THE COTTAGE 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 two THE COTTAGE sales from August 2017 and March 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 2017 sale was for 68% above the HPI. So the extrapolation line tracks at 68% above the HPI over time, until the March 2023 sale, where it falls to 65% above the HPI. The line then continues to track at 65% above the HPI.

What might THE COTTAGE be worth now?

THE COTTAGE might now be worth an estimated £513,854.

This is based on house price inflation of 8.2%, between March 2023 and February 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 8.2% inflationary increase is applied to the most recent sale price for THE COTTAGE of £475,000 on 31st March 2023. For the value to have increased from £475,000 to £513,854 over the two years and one month to February 2025, the following assumptions must hold true:

• The value of THE COTTAGE has moved in line with the HPI for detached houses in the Caerphilly local authority area.
• The March 2023 sale price of £475,000 represented a fair market value for the property.
• The size, condition, and specification of THE COTTAGE has not materially changed since March 2023.
