A complete guide to property investment in Seaham.
Last updated: 18 September 2025
Seaham is a coastal town where affordability stands out, with a price-to-income ratio of 3.0 that puts it firmly in the accessible bracket for buyers. The local property market is relatively liquid, as homes spend an average of 42 days on the market — quicker than many neighbouring areas. Rental investors will notice strong rental yields of 5.8%, which are especially attractive in the top-performing postcode district, where yields reach 8.2%. The market has seen 1-year capital growth of 1.7%, but the longer-term picture is more muted, with 3-year annualised growth of -3.4%.

Looking ahead, Seaham’s property market is likely to remain attractive to yield-focused investors given the current median asking rent for a 3-bedroom house of £695 and for a 2-bedroom flat of £550. The affordability factor should continue to support buyer interest, especially with the median sale price for a 3-bedroom house at £165,000 and for a 2-bedroom flat at £70,000.
While capital growth has been subdued over the last three years, the relatively quick sales and steady rental demand offer reasons for optimism. Investors should watch local demographic shifts and employment trends, but for now, Seaham’s combination of affordability, yield and liquidity keeps it firmly on my radar.
