a regulated or unregulated loan?
- Have you spoken to a bridging finance broker who can compare lenders for you, rather than approaching just one?
A good broker matters here more than almost any other type of property finance because every unmortgageable property is a slightly different problem, and not every lender says yes to the same things.
Frequently Asked Questions
What is bridging finance? A short-term loan secured against property, used to cover a gap such as buying an unmortgageable property until you sell or refinance.
How long does a bridging loan take? Most bridging loans complete in 7–14 days, and some fast-track deals complete in as little as 3–5 days.
Who can apply for bridging finance? Homebuyers, landlords, developers, and investors can all apply. Approval is based mainly on the property’s value and your exit plan, not your income alone.
Can I get bridging finance with bad credit? Yes. Because bridging loans are asset-backed, lenders focus more on the property’s value and your exit strategy than on your credit score.
What is the maximum LTV for a bridging loan? Typically 70–75% of the property’s current value, though this can be higher when calculated against the Gross Development Value after renovation.
How much does bridging finance cost? Costs vary by lender and deal but generally include a monthly interest rate, an arrangement fee, and legal/valuation fees. Many lenders let you “roll up” interest so nothing is due monthly.
Is bridging finance regulated? Only when the property is or will be your own home or a family member’s. Investment and commercial bridging loans are usually unregulated.
When should I use a bridging loan? When you need to move fast on a property purchase especially at auction or for an unmortgageable property and have a clear plan to repay the loan through a sale or refinance.
