If you are selling and buying this autumn, timing matters more than ever. Moneyfacts says the average mortgage deal now stays on sale for just 13 days before it is changed or withdrawn, down from 14 days in September.
What the 13-day figure means
Moneyfacts' UK Mortgage Trends Treasury Report (October 2026) shows how quickly lenders are repricing. For comparison, the average shelf life was 43 days in 2019 and 20 days in 2025. This year it fell as low as 8 days in April, after the US-Iran conflict first hit markets.
Moneyfacts' Adam French called it "the most challenging mortgage market in modern records". Each swing in swap rates feeds through to lender pricing, often at short notice.
Meanwhile the Bank of England base rate is 3.75%, held at the September meeting. The next decision is due on Thursday 5 November 2026.
Why movers feel it most
A remortgage can often be lined up months ahead. A home move is different: you need an accepted offer, a valuation and a full application before a lender will issue a mortgage offer. If the deal you were quoted is withdrawn before your application goes in, you may have to look again at a different price.
Once a mortgage offer is issued, it is usually valid for a set period (commonly several months, depending on the lender). Long chains can run close to that limit, so it pays to know your offer's expiry date and keep your solicitor and estate agent working to it.
How to stay ahead
Being ready before you find the right home means your broker can act on the same day a suitable deal appears, rather than days later when it may have gone.
Quick tips
- Get your paperwork ready now: payslips, bank statements, ID and proof of deposit, so an application can go in quickly.
- Get an agreement in principle before you view seriously, so sellers and agents take your offer seriously.
- Know your full costs: stamp duty, legal fees and moving costs, not just the deposit.
- Diarise your offer expiry date and share it with your solicitor on day one.
- Ask about extensions early: some lenders may extend an offer, but it is not automatic and may need fresh checks.
- Don't change jobs or take new credit mid-application without speaking to your adviser first.
