21 WAUN STERW Price Paid vs. HPI Average

The below graph shows the average detached house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The two 21 WAUN STERW sales from July 2022 and May 2023 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 July 2022 sale was for 27% above the HPI. So the extrapolation line tracks at 27% above the HPI over time, until the May 2023 sale, where it rises to 31% above the HPI. The line then continues to track at 31% above the HPI.

What might 21 WAUN STERW be worth now?

This is based on house price inflation of 4.2%, between May 2023 and February 2025, for detached houses, in the Neath Port Talbot local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 4.2% inflationary increase is applied to the most recent sale price for 21 WAUN STERW of £314,000 on 19th May 2023. For the value to have increased from £314,000 to £327,155 over the two years and three months to February 2025, the following assumptions must hold true:

• The value of 21 WAUN STERW has moved in line with the HPI for detached houses in the Neath Port Talbot local authority area.
• The May 2023 sale price of £314,000 represented a fair market value for the property.
