Once your home hits the market, timing becomes everything. Sell too quickly and you risk leaving money on the table; let it linger and buyers start to question why. New estate agent data suggests there’s a narrow moment when homes perform best — and it comes on day 11.

Properties sold around this point are more likely to meet, or even exceed, their asking price, while those that remain on the market for weeks can begin to lose value.

Analysis of 6,000 estate agent branches by HomeOwners Alliance’s Best Estate Agent Finder shows that homes sold in around 11 days typically achieve 100.4 per cent of their asking price — adding roughly £1,100 to the final sale on an average UK property.

But selling too fast can be just as costly. Homes sold in seven days or less achieved just 94 per cent of their asking price, leaving sellers almost £16,000 worse off.

The figures reveal a clear pattern: once a property sits on the market for more than a month, its value often begins to slide. After 30 days, sellers typically accept around 98 per cent of their asking price, dropping to 95.5 per cent by the three-month mark.

With the average UK home now selling for around £270,000, those small percentage shifts add up quickly. A home sold after one month typically loses £5,400, while a sale agreed after three months can mean a loss of £18,400.

What to Read Next

'Right now every pound matters to homeowners,' says Paula Higgins, founder and chief executive of HomeOwners Alliance. 'Our data shows there is a sweet spot when selling a home and that is around 11 days. This isn’t about rushing a sale, it’s about choosing the right agent.

'The agents who consistently sell in around 11 days are the ones achieving the best prices. When a home sits on the market for weeks, it is often a sign something needs to change.'

Want to sell on the all important 11th day? Follow these tips

1. Appoint a great estate agent

A good starting point is finding an agent. HomeOwners Alliance's Best Estate Agent Finder ranks local agents by how successful they are at selling quickly and securing the asking price.

2. Get your price right

The average asking price for a UK home fell by -0.1 per cent over the last year, according to Rightmove’s September House Price Index report. This shows sellers are trying to get it right first time in light of a hesitant housing market.

3. Instruct your conveyancing solicitor early

Choose your conveyancing solicitor early as soon as you decide to list your home, and start pulling paperwork together now if you want to secure a quick sale. Flag any potential issues now, rather than letting the vendor discover them.

4. Get your house ready for sale

If there are any issues that might come up in a survey and delay the move, consider fixing them now. Property experts say energy efficiency improvements are going to be more of a selling point this year, so getting an EPC early in the process will give you an advantage.

5. Choose the right buyer

Everyone wants to get the best price, but if you also want to sell quickly, then opt for a chain-free buyer who isn’t relying on selling their home to buy yours.
