Should you invest in Southborough?

Opportunities

  • The area’s strongest rental yields are in the top-performing district, where yields reach 5.3%, offering potential for above-average returns.
  • Steady capital growth, as shown by the 4.1% one-year and 10.4% three-year figures, could appeal to investors looking for long-term value.
  • The median asking rent for a two-bedroom flat is £1,825, which, combined with the moderate rent-to-income ratio of 24.3%, suggests a stable tenant base.

Risks

  • The market’s median discount of £3,000 (the typical achieved discount) may indicate some negotiation room, hinting at buyer caution or slower demand.
  • With a price-to-income ratio of 6.1, affordability could become a concern if local incomes do not keep pace with property values.
  • The area’s family-oriented population profile may limit demand for smaller flats or student lets, given the lower percentile for younger adults.

Outlook

Looking ahead, Southborough’s property market seems likely to remain steady, underpinned by its strong family demographic and balanced supply-demand dynamics. The annualised growth rate of 3.4% over three years points to a market that is neither overheated nor stagnant.

Rental demand should be sustained by the area’s moderate rent-to-income ratio of 24.3%, while the average days on market of 68 days suggests that liquidity is reasonable for both buyers and sellers. Investors should keep an eye on affordability, as the price-to-income ratio of 6.1 could start to weigh on demand if local wages do not keep up. Overall, I expect stable if unspectacular performance in both rental and sales markets over the next year.
