A complete guide to property investment in Longfield.
Last updated: 10 January 2026
Longfield, New Ash Green and Hartley are established villages in the South East that offer a stable, largely owner-occupied housing market. The area’s housing stock is dominated by family homes, with a population that skews older — reflected by a population aged 60 and over in the 91st percentile. Owner-occupation is very high, sitting in the 93rd percentile, while private renting is rare, in only the 5th percentile. The typical three-bedroom house is marketed at £495,000, while two-bedroom flats are listed for £285,000. Rental demand is steady but not overheated, with average yields of 3.9% and three-bedroom house rents at £1,850.
Liquidity is reasonable, with properties spending about 55 days on the market and a median sale discount of £3,750 (the typical achieved discount). Affordability is moderate, with a price-to-income ratio of 7.7 and rent-to-income at 31.7%.

Looking ahead, the area’s fundamentals suggest stability rather than rapid growth. Owner-occupation will likely continue to dominate, with private renting remaining a small part of the market. The older demographic may lead to gradual turnover of housing stock, but the steady presence of families and professionals points to ongoing demand for well-maintained homes.
Given the 206 annual sales and average time on market of 55 days, liquidity should remain reasonable. Investors should expect moderate returns, with capital growth annualised over three years at 1.0% and average yields of 3.9%, rather than dramatic price movement. The outlook is best suited to investors seeking stable, long-term income over speculative gains.
