Bridging loans for property investors
- Bridging finance is priced monthly, not annually - a 1% per month rate equals approximately 12% per year before fees.
- Arrangement fees, exit fees, and legal costs add substantially to the headline rate.
- The exit strategy must be confirmed before you start the bridge, not worked out during it.
- Common uses: auction purchases, uninhabitable properties, chain breaks, BRRR refurb phase.
- Never start a bridge without a clear, achievable exit. Being stuck in a bridge is expensive and stressful.
What bridging finance is and when to use it
A bridging loan is a short-term secured loan used to "bridge" a gap between needing money now and a longer-term finance solution becoming available. The loan is secured on property and typically lasts from 1 month to 24 months.
In property investment, the most common uses are:
Auction purchases: Auction completions are typically required within 28 days. Arranging a standard BTL mortgage in 28 days is difficult or impossible. A bridging loan, which can complete in 5-10 working days, allows you to complete within the auction window and then replace it with a long-term mortgage.
Uninhabitable properties: Most standard BTL mortgage lenders require a property to be in habitable condition. A property needing significant renovation - no kitchen, no bathroom, damp throughout - will not be accepted for a standard BTL mortgage. A bridging loan funds the purchase and renovation, after which the property is refinanced onto a BTL mortgage.
Chain breaks: If your purchase is at risk of falling through because a property in your chain collapses, a bridge can fund the purchase of your property before your sale completes.
BRRR strategy: Bridging is the standard finance tool during the refurbishment phase of a BRRR deal (see the BRRR strategy guide for detail).
The common thread: bridging finance is appropriate when speed is required and when the property in its current state cannot access longer-term finance. It should not be used because it is the only finance someone could access - the exit must be clear.
How bridging loans are priced
Bridging loans are not priced annually like mortgages. They are priced monthly. This is important to understand when comparing costs.
A typical bridging loan rate in 2026: 0.75-1.2% per month.
To translate to annual equivalent: 0.85%/month x 12 = 10.2% per year. Add arrangement fees (typically 1-2% of the loan amount) and you are looking at an effective annual cost of 11-14% on the principal.
Interest can be charged in two ways: - Retained interest: The lender calculates the total interest for the agreed loan term upfront and deducts it from the advance. If you borrow £100,000 for 9 months at 0.9%/month, the lender retains £8,100 of interest and advances £91,900. This means you are effectively borrowing slightly less than the headline loan amount. - Rolled up interest: Interest accrues on the outstanding balance and is paid at redemption. If the project completes in 6 months rather than 9, you pay less interest.
Most investors prefer rolled-up interest because it means you pay only for the time you use.
Other fees to include in your cost calculation: - Arrangement fee: 1-2% of loan amount (often deducted from advance) - Exit fee: 1% of loan amount on redemption (not all lenders charge this) - Valuation fee: £300-£600 - Legal fees: £800-£1,500 (both lender's and your own legal costs)
First and second charge bridging
A bridging loan can be secured as a first charge (the primary debt against a property) or a second charge (an additional loan against a property that already has a first charge mortgage).
First charge bridging is used when there is no existing mortgage on the property. This is the most common structure for property purchases. The bridging lender has first claim on the property if the loan defaults.
Second charge bridging is used when you want to raise money against a property you already own with a mortgage. The bridging lender takes a second charge, behind the existing mortgage lender. Second charge lending is more expensive (the lender has higher risk) and requires the first charge lender's consent in most cases.
Investors sometimes use second charge bridging on an existing property to release equity to fund the deposit for another purchase. This can work but stacks risk: if both properties have issues simultaneously, you could be under pressure on two loans at once.
The LTV (loan-to-value) available on bridging loans: - First charge: typically up to 70-75% of the current market value, or 70% of the purchase price, whichever is lower - Second charge: typically up to 65-70% of the combined property value minus the first charge balance - Development bridges with additional funds for refurb: typically 65-70% of the end value (GDV)
Exit strategies
Every bridging loan must have a defined exit strategy - the mechanism by which the bridge will be repaid. Lenders require this at application. The most common exits are:
Refinance onto a BTL mortgage: The most common exit for investment bridges. The property is completed, refurbished if necessary, tenanted, and then refinanced onto a standard BTL mortgage which repays the bridge. The key risk: the refinance valuation must come in at a high enough level for the BTL mortgage to fully repay the bridge.
Sale: The property is sold and the sale proceeds repay the bridge. Used for pure development projects or where the investor does not want to retain the property.
Longer-term commercial mortgage: For commercial or semi-commercial properties, the exit may be a commercial mortgage rather than a residential BTL product.
Before you start a bridge, be able to answer clearly: - What is the exit? - What LTV will I need to achieve at refinance? - What valuation does the property need to come in at? - What are the ICR (interest coverage ratio) requirements at refinance? - What rent level is needed to pass ICR at the target LTV?
If you cannot answer all of these convincingly, your exit is not confirmed. Do not start the bridge.
Regulated vs unregulated bridging
Bridging loans can be regulated or unregulated, and this distinction matters.
Regulated bridging: Applies when the borrower (or their immediate family member) lives or intends to live in the property. Regulated bridges are subject to FCA oversight, giving borrowers additional protections including the right to complain to the Financial Ombudsman Service. Rates are typically slightly lower.
Unregulated bridging: Applies to investment properties where the borrower does not live and does not intend to live. The vast majority of investment property bridging falls into this category. There is no FCA protection, so the terms are entirely determined by the contract. Read it carefully.
For pure investment property bridges, the key consumer protection is choosing a reputable, well-established bridging lender. Stick to lenders who are members of the Association of Short Term Lenders (ASTL) and have a track record. Unscrupulous bridging lenders are rare but do exist, and the consequences of dealing with one when you are mid-refurbishment with an uncompleted exit can be severe.
The risk of getting stuck in a bridge
"Stuck in a bridge" is when you cannot repay the bridging loan at the end of the agreed term and the lender will not extend. This is a serious situation.
How it happens: - The refurb overruns and the property is not ready to refinance within the bridge term - The refinance valuation comes in below what is needed to repay the bridge - Interest rates rise sharply and the BTL lender's ICR test can no longer be passed at the required LTV - A structural problem is discovered during works that prevents completion
Consequences: - Monthly interest continues to accrue (and typically at a higher "default" rate) - Extension fees apply (0.5-1% per additional month) - The lender may appoint a receiver or take possession proceedings if the default continues
Prevention: - Build a contingency of 3-6 months beyond your expected project timeline - Model a 15-20% down-valuation scenario and confirm you can still exit - Have access to reserve capital that can top up the repayment if the valuation is slightly short - Choose a bridging lender who is flexible and transparent about extension terms before you start
Bridging finance is a powerful tool for property investors. But it is not forgiving. The costs of misjudging a project on a bridge are considerably higher than the costs of misjudging on a standard BTL mortgage.
