13 TROWLOCK AVENUE 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 13 TROWLOCK AVENUE sales from February 2003 and May 2014 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 February 2003 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the May 2014 sale, where it rises to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might 13 TROWLOCK AVENUE be worth now?

13 TROWLOCK AVENUE might now be worth an estimated £2,205,703.

This is based on house price inflation of 33.8%, between May 2014 and February 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 33.8% inflationary increase is applied to the most recent sale price for 13 TROWLOCK AVENUE of £1,648,200 on 23rd May 2014. For the value to have increased from £1,648,200 to £2,205,703 over the eleven years and three months to February 2025, the following assumptions must hold true:
