A complete guide to property investment in Stone.
Last updated: 18 September 2025
Stone sits just outside Dartford and offers a mix of affordability and strong rental returns, making it an area that piques investor interest. The price-to-income ratio of 4.1 suggests that buying property here is relatively accessible compared to many parts of the South East. Meanwhile, the average rental yield of 6.7% is robust, and the current median asking rent for a 3-bedroom house of £2,225 highlights the area's rental demand.
Liquidity is reasonable, with properties spending an average of 63 days on the market, and there is no median discount on achieved prices, indicating sellers are generally getting what they ask for. While the capital growth over 1 year of -1.9% has changed, the 3-year growth of 7.0% still shows a positive trend, which tempers any short-term concerns.

Stone’s fundamentals remain appealing for buy-to-let investors, especially given the strong rental yields of 6.7% and ongoing demand from families and couples. The 3-year annualised growth of 2.3% offers some reassurance for those with a medium-term horizon, even if the most recent year has seen a change in direction.
Affordability is likely to continue supporting demand, and the absence of a median discount on achieved prices points to a market where buyers and sellers are largely in agreement. Investors should watch for any shifts in local employment or demographic trends, but the current mix of rental demand and accessible pricing keeps Stone firmly on the radar for those seeking steady returns.
