3 HEATHERSLADE CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The two 3 HEATHERSLADE CLOSE sales from October 2017 and December 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the October 2017 sale was for 126% above the HPI. So the extrapolation line tracks at 126% above the HPI over time, until the December 2025 sale, where it falls to 112% above the HPI. The line then continues to track at 112% above the HPI.

What might 3 HEATHERSLADE CLOSE be worth now?

3 HEATHERSLADE CLOSE might now be worth an estimated £447,178.

This is based on house price deflation of 1.2%, between December 2025 and May 2026, for semi-detached houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.2% deflationary decrease is applied to the most recent sale price for 3 HEATHERSLADE CLOSE of £452,500 on 12th December 2025. For the value to have decreased from £452,500 to £447,178 over the one year and seven months to May 2026, the following assumptions must hold true:

• The value of 3 HEATHERSLADE CLOSE has moved in line with the HPI for semi-detached houses in the Swansea local authority area.
• The December 2025 sale price of £452,500 represented a fair market value for the property.
