4 MAES GWYN 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 two 4 MAES GWYN sales from May 2006 and June 2010 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 May 2006 sale was for 59% above the HPI. So the extrapolation line tracks at 59% above the HPI over time, until the June 2010 sale, where it falls to 37% above the HPI. The line then continues to track at 37% above the HPI.

What might 4 MAES GWYN be worth now?

4 MAES GWYN might now be worth an estimated £270,845.

This is based on house price inflation of 90.7%, between June 2010 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 90.7% inflationary increase is applied to the most recent sale price for 4 MAES GWYN of £142,000 on 4th June 2010. For the value to have increased from £142,000 to £270,845 over the fifteen years and four months to February 2025, the following assumptions must hold true:

• The value of 4 MAES GWYN has moved in line with the HPI for semi-detached houses in the Caerphilly local authority area.
• The June 2010 sale price of £142,000 represented a fair market value for the property.
