What Is a Buy Before You Sell Mortgage?
A buy before you sell mortgage is a financing solution that allows homeowners to purchase their next property before completing the sale of their current one. In the UK, this is usually achieved through bridging finance, a short-term secured loan that “bridges the gap” until the existing property is sold and a standard mortgage or sale proceeds repay the facility.
For buyers in London, where property moves quickly and competition is intense, this type of finance can mean the difference between securing a dream home and losing it to another bidder.
When to Use a Buy Before You Sell Mortgage in London
Typical situations where homeowners turn to this solution include:
-
Chain Breaks – Avoiding transaction collapse when your buyer withdraws or delays.
-
Upsizing or Downsizing – Securing a new property while awaiting sale completion of your existing one.
-
Relocation – Moving quickly for work, education, or lifestyle reasons.
-
New-Build Deadlines – Meeting developer completion dates without waiting on a sale.
Fraser Bond advises clients to use buy before you sell mortgages strategically, particularly when timing is critical.
How Buy Before You Sell Mortgages Work
-
Loan Structure – Usually arranged as a bridging loan secured against your current and/or new property.
-
Term – Short-term, typically 3 to 12 months.
-
Repayment – Cleared once your existing property sells or a long-term mortgage is secured.
-
Costs – Monthly interest (0.4% to 1.2%), plus arrangement fees (1–2%) and legal/valuation costs.
The key is having a clear and achievable exit strategy — most commonly through the sale of your current home.
