HMO Licensing in Southampton

Should You Invest in Southampton as a Landlord?
Southampton offers excellent gross yields, with the best-performing 1-bed properties achieving 7.9%. With 2 universities, student demand provides a reliable tenant pipeline for HMO and standard lettings alike.
Key strengths: Above-average yields at accessible price points. Year-round student demand reduces void periods. Familiar SDLT regime for English investors.
Considerations: The stricter HMO licensing regime means higher compliance costs — factor licence fees and property standards into your budget. The 5% SDLT surcharge (since October 2024) adds to upfront costs. Always account for void periods, maintenance reserves, and Section 24 tax restrictions when calculating net returns.
