A complete guide to property investment in Harrow.
Last updated: 18 September 2025
Harrow sits in a part of London where property markets tend to move at their own pace, and recent figures show a mixed picture. The area has seen capital growth over three years at 3.3%, though the one-year figure has changed by -3.2%, a reminder that even in London, not every postcode is immune to short-term shifts. Families are a major presence here, sitting in the 94th percentile, and the private rental sector is especially strong, in the 87th percentile compared to the rest of Britain. Owner-occupation is less common than in many parts of the country, but that's par for the course in this part of London.
For investors, the median price per square foot stands at £537 per sq ft, and the price-to-income ratio is 7.6, so affordability is stretched but not out of the ordinary for London. Rents are robust, with the average yield at 5.5%, and the top local postcode district delivering yields of 7.3%.

The next twelve months in Harrow are likely to be steady rather than spectacular. With annualised growth over three years at 1.1%, the market has shown some resilience, but the recent one-year capital growth figure of -3.2% suggests that investors should not expect rapid gains.
Rental demand is expected to remain strong, thanks to the area's large family population and high proportion of private renters. Asking prices for a three-bedroom house are currently £625,000, with rents at £2,395, while two-bedroom flats are commanding £375,000 and rents of £1,825. Investors with a long-term outlook may find Harrow's stability and rental appeal reassuring, even if short-term growth is muted. Liquidity should hold up, but buyers and sellers alike may need to be pragmatic about pricing and negotiation.
