11 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 11 TROWLOCK AVENUE sales from April 2009 and September 2018 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 April 2009 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the September 2018 sale, where it rises to 31% above the HPI. The line then continues to track at 31% above the HPI.

What might 11 TROWLOCK AVENUE be worth now?

11 TROWLOCK AVENUE might now be worth an estimated £2,133,461.

This is based on house price inflation of 6.9%, between September 2018 and December 2024, 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 6.9% inflationary increase is applied to the most recent sale price for 11 TROWLOCK AVENUE of £1,995,000 on 20th September 2018. For the value to have increased from £1,995,000 to £2,133,461 over the five years and nine months to December 2024, the following assumptions must hold true:

  • The value of 11 TROWLOCK AVENUE has moved in line with the HPI for detached houses in the Richmond upon Thames local authority area.
  • The September 2018 sale price of £1,995,000 represented a fair market value for the property.
  • The size, condition, and specification of 11 TROWLOCK AVENUE has not materially changed since September 2018.
