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 11 LLYS CASTELL sales between January 2001 and July 2014 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 2005 sale was for 74% above the HPI. So the extrapolation line tracks at 74% above the HPI over time, until the July 2014 sale, where it falls to 67% above the HPI. The line then continues to track at 67% above the HPI.
11 LLYS CASTELL might now be worth an estimated £422,805.
This is based on house price inflation of 69.1%, between July 2014 and June 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 69.1% inflationary increase is applied to the most recent sale price for 11 LLYS CASTELL of £249,995 on 18th July 2014. For the value to have increased from £249,995 to £422,805 over the eleven years and one month to June 2025, the following assumptions must hold true:
