21 WINDMILL AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Epsom and Ewell local authority area over time, sourced from the HPI. The two 21 WINDMILL AVENUE sales from September 2012 and June 2013 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 September 2012 sale was for 43% below the HPI. So the extrapolation line tracks at 43% below the HPI over time, until the June 2013 sale, where it rises to 12% below the HPI. The line then continues to track at 12% below the HPI.

What might 21 WINDMILL AVENUE be worth now?

This is based on house price inflation of 68.2%, between June 2013 and February 2025, for detached houses, in the Epsom and Ewell local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 68.2% inflationary increase is applied to the most recent sale price for 21 WINDMILL AVENUE of £500,000 on 20th June 2013. For the value to have increased from £500,000 to £841,215 over the twelve years and four months to February 2025, the following assumptions must hold true:
