21A WALNUT TREE ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hounslow local authority area over time, sourced from the HPI. The four 21A WALNUT TREE ROAD sales between February 2001 and March 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 September 2014 sale was for 52% below the HPI. So the extrapolation line tracks at 52% below the HPI over time, until the March 2016 sale, where it rises to 49% below the HPI. The line then continues to track at 49% below the HPI.

What might 21A WALNUT TREE ROAD be worth now?

21A WALNUT TREE ROAD might now be worth an estimated £521,107.

This is based on house price inflation of 22.6%, between March 2016 and February 2025, for detached houses, in the Hounslow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 22.6% inflationary increase is applied to the most recent sale price for 21A WALNUT TREE ROAD of £425,000 on 31st March 2016. For the value to have increased from £425,000 to £521,107 over the nine years and one month to February 2025, the following assumptions must hold true:

• The value of 21A WALNUT TREE ROAD has moved in line with the HPI for detached houses in the Hounslow local authority area.
• The March 2016 sale price of £425,000 represented a fair market value for the property.
