Should you invest in Mortlake?

Opportunities

  • Rental yields are relatively strong for London, with an average of 4.4% and the top postcode district in the area reaching 4.6%.
  • The area has seen capital growth over both one and three years (3.1% and 6.5% respectively), suggesting resilience and steady demand.
  • Liquidity is reasonable, with annual sales at 243 and a typical property spending 60 days on the market before selling.

Risks

  • Affordability is stretched, with a price-to-income ratio of 10.9 and a rent-to-income ratio of 30.0%, which is high even by London standards.
  • The difference between achieved and asking prices, at a median of £25,000 (the typical achieved discount), could indicate some negotiation is needed or that buyers are cautious.
  • The area has a lower proportion of younger renters (population aged 20-30 in the 8th percentile), which could limit certain rental demand segments.

Outlook

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.
