How buy-before-you-sell bridging works
A bridging loan secured against your current home (and often the new one too) gives you the funds to complete on your new property now. You repay the bridge when your existing home sells. It effectively makes you a cash buyer — stronger in negotiations and free from chain delays. The best buy-before-you-sell bridge gives a realistic window to sell and a clearly affordable exit.
1. Bridging secured on your current home
The simplest structure: borrow against the equity in your existing property to fund the new purchase. Best when you have substantial equity and a sellable home. The loan is cleared from the sale proceeds.
2. Dual-security bridging (current + new property)
Securing against both properties lowers the loan-to-value and can unlock a better rate, because the lender has more security. Best for movers who want the keenest pricing and have good equity across both.
3. Open bridging with a sale window
If your home isn't yet under offer, an open bridge gives you up to around 12 months to sell. Price your home to sell within that window rather than holding out for top dollar. Best when you need to move quickly but the sale is still to come.
4. Rolled-up interest bridging
To avoid paying your existing mortgage, the new purchase costs and bridging interest every month, most movers roll up the bridging interest and settle it from the sale. Best for protecting monthly cash flow while you own two homes.
The costs and the exit
- Interest — charged monthly (paid or rolled up), higher than a mortgage but only for a short period
- Fees — arrangement, valuation and legal costs
- The exit is the sale — price realistically so it completes within your term
- Two properties — budget for running both until the sale completes
Is buying before selling right for you?
It's ideal when the new home is worth securing now and your current one is genuinely sellable with solid equity. It's the wrong move if your sale is very uncertain or your equity is thin — the cost of holding two properties can mount. A specialist confirms the numbers and exit stack up before you commit.
How to find the best buy-before-you-sell bridge
Single vs dual security, open vs closed, rolled-up interest — the best structure depends on your equity and how far along your sale is. A bridging specialist will match it and find a competitive rate. Find a bridging finance specialist through Nesto — free, no obligation.
Frequently asked questions
Can I really buy a new home before selling mine?
Yes — bridging finance funds the new purchase now and is repaid when your current home sells, effectively making you a cash buyer.
Is it secured on my old or new home?
Either or both. Dual security (both properties) lowers the loan-to-value and can secure a better rate.
How long do I get to sell?
Open bridging typically allows up to around 12 months. Price your home to sell comfortably within the term.
Do I pay two mortgages plus the bridge?
You can roll up the bridging interest to protect monthly cash flow, settling it from the sale proceeds.
What if my home doesn't sell in time?
Always price realistically and keep your lender informed. Extensions may be possible but add cost — a broker builds in a sensible time buffer from the start.
