21 NEATH ROAD 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 two 21 NEATH ROAD sales from September 2006 and July 2011 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 September 2006 sale was for 47% above the HPI. So the extrapolation line tracks at 47% above the HPI over time, until the July 2011 sale, where it rises to 85% above the HPI. The line then continues to track at 85% above the HPI.

What might 21 NEATH ROAD be worth now?

21 NEATH ROAD might now be worth an estimated £294,491.

This is based on house price inflation of 90%, between July 2011 and December 2024, 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 90% inflationary increase is applied to the most recent sale price for 21 NEATH ROAD of £155,000 on 1st July 2011. For the value to have increased from £155,000 to £294,491 over the twelve years and seven months to December 2024, the following assumptions must hold true:

• The value of 21 NEATH ROAD has moved in line with the HPI for semi-detached houses in the Neath Port Talbot local authority area.
• The July 2011 sale price of £155,000 represented a fair market value for the property.
• The size, condition, and specification of 21 NEATH ROAD has not materially changed since July 2011.
