Four Out of Five Homes That Sell Never Drop Their Price. What That Tells You About Selling in Clapham

There is a flat on a road off the Common that has been sitting on Rightmove since spring. Nice flat. Good road. Nothing wrong with it at all, except the number on the front of it. A vendor I met last week asked me why it still had not gone, and the honest answer is the one nobody wants to hear at a valuation: it launched at a price the market did not believe, and every week since has been spent slowly proving that.

Some numbers landed on LinkedIn this week that make the point better than I can. Data from Sprift, covering 710,729 homes that came onto the UK market since 1 January 2026: only 238,105 of them have had a sale agreed. That is a third. Two out of every three sellers who launched this year are still waiting.

Now the part that should change how you think about your asking price. Of the 238,105 that did sell, 80.08% sold without a single price reduction, and they did it in an average of 28 days. The 20% that needed a reduction took an average of 64 days to get a sale agreed. Same market, same month, same buyers. More than double the time, and a lower price at the end of it.

Down here the pattern is identical. Across SW4 in June there were 136 homes on the market and 40 of them found a buyer. The flats sitting on the market carried a median asking price of £525,000; the flats that actually got agreed did so at a median of £475,000. On average an SW4 home took 52 days to go under offer, which is quicker than the national 59 - our market is not slow, it is just unforgiving of a punchy number.

Here is what that means in practice if you are selling in Clapham, Balham, Stockwell or Abbeville Village this autumn. Your first two to three weeks are the whole ballgame. That is when every buyer already registered and hunting sees your flat for the first time, when the portal alerts fire, and when your viewing diary is at its fullest. Price it right and you are choosing between offers while the launch buzz is live. Price it 8% high to "test the market" and those same buyers scroll past, you get the trickle rather than the flood, and eight weeks later you reduce to the number you should have started at - only now every buyer can see how long it has been sitting and treats you accordingly. The reduction does not fix the problem. It advertises it.

My take, and I will say it to any vendor who asks: never let anyone value your home on what you want it to be worth, including me. Value it on the last three genuinely comparable sales on your street or the one next to it, then decide whether you want to sell or you want to advertise. Testing the market is not a free option. It costs you five weeks, your best buyers, and usually more money than the reduction you were trying to avoid.

Are you sitting on a home that has been out there too long, or thinking about launching this autumn and wondering where the number should be? Tell me the road and I will tell you straight what I think it will actually sell for. Drop me a line at jeroen@claphampropertyblog.com or call 07837 093554.
