13 CHATHAM Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The four 13 CHATHAM sales between October 1995 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 August 2018 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the September 2022 sale, where it rises to 38% above the HPI. The line then continues to track at 38% above the HPI.

What might 13 CHATHAM be worth now?

13 CHATHAM might now be worth an estimated £271,056.

This is based on house price inflation of 7.3%, between September 2022 and December 2024, for semi-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 7.3% inflationary increase is applied to the most recent sale price for 13 CHATHAM of £252,500 on 15th September 2022. For the value to have increased from £252,500 to £271,056 over the one year and nine months to December 2024, the following assumptions must hold true:

• The value of 13 CHATHAM has moved in line with the HPI for semi-detached houses in the Caerphilly local authority area.
• The September 2022 sale price of £252,500 represented a fair market value for the property.
• The size, condition, and specification of 13 CHATHAM has not materially changed since September 2022.
