Looking ahead, Keston’s property market is likely to continue its steady trajectory, with owner-occupation remaining the dominant tenure. The strong presence of families and professionals should underpin demand for houses, especially given the current asking prices for a 3-bedroom house (£692,500) and a 2-bedroom flat (£559,950).
Rental yields in the top-performing postcode district (5.3%) and stable rents suggest that investors can expect consistent, if unspectacular, returns. However, affordability pressures and a limited rental market may cap short-term growth. Expect liquidity to remain moderate, with properties taking around 93 days to sell. In short, Keston looks set to reward patience and a long-term view rather than quick profits.
