4 PENDARREN 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 4 PENDARREN sales from December 2002 and October 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% below the HPI. So the extrapolation line tracks at 58% below the HPI over time, until the October 2005 sale, where it rises to 39% below the HPI. The line then continues to track at 39% below the HPI.

What might 4 PENDARREN be worth now?

4 PENDARREN might now be worth an estimated £149,784.

This is based on house price inflation of 74.2%, between October 2005 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 74.2% inflationary increase is applied to the most recent sale price for 4 PENDARREN of £86,000 on 7th October 2005. For the value to have increased from £86,000 to £149,784 over the eighteen years and ten months to December 2024, the following assumptions must hold true:

• The value of 4 PENDARREN has moved in line with the HPI for detached houses in the Neath Port Talbot local authority area.
• The October 2005 sale price of £86,000 represented a fair market value for the property.
• The size, condition, and specification of 4 PENDARREN has not materially changed since October 2005.
