In a busy property market, like the UK’s, speed and the ability to make moves determine who secures the best deal. A traditional buy-to-let mortgage can take weeks to months to arrange, sometimes leading to you being rejected just because the property needs refurbishment.
This is where a domestic bridging loan comes in to save the day. An interest-only, short-term finance option allows investors to act fast, and refinance later, once it’s mortgage-ready.
At Goldhill Finance Limited, we help investors use bridging finance strategically in order to unlock high-return buy-to-let opportunities.
How bridging loans power buy-to-let investment
Bridging finance is ideal for property investors looking to:
1. Buy at auction
Auctions often require completion within 28 days, far too small a timescale for a traditional mortgage to be agreed and granted. Bridging loans allow you to secure the property instantly, then refinance onto a more longer term product at a later date.
2. Refurbish unmortgageable properties
Many buy-to-let lenders won’t lend on properties without kitchens or bathrooms that need heavy work.
3. Expand portfolios quickly
Seasoned landlords are able to use bridging finance to purchase multiple units or refinance any existing assets you may have. This allows you, the landlord, to release equity for any purchases in the future you have in mind.
4. Bridge to let
Buy fast, improve your home, and increase its value. You can then exit into a cheaper buy-to-let mortgage once your property has a tenant and is bringing in money from the rent.
What is the most popular loan amount for a property refurbishment in the UK?
There is no single figure, and any lender that gives you one is simplifying. The market data does give a useful picture, though.
Research puts a common funding amount at around £500,000 to £600,000, with many loans falling in the £200,000 to £1m range. A 2026 lender survey points the same way, with 48% of lenders saying the average loan size was above £600,000. Those numbers cover all bridging, including development exit and larger portfolio deals, so they skew higher than a typical single buy-to-let refurbishment.
For the average landlord, the amount that matters is the one the property supports. Lenders size a refurbishment loan from three things:
- The purchase price or current value. Most first charge bridging loans are written at 55% to 75% loan to value, with average leverage around 60%.
- The refurbishment budget. Many lenders release works funding in stages, once each phase is complete. Average UK refurbishment costs are approaching £86,000 including contingency, so build a buffer into your figures from the start.
- Your exit. The loan has to be repaid by a sale or a refinance, so the lender will test whether the finished property supports a buy-to-let mortgage large enough to clear the debt.
In practice, most refurbishment loans for landlords sit well below the market averages above. A £150,000 to £400,000 loan secured on a single rental property is a far more common brief than a seven-figure facility.
The amount to borrow is the smallest one that completes the purchase and the works with a sensible cushion. Borrowing the maximum feels attractive, but interest is charged monthly. Rates average around 0.88% a month across the market, so every extra £10,000 borrowed costs you roughly £88 a month in interest.
Before you settle on a figure, work through three questions:
- What will the property be worth once the work is finished, and will a buy-to-let lender value it that way?
- Can the rental income support the mortgage you will need to refinance onto?
- If the works run three months over, can you still cover the interest?
If the answer to any of these is unclear, our team can help you size the loan around your project before you commit to a purchase.
The process
- Secure a deal: Find a property that is suitable for your needs, (Auction, off-market, or distressed).
- Apply: Apply for a bridging loan by providing details of purchase, the security you intend to use, and your exit strategy (refinance or sale).
- Add value: Refurbish or convert the property to meet rental and mortgage standards.
- Exit: This is usually done in two ways: Refinancing onto a standard buy-to-let mortgage, or by selling the property to repay the bridging loan.
Advantages for buy-to-let investors

- Opportunity: You will be able to secure auction purchases and any other off-market deals
