I'll have to sell for less than I paid. What are my options?

This is one of the most common worries in the market this autumn, and it is more manageable than it first looks. Start with two definitions.

A sale at a loss is a sale for less than you paid. Negative equity is when your home is worth less than the mortgage secured on it. Most people selling at a loss are not in negative equity, because their deposit and years of repayments sit between the two figures.

How common is selling at a loss right now?

The wider market explains why. Nationwide reported on 1 October 2026 that prices fell 0.2% in September, the fourth fall in five months. Zoopla's index the same day showed 5% more homes for sale than a year ago, 9% fewer sales agreed, and buyers paying about £150 a month more on their mortgage than at the start of the year.

Is it a loss, or am I in negative equity?

Put three numbers side by side: the realistic sale price, what you still owe including any early repayment charge, and your selling costs. The illustration below uses round figures, not market data, for a home bought at £300,000.

What are my options if I'm selling at a loss?

1. 1. Get the real number from more than one agent

   One valuation can be pitched high to win your instruction or low to win a quick sale. Several local opinions side by side show you the realistic range, and the range is what you plan around.

2. 2. Work out the gap that actually matters

   If you are buying again, compare your sale price with the price of your next home in today's market. A £15,000 loss on your sale can be offset if the home you are buying has also come down.

3. 3. Check your mortgage before you agree a price

   Ask your lender for a redemption figure, the early repayment charge if you leave now, and whether you can port your deal to the next home. Porting means moving your existing rate to a new property, subject to the lender's checks.

4. 4. Speak to your lender early if you owe more than the house is worth

   A sale in negative equity needs the lender's agreement, because the proceeds will not clear the mortgage. Some lenders will let a shortfall move onto a new mortgage; ask your lender or a mortgage broker before you accept an offer.

5. 5. Price for today's buyers, not for what you paid

   Your purchase price is on the public Land Registry record, and it does not change what a buyer will offer. A home priced to today's market sells; a home priced to recover the past tends to sit while buyers look elsewhere.

6. 6. Compare selling now with waiting or letting, on paper

   Staying put means no loss is made real, which is often the right answer if you do not need to move. Letting usually needs your lender's consent to let, plus landlord costs and tax, so price that option honestly before choosing it.

7. 7. Move in step with your buyer

   Read your buyer's commitment by what they have spent: a solicitor instructed, searches ordered, a mortgage application submitted. Hold back your own big commitments, such as coming fully off the market or committing to the next purchase, until theirs are in place.

What's normal, and what's a red flag?

A loss on paper is one number. The decision rests on three: what you owe, what you sell for, and what you buy next.

Should I wait for prices to recover instead?

Nobody can promise when prices will recover, and anyone who does is guessing. Waiting makes sense when you do not need to move and can afford to stay. It makes less sense when the move is needed for work, family or money, because the months spent waiting carry their own costs.

How do I stay in control?

Know your three numbers before you agree anything, and decide the lowest offer you would accept before the first one arrives. Then the market's mood stops setting your terms. You do.
