23 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 23 CHATHAM sales between September 1999 and September 2019 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 2006 sale was for 41% above the HPI. So the extrapolation line tracks at 41% above the HPI over time, until the September 2019 sale, where it falls to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might 23 CHATHAM be worth now?

23 CHATHAM might now be worth an estimated £253,785.

This is based on house price inflation of 42.6%, between September 2019 and February 2025, 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 42.6% inflationary increase is applied to the most recent sale price for 23 CHATHAM of £178,000 on 6th September 2019. For the value to have increased from £178,000 to £253,785 over the six years and seven months to February 2025, the following assumptions must hold true:

  • The value of 23 CHATHAM has moved in line with the HPI for semi-detached houses in the Caerphilly local authority area.
  • The September 2019 sale price of £178,000 represented a fair market value for the property.
  • The size, condition, and specification of 23 CHATHAM has not materially changed since September 2019.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
