11 CASTLEMAINE 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 11 CASTLEMAINE AVENUE sales from December 2017 and January 2020 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 December 2017 sale was for 23% above the HPI. So the extrapolation line tracks at 23% above the HPI over time, until the January 2020 sale, where it rises to 32% above the HPI. The line then continues to track at 32% above the HPI.

What might 11 CASTLEMAINE AVENUE be worth now?

This is based on house price inflation of 18.9%, between January 2020 and August 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 18.9% inflationary increase is applied to the most recent sale price for 11 CASTLEMAINE AVENUE of £1,075,000 on 21st January 2020. For the value to have increased from £1,075,000 to £1,278,319 over the four years and five months to August 2025, the following assumptions must hold true:
