Southborough offers a balanced property market with a strong presence of families, placing it in the 88th percentile for this demographic. The area has seen capital values change by 4.1% over the past year and by 10.4% over three years, which suggests steady long-term growth. The median price per square foot stands at £471 per sq ft, and the price-to-income ratio is 6.1, which is relatively moderate for the South East. Rental yields average 4.3%, with the top local district achieving yields of 5.3%.
Liquidity is reasonable, with properties spending an average of 68 days on the market and annual sales at 131. The market tends to favour buyers slightly, as the median achieved price is £3,000 (the typical achieved discount) below asking.

Looking ahead, Southborough’s property market seems likely to remain steady, underpinned by its strong family demographic and balanced supply-demand dynamics. The annualised growth rate of 3.4% over three years points to a market that is neither overheated nor stagnant.
Rental demand should be sustained by the area’s moderate rent-to-income ratio of 24.3%, while the average days on market of 68 days suggests that liquidity is reasonable for both buyers and sellers. Investors should keep an eye on affordability, as the price-to-income ratio of 6.1 could start to weigh on demand if local wages do not keep up. Overall, I expect stable if unspectacular performance in both rental and sales markets over the next year.
