---|---|---|---|

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 OAK HOUSE sales from September 2017 and March 2022 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 September 2017 sale was for 46% above the HPI. So the extrapolation line tracks at 46% above the HPI over time, until the March 2022 sale, where it falls to 26% above the HPI. The line then continues to track at 26% above the HPI.
OAK HOUSE might now be worth an estimated £315,232.
This is based on house price inflation of 12.6%, between March 2022 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 12.6% inflationary increase is applied to the most recent sale price for OAK HOUSE of £280,000 on 7th March 2022. For the value to have increased from £280,000 to £315,232 over the three years and one month to February 2025, the following assumptions must hold true:
