The below graph shows the average detached house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The three 15 DERWEN DEG sales between September 1998 and September 2009 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 May 2005 sale was for 61% above the HPI. So the extrapolation line tracks at 61% above the HPI over time, until the September 2009 sale, where it falls to 57% above the HPI. The line then continues to track at 57% above the HPI.

15 DERWEN DEG might now be worth an estimated £399,610.
This is based on house price inflation of 75.7%, between September 2009 and May 2026, 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 75.7% inflationary increase is applied to the most recent sale price for 15 DERWEN DEG of £227,500 on 8th September 2009. For the value to have increased from £227,500 to £399,610 over the seventeen years and four months to May 2026, the following assumptions must hold true:
