Report also finds that share of flat sales continues to fall

Properties worth £2m or more and flats remain the hardest properties to sell, according to new research from TwentyCi, which found one in four (25%) £2m-plus homes that reached an outcome in the third quarter of 2026 went on to sell and only 41% of flats listed during the quarter were likely to find a buyer.

That compared to more than half (53.1%) of properties below the £2m mark. The high-value properties also took more than twice as long to find a buyer, with a median time to sale of 86 days, compared to 41 days for sub-£2m properties.

TwentyCi’s Property & Homemover Report – Q3 2026 found that flat sales continue to decline. The latest 41.2% figure is down from 44.2% in 2025 and 54.2% in 2022. Meanwhile, in London only 27.2% of flats in Inner London and 30.7% in Outer London were likely to sell.

Asking price cuts higher for premium properties

The report also found asking price cuts were higher for £2m-plus homes, which achieved 90.5% of their initial asking price, compared with 96.3% for properties below £2m. However, this is based on 27 completions in the quarter.

Colin Bradshaw, CEO of TwentyCi, said: “The housing market cannot be understood through headline transaction volumes or average property prices alone. Our latest research highlights how sharply the likelihood and speed of a sale can vary, with flats facing increasing challenges and properties at the top end of the market taking considerably longer to find buyers.

“For mortgage lenders, this reinforces the importance of understanding the dynamics of the individual property and its local market when assessing security. A valuation provides an essential benchmark, but insight into current supply, demand and selling times can add another valuable dimension to understanding the risks associated with a property.”
