10 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 two 10 BRYN DERWEN sales from May 2011 and September 2017 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 2011 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the September 2017 sale, where it falls to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might 10 BRYN DERWEN be worth now?

10 BRYN DERWEN might now be worth an estimated £278,948.

This is based on house price inflation of 50.4%, between September 2017 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 50.4% inflationary increase is applied to the most recent sale price for 10 BRYN DERWEN of £185,500 on 14th September 2017. For the value to have increased from £185,500 to £278,948 over the six years and nine months to December 2024, the following assumptions must hold true:

• The value of 10 BRYN DERWEN has moved in line with the HPI for detached houses in the Neath Port Talbot local authority area.
• The September 2017 sale price of £185,500 represented a fair market value for the property.
