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 GRAIG Y FFOREST sales from August 2014 and January 2017 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 August 2014 sale was for 26% above the HPI. So the extrapolation line tracks at 26% above the HPI over time, until the January 2017 sale, where it falls to 22% above the HPI. The line then continues to track at 22% above the HPI.
21 GRAIG Y FFOREST might now be worth an estimated £301,039.
This is based on house price inflation of 58.4%, between January 2017 and December 2024, 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 58.4% inflationary increase is applied to the most recent sale price for 21 GRAIG Y FFOREST of £189,995 on 12th January 2017. For the value to have increased from £189,995 to £301,039 over the six years and one month to December 2024, the following assumptions must hold true:
