1 CHATHAM STREET 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 1 CHATHAM STREET sales between May 1998 and August 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 June 2019 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the August 2024 sale, where it rises to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 1 CHATHAM STREET be worth now?

This is based on house price inflation of 4.5%, between August 2024 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 4.5% inflationary increase is applied to the most recent sale price for 1 CHATHAM STREET of £280,000 on 15th August 2024. For the value to have increased from £280,000 to £292,721 over the one year and five months to March 2025, the following assumptions must hold true:
