A complete guide to property investment in Erith.
Last updated: 18 September 2025
Erith sits on the edge of London, offering a mix of affordability and rental demand that catches the eye of investors looking for value outside the city centre. The area’s median price per square foot of £417 per sq ft is relatively accessible compared to much of London, making entry costs less daunting. Families dominate the local demographic (in the 98th percentile nationally), and the supply of owner-occupied homes is low (20th percentile), which keeps the private rental sector active. Liquidity is reasonable, with properties spending a median of 54 days on the market and a neutral gap between asking and achieved prices (£0 (the typical achieved discount)).

Erith’s outlook for the next year is mildly positive. The combination of strong rental yields of 6.9% and steady capital growth (5.3% in the last year) suggests the area is likely to remain attractive to buy-to-let investors. Family demand is likely to support rental values, while the price-to-income ratio of 6.2 and rent-to-income ratio of 34.1% keep affordability within reach for working households.
Liquidity should remain steady, with annual sales at 300 and median days on market at 54 days, so investors can expect reasonable exit options. While the high unemployment rate and reliance on the rental sector present risks, the fundamentals point to ongoing resilience in both sales and lettings.
