28 DERWEN DEG Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The three 28 DERWEN DEG sales between November 1998 and September 2005 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 December 2002 sale was for 58% above the HPI. So the extrapolation line tracks at 58% above the HPI over time, until the September 2005 sale, where it rises to 67% above the HPI. The line then continues to track at 67% above the HPI.

What might 28 DERWEN DEG be worth now?

28 DERWEN DEG might now be worth an estimated £269,152.

This is based on house price inflation of 76.5%, between September 2005 and February 2025, for semi-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 76.5% inflationary increase is applied to the most recent sale price for 28 DERWEN DEG of £152,500 on 30th September 2005. For the value to have increased from £152,500 to £269,152 over the twenty years and seven months to February 2025, the following assumptions must hold true:

• The value of 28 DERWEN DEG has moved in line with the HPI for semi-detached houses in the Neath Port Talbot local authority area.
• The September 2005 sale price of £152,500 represented a fair market value for the property.
