A complete guide to property investment in Mortlake.
Last updated: 18 September 2025
Mortlake sits in South West London with a profile that should catch the eye of investors who value a steady, established market. The area is dominated by families, which is clear from its position in the 86th percentile for family households, and its professional credentials are strong, with a degree-educated population in the 99th percentile and professionals and managers in the 98th percentile. The private rented sector is well represented, with a high percentile compared to the rest of Britain, though owner-occupation here is close to the national average for London. Typical asking prices reflect the area's appeal, with the current median asking sale price for a three-bedroom house at £1,050,000 and a two-bedroom flat at £542,500. Rents are similarly robust, with a three-bedroom house asking £3,925 and a two-bedroom flat at £2,175.

The next 12 months in Mortlake are likely to see continued stability, with capital growth over the past year at 3.1% and annualised three-year growth at 2.1%. The professional and family-friendly profile of the area should help underpin demand, particularly for larger homes and quality flats.
Rental yields are likely to remain competitive for London, especially in the top-performing postcode district (4.6%), and the private rental sector will continue to play a significant role. However, affordability challenges may temper price growth, as both sale and rental asking prices are already high relative to incomes. Investors should expect a market that prioritises stability and long-term value over rapid short-term gains.
