18 LLYS CASTELL 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 four 18 LLYS CASTELL sales between August 2001 and September 2022 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 October 2006 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the September 2022 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.

What might 18 LLYS CASTELL be worth now?

18 LLYS CASTELL might now be worth an estimated £277,170.

This is based on house price inflation of 2.7%, between September 2022 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 2.7% inflationary increase is applied to the most recent sale price for 18 LLYS CASTELL of £270,000 on 30th September 2022. For the value to have increased from £270,000 to £277,170 over the one year and nine months to December 2024, the following assumptions must hold true:

• The value of 18 LLYS CASTELL has moved in line with the HPI for detached houses in the Neath Port Talbot local authority area.
• The September 2022 sale price of £270,000 represented a fair market value for the property.
