If you are looking to take out a £500k bridging loan, you’re probably not planning a typical long-term mortgage. A bridging loan is short-term financing which has been designed to help you move quickly in property deals or solve a cashflow gap, but they’re not cheap and they’re not for everyone.
What is a bridging loan?
A bridging loan is short-term finance secured against property. A lender will typically see this type of loan as a higher risk than a normal mortgage, this is why you’ll pay higher interest.
A bridging loan is usually arranged for a term of 1 – 12 months, sometimes up to 24 with a payment plan in place. A bridge loan will then be repaid either when you sell a property or refinance it with a longer-term mortgage.
What could you use a £500k bridging loan for?
The typical use for a bridging loan in the UK includes the following:
1. Buying before you sell
If you are looking to purchase a new home before your current one has been sold, a bridging loan will let you complete the purchase before the sale of your current one has finshed.
2. Auction property finance
Purchasing at auction usually requires completion within a matter of weeks. A standard mortgage can’t move this fast, but a bridging loan can, at Goldhill Finance we can usually let you know about your approval within 2 hours and fund you within 48 hours.
3. Renovation or refurbishment
Most investors will use bridging finance to buy a property, quickly renovate it and then sell or remortgage.
4. Development exit finance
If you are building or developing and need the time to finish and sell, a bridging loan from Goldhill Finance can help to “bridge the gap” until longer-term funding has been secured.
5. Business cashflow
We understand that businesses sometimes need short-term funds secured against property assets, bridging loans can provide you with this solution.
Calculating your costs
Before you commit to a bridging loan, we advise that you run the numbers through our bridging loan calculator.
This online tool will estimate:
- The monthly interest charges
- The total amount of interest over the term
- The Loan-to-Value (LTV)
- Fees and arrangement costs
All you have to put in is:
- The loan amount you want to apply for (£500,000)
- The term (how many months you want to take out the loan)
- The property value you are using as security
- If you have any current outstanding mortgages
Our calculator will then show you what the interest and total costs might be.

Below itemises the borrowing of £500K on a bridging loan:
| Item | Value |
|---|---|
| Purchase Price (Security Property) | £650,000 |
| Loan Requested | £500,000 |
| Term | 12 months |
| Net LTV | 76.9% |
| Interest Rate | 1.35% per month |
| Monthly Interest | £500,000 × 1.35% = £6,750 |
| Total Interest (12 months) | £6,750 × 12 = £81,000 |
| Lender Arrangement Fee (1%) | £500,000 × 1% = £5,000 |
| Loan Amount | £500,000 |
| Arrangement Fee | £5,000 |
| Total Interest | £81,000 |
| Total to Repay | £500,000 + £5,000 + £81,000 = £586,000 |
500k bridging loan interest rate – What you’re likely to see
The interest on a bridging loan is charged monthly, not annually, this means it’s usually higher than a regular mortgage due to the short-term and riskier nature of the funding.
The current UK market looks roughly like the below:
- Typical bridging loan interest rates run from about 0.5% – 1.5% per month depending on LTV, type of security and exit strategy.
- Stronger cases with lower LTV might see 0.55% per month, some-times it can be slightly less.
- More complex or higher-risk loans can be towards the 1.2%+ range.
That means:
- 0.5% per month ≈ 6% annualised
- 1.5% per month ≈ 18%+ annualised
Fees to expect – Not just interest
Alongside the interest that you’ll pay, you will also see a range of other fees that the UK bridging loan calculator will include or separately itemise:
- Arrangement / facility fees – This is typically 1–2% of the loan.
- Valuation & legal fees
- Broker fees (if you use one)
- Exit fees in some deals
All of these fees can add significantly to the overall cost of your bridging loan if you’re not careful.
Who takes out a £500k bridging loan?

- Auction buyers – Purchases at auction usually need completing quickly.
