129 CILMAENGWYN ROAD 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 129 CILMAENGWYN ROAD sales from April 2001 and September 2015 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 April 2001 sale was for 89% above the HPI. So the extrapolation line tracks at 89% above the HPI over time, until the September 2015 sale, where it falls to 71% above the HPI. The line then continues to track at 71% above the HPI.

What might 129 CILMAENGWYN ROAD be worth now?

This is based on house price inflation of 68.9%, between September 2015 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 68.9% inflationary increase is applied to the most recent sale price for 129 CILMAENGWYN ROAD of £250,000 on 2nd September 2015. For the value to have increased from £250,000 to £422,342 over the eight years and nine months to December 2024, the following assumptions must hold true:
