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 1 CORNISH ROW sales from September 1999 and November 2019 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 1999 sale was for 85% above the HPI. So the extrapolation line tracks at 85% above the HPI over time, until the November 2019 sale, where it rises to 103% above the HPI. The line then continues to track at 103% above the HPI.
1 CORNISH ROW might now be worth an estimated £507,163.
This is based on house price inflation of 37.1%, between November 2019 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 37.1% inflationary increase is applied to the most recent sale price for 1 CORNISH ROW of £370,000 on 18th November 2019. For the value to have increased from £370,000 to £507,163 over the six years and nine months to February 2025, the following assumptions must hold true:
