CWMAMMAN HOUSE 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 three CWMAMMAN HOUSE sales between July 2000 and September 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 December 2004 sale was for 82% above the HPI. So the extrapolation line tracks at 82% above the HPI over time, until the September 2019 sale, where it falls to 40% above the HPI. The line then continues to track at 40% above the HPI.

What might CWMAMMAN HOUSE be worth now?

CWMAMMAN HOUSE might now be worth an estimated £350,135.

This is based on house price inflation of 40.6%, between September 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 40.6% inflationary increase is applied to the most recent sale price for CWMAMMAN HOUSE of £249,000 on 20th September 2019. For the value to have increased from £249,000 to £350,135 over the six years and seven months to February 2025, the following assumptions must hold true:

• The value of CWMAMMAN HOUSE has moved in line with the HPI for detached houses in the Neath Port Talbot local authority area.
• The September 2019 sale price of £249,000 represented a fair market value for the property.
