11 CASTLE STREET 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 11 CASTLE STREET sales from July 1999 and March 2024 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 July 1999 sale was for 88% above the HPI. So the extrapolation line tracks at 88% above the HPI over time, until the March 2024 sale, where it falls to 56% above the HPI. The line then continues to track at 56% above the HPI.

What might 11 CASTLE STREET be worth now?

This is based on house price inflation of 9%, between March 2024 and February 2025, 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 9% inflationary increase is applied to the most recent sale price for 11 CASTLE STREET of £230,000 on 8th March 2024. For the value to have increased from £230,000 to £250,618 over the one year and one month to February 2025, the following assumptions must hold true:
