Homes bought and resold within 12 months made up just 1.5 percent of transactions across England and Wales in 2025, the lowest share in more than a decade, as stamp duty costs and weaker price growth cut the economics of flipping.
Analysis by Hamptons using HM Land Registry data found the number of flipped homes has fallen from 21,520 in 2016 to 10,570 in 2025. Average post-stamp duty gross profit dropped from £36,500 in 2015 to £16,390 last year, a fall of 55.1 percent.
For landlords and buy-to-let investors, the message is straightforward: quick-turn property strategies look less forgiving than they did before the second home surcharge and its later increase to 5 percent. The old assumption that a light refurb plus a resale would cover costs has become much harder to justify.
Stamp duty has eaten into short-term property profits
Hamptons said stamp duty accounted for 43 percent of gross profit on the average flip in 2025, equivalent to £12,400. Once refurbishment, finance and selling costs are added, many deals that look acceptable on paper are likely to become marginal or loss-making.
The regional split matters too. Returns have fallen hardest in the South, where price growth has been weaker and transaction costs are higher. London’s average post-stamp duty gross profit dropped to £35,720 in 2025, down 64.5 percent since 2015. In the South East it fell 78.4 percent to £9,900, while the South West dropped 80.3 percent to £6,560.
Landlord Knowledge has already tracked how higher stamp duty has pushed buy-to-let investment further north and how tax receipts from property transactions keep climbing. Hamptons’ latest analysis adds another consequence: tax pressure is not just changing where investors buy, but also whether shorter-term trading strategies stack up at all.
Cheaper properties still offer the best chance of a gain
Properties bought for less than £100,000 were the most likely to make a gross profit after stamp duty, with 86 percent doing so in 2025. That compared with just 28 percent of properties bought for more than £350,000.
This follows Landlord Knowledge’s recent coverage of investors chasing stronger regional returns, which again pointed to lower-priced markets offering a better balance of yield and growth. The latest figures suggest that trend is not just about rental income. It also affects the viability of exit strategies for landlords who refurbish and sell.
The wider warning is that landlords should be careful not to confuse a gross profit calculation with a workable investment. In a market with higher taxes, slower price growth and tighter borrowing conditions, short-term property plays need much more margin for error than they did a decade ago. HM Land Registry publishes the underlying transaction information through its official Land Registry pages.
What this means for landlords
- If you’re planning a flip: Rework the numbers with higher stamp duty, selling costs and a more cautious resale assumption.
- If you’re weighing hold versus sell: Stronger long-term rental income may now look safer than a fast turnaround.
- Watch for: Better value in lower-priced regional markets where transaction costs take a smaller bite.
- Bottom line: Flipping is still possible, but the easy profits have largely gone.
Editor’s view
The tax system has changed the arithmetic. Plenty of investors still talk as if the pre-surcharge market is only just around the corner, but the numbers say otherwise. For landlords, that makes patience and income discipline more valuable than trying to force a quick exit.
