Bridging Loans for Property Sales, When They Help and When They Are a Trap

What is a Bridging Loan?

A bridging loan is a short-term secured loan used to "bridge" a gap between two financial positions, most commonly the gap between needing to complete a property purchase before the proceeds from another property have been received.

Bridging loans are secured against property and are designed to be repaid within a short period, typically between one month and 18 months. They are arranged more quickly than standard mortgages, sometimes within days, but at significantly higher cost.

Open vs Closed Bridging Loans

The most important distinction in bridging finance is between open and closed loans.

**Closed bridging loan:** Has a fixed repayment date, typically because the source of repayment is already contractually committed. For example, if you have exchanged contracts on the sale of your current property and have a fixed completion date, a bridging lender will consider this a closed bridge. The lender has high confidence that the repayment will arrive on a specific date.

**Open bridging loan:** Has no fixed repayment date. The borrower intends to repay from the sale of a property or another source, but the timing is not contractually guaranteed. Open bridging loans are higher risk for the lender and therefore attract higher interest rates.

How Bridging Loans Work in a Property Chain Context

The most common use case for a bridging loan in a domestic property context is to prevent a chain break.

**Scenario:** You have found a property you want to buy and have had an offer accepted. Your own property is on the market but has not yet sold, or has sold but the buyer's own sale has fallen through, breaking the chain.

Without a bridging loan, you either lose the property you want to buy or you are forced to wait, sometimes months, for the chain to reform.

With a bridging loan, you borrow against the equity in your current property (or both properties) to fund the purchase of the new property. You then sell your current property as planned and use the proceeds to repay the bridging loan.

Interest Rates and the Real Cost

Bridging loan interest is typically quoted monthly rather than annually. This is important because it makes the cost appear lower than it is.

A rate of 0.75% per month converts to approximately 9% per annum, before arrangement fees, exit fees, and legal costs are added. This is substantially higher than standard mortgage rates.

**Example: Total cost of a bridging loan**

• Loan amount: £300,000
• Term: 6 months
• Monthly interest rate: 0.75%
• Monthly interest charge: £2,250
• Interest over 6 months: £13,500
• Arrangement fee (typically 1–2%): £3,000–£6,000
• Exit fee (some lenders, typically 1%): £3,000
• Valuation and legal costs: £1,500–£3,000

**Total cost over 6 months: approximately £21,000–£26,000**

This is the true cost of a bridging loan. It is not a cheap option, and any financial analysis must factor in all these costs, not just the headline monthly rate.

Loan-to-Value (LTV) Limits

Bridging lenders assess how much they will lend based on the value of the security, the property being charged. Typical LTV limits are:

• First charge bridging (no existing mortgage): up to 75% LTV
• Second charge bridging (existing mortgage in place): up to 65% LTV

**First charge** means the bridging loan is the only secured debt against the property. **Second charge** means there is already a mortgage on the property and the bridging loan sits behind it in the repayment queue.

Second charge bridging is more expensive and has lower LTV limits because the bridging lender has less security, in a forced sale, the first charge mortgage lender is paid first.

The Exit Strategy Requirement

Every bridging lender will require you to demonstrate a credible exit strategy before agreeing to a loan. They will not lend against a vague intention to sell.

A strong exit strategy includes:

• A sale already agreed (ideally with contracts exchanged)
• Evidence of the property's marketability if no sale has been agreed
• A realistic timeline for the sale

If you are obtaining a bridging loan before exchanging contracts on your sale, an open bridge, the lender will typically instruct their own valuer on your property and may place conditions on the loan based on the valuation.

When a Bridging Loan Helps

Bridging finance genuinely solves specific problems that standard mortgages cannot address:

**Chain break prevention.** The clearest use case. If losing your purchase would cost you more than the bridging loan, the loan may be the right answer.

**Purchasing at auction.** Auction purchases require completion within 28 days. Standard mortgages cannot be arranged that quickly. Bridging finance can.

**Unmortgageable properties.** Properties without a functioning kitchen, bathroom, or heating system, or properties with structural issues, often cannot get a standard mortgage until the issues are resolved. A bridging loan funds the purchase and refurbishment; a standard mortgage is then arranged on the improved property.

**Breaking a dependency on a slow buyer.** If your sale is delayed by a slow buyer while your purchase is at risk, bridging can allow the purchase to proceed independently.

When a Bridging Loan Is a Trap

Bridging loans become dangerous when:

**The exit strategy is uncertain.** If you borrow to buy before your own property has sold, and your property then fails to sell quickly, you are paying 0.75% per month on a large loan indefinitely. Most bridging lenders will extend the term, but they will also charge extension fees. The costs compound rapidly.

**The property value drops.** If you take a bridging loan at 70% LTV and the value of the security property falls, you may find yourself in a position where the sale proceeds will not repay the loan in full.

**The property being purchased cannot be refinanced onto a standard mortgage.** If the plan is to bridge onto a standard mortgage after purchase but the property turns out to have issues preventing a standard mortgage, the exit strategy fails.

**You underestimate all-in costs.** Borrowers frequently focus on the monthly interest rate and forget arrangement fees, exit fees, and legal costs. The total cost of a bridging loan is often double the headline monthly interest calculation.

Alternatives to Consider First

Before committing to a bridging loan, consider:

• **Renegotiating completion dates** with both your buyer and your vendor
• **Delaying exchange** on your purchase to allow your sale to catch up
• **Requesting a part-exchange arrangement** with a new-build developer
• **Using a specialist chain-break service** offered by some estate agents
