17 BRYN DERWEN 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 four 17 BRYN DERWEN sales between June 1996 and February 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 August 1999 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the February 2015 sale, where it rises to 6% below the HPI. The line then continues to track at 6% below the HPI.

What might 17 BRYN DERWEN be worth now?

17 BRYN DERWEN might now be worth an estimated £236,986.

This is based on house price inflation of 72.4%, between February 2015 and June 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 72.4% inflationary increase is applied to the most recent sale price for 17 BRYN DERWEN of £137,500 on 3rd February 2015. For the value to have increased from £137,500 to £236,986 over the nine years and eight months to June 2025, the following assumptions must hold true:

• The value of 17 BRYN DERWEN has moved in line with the HPI for detached houses in the Neath Port Talbot local authority area.
• The February 2015 sale price of £137,500 represented a fair market value for the property.
• The size, condition, and specification of 17 BRYN DERWEN has not materially changed since February 2015.
