TL;DR- Bridge to let is a product combining a short-term bridging loan (for purchase and renovation) with an agreed exit onto a buy-to-let mortgage from the same or related lender.
- The exit BTL mortgage terms are agreed at the outset, providing certainty on the refinancing rate and criteria before the project begins.
- Bridging loan interest is typically charged at a monthly rate (commonly 0.5-1.5% per month) and rolled up until the exit mortgage is taken.
- Bridge to let is used by landlords who buy below-market-value properties requiring renovation, refurbish them to a lettable standard, then refinance onto a long-term BTL.
How Bridge to Let Works
A bridge to let product is a combined finance package offered by some specialist lenders. The borrower takes a short-term bridging loan to purchase and renovate a property, with an agreement from the same lender to provide a buy-to-let mortgage on completion of the works, subject to the property meeting the lender's BTL criteria at that point. The certainty of an agreed exit is the key advantage over arranging bridging and BTL refinancing separately.
The bridging phase typically lasts 6-18 months, during which the borrower purchases the property, carries out the renovation and achieves a rental valuation sufficient to meet the BTL lender's rental coverage test. Once these conditions are met, the bridging loan is redeemed and replaced by the BTL mortgage.
Bridging Loan Costs
Bridging loans charge interest at a monthly rate, typically between 0.5% and 1.5% per month depending on the LTV, the lender and the property type. Interest is usually rolled up (added to the outstanding balance) rather than paid monthly during the bridging period, preserving the borrower's cash flow for the renovation. The rolled-up interest is repaid when the bridging loan is redeemed at the BTL exit.
In addition to the monthly interest rate, bridging loans typically carry an arrangement fee (commonly 1-2% of the loan), a valuation fee and legal costs. The total cost of the bridging phase should be modelled before committing to the project to ensure the post-renovation BTL yield is sufficient to justify the overall investment.
Exit BTL Criteria
The exit BTL mortgage is assessed on the property's rental value and condition after renovation. Lenders require: the property to be in a lettable condition; a rental valuation from an approved surveyor; the rental income to meet the lender's coverage ratio at a stressed rate (typically 125-145%); and the borrower to meet standard BTL eligibility criteria. If the renovation takes longer than planned or the rental valuation is lower than expected, the exit BTL terms may need to be renegotiated.
When Bridge to Let Makes Sense
Bridge to let is used most commonly by experienced property investors who: buy below-market-value properties at auction or through distressed sales; renovate to a lettable standard; and then refinance onto a long-term BTL to release equity and fund the next acquisition. The strategy depends on purchasing sufficiently below market value and executing the renovation within budget to generate an acceptable yield on the final BTL and to release capital for reinvestment.
Frequently Asked Questions
What is the difference between a bridge to let and a standard bridging loan?
A standard bridging loan is a short-term loan with a defined exit, which the borrower arranges separately from their refinancing. A bridge to let product combines the bridging loan and the BTL exit mortgage in a single agreed package from the same lender or group, providing certainty on the exit terms from the outset. The certainty of an agreed exit rate and criteria is the key advantage of bridge to let over arranging the two elements separately.
Can I use a bridge to let product as a first-time landlord?
Some bridge to let lenders require prior landlord experience. Others accept first-time landlords where the borrower has relevant property or professional experience. The renovation management aspect of the strategy is complex - lenders typically assess the borrower's ability to execute the renovation plan as part of the overall risk assessment. First-time landlords should seek specialist advice before committing to a bridge to let strategy.
What happens if the renovation takes longer than the bridging period?
If the renovation overruns and the bridging period expires before the property is ready for the BTL exit, the borrower must apply for an extension of the bridging loan. Most lenders allow short extensions subject to interest continuing to accrue at the monthly rate. Extended periods significantly increase the bridging interest cost and reduce the profitability of the project. Budget and programme contingencies are essential to manage this risk.
Is stamp duty payable on a bridge to let purchase?
Yes. Stamp duty land tax is payable on the purchase price at acquisition. If the borrower already owns a property, the additional dwelling SDLT surcharge also applies. BTL investors are among the most affected by the SDLT surcharge, and this cost should be factored into the investment appraisal for any bridge to let project.
