4 TY ISAF Price Paid vs. HPI Average

The below graph shows the average detached house price in the Caerphilly local authority area over time, sourced from the HPI. The three 4 TY ISAF sales between August 2013 and January 2023 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 August 2022 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the January 2023 sale, where it falls to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might 4 TY ISAF be worth now?

This is based on house price inflation of 3.9%, between January 2023 and March 2025, for detached houses, in the Caerphilly local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3.9% inflationary increase is applied to the most recent sale price for 4 TY ISAF of £262,500 on 30th January 2023. For the value to have increased from £262,500 to £272,743 over the one year and ten months to March 2025, the following assumptions must hold true:
