20 AILSA ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Richmond upon Thames local authority area over time, sourced from the HPI. The two 20 AILSA ROAD sales from May 2014 and May 2016 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 2014 sale was for 103% above the HPI. So the extrapolation line tracks at 103% above the HPI over time, until the May 2016 sale, which was also at 103% above the HPI.

What might 20 AILSA ROAD be worth now?

20 AILSA ROAD might now be worth an estimated £3,576,745.

This is based on house price inflation of 21.2%, between May 2016 and July 2025, for detached houses, in the Richmond upon Thames local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 21.2% inflationary increase is applied to the most recent sale price for 20 AILSA ROAD of £2,950,000 on 26th May 2016. For the value to have increased from £2,950,000 to £3,576,745 over the eight years and ten months to July 2025, the following assumptions must hold true:

• The value of 20 AILSA ROAD has moved in line with the HPI for detached houses in the Richmond upon Thames local authority area.
• The May 2016 sale price of £2,950,000 represented a fair market value for the property.
