What sits behind the figures

Prices across Southampton moved +25.0% over ten years on the UK House Price Index.

Employee jobs across Southampton moved −1.7% from 2015 to 2024 (ONS Business Register and Employment Survey).

47% of the energy performance certificates lodged across Southampton's postcode districts are below band C (152,590 certificates). Clarity measures areas rather than individual homes, so this is the share of the local stock likely to need energy-efficiency work before it meets a band C standard, not a survey of any one property.

A buy-to-let at £205,000 pays £11,850 in Stamp Duty Land Tax, including the 5% surcharge on additional homes.

The five-year forecast quoted above (Savills, South East) is a regional figure for South East as a whole, not a forecast for Southampton, and Clarity does not rank on it.
