My buyer's mortgage was declined. What happens to my sale?

It is a horrible phone call to get. The sale felt done, and now the buyer's mortgage has been turned down. Take a breath, because a decline is a moment to slow down and ask one question, not to panic. Plenty of these sales still complete, just with a different lender.

Why do mortgages get declined so late in a sale?

A mortgage in principle is a lender's early estimate of what it might lend, based on a soft look at the buyer's finances. It is not a firm offer. The full application, with the property valuation and a hard credit check, comes later, and that is where a deal can be refused even after weeks of progress.

Right now this is more common than usual. Bank of England figures showed around 56,200 mortgage approvals for house purchase in May 2026, down about 11% on a year earlier, as lenders held their affordability checks tight. A decline is often about the lender's rules, not the buyer changing their mind.

Is a declined mortgage the same as a down-valuation?

No, and the difference matters. A down-valuation is when the lender's surveyor values your home below the price you agreed, so the lender will only lend against the lower figure. The buyer is not refused; there is simply a gap to bridge. A true decline is when the lender says no to the buyer, usually on affordability, credit, or the property itself.

What should I do when my buyer's mortgage is declined?

1. 1. Find out exactly why

   Ask your agent to get the real reason from the buyer or their broker. Affordability, credit, and valuation are three different problems with three different fixes and timelines.

2. 2. Set a clear, short deadline

   Give the buyer a fixed window, often one to two weeks, to secure an alternative mortgage in principle from another lender. A deadline keeps the sale moving without you having to threaten anything.

3. 3. Check if it was really a down-valuation

   If the issue is the valuation and not the buyer, gather recent sold prices for similar homes nearby so the buyer can appeal, or so you can decide whether to adjust the price.

4. 4. Keep your home quietly visible

   Ask your agent to keep the listing warm and note any backup interest. You are not being disloyal; you are protecting yourself while the buyer regroups.

5. 5. Hold off on irreversible steps

   Do not pay for searches you do not need yet, order removals, or fully commit to your onward purchase until the buyer's new lender has issued an offer.

6. 6. Remarket calmly if the deadline passes

   If there is no real progress by your deadline, put the home back on the market without drama. A clean relaunch beats waiting months on a buyer who cannot fund the purchase.

How do I protect myself while my buyer sorts it out?

The safest way to read a buyer is by what they have put in place, not what they promise. A buyer actively working with a broker on a fresh application is committed. A buyer going quiet is a warning sign.

Around a quarter of agreed UK sales fall through, and lending and chain problems are a meaningful slice of that. So the sensible move is to line up your own solicitor early, which is cheap and keeps momentum, while holding back the big spends and the decision to come fully off the market until the buyer is funded again.

A declined mortgage feels like the end. Nine times out of ten it is a reason to slow down and ask one question: why?
