21 WALNUT TREE ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Hounslow local authority area over time, sourced from the HPI. The three 21 WALNUT TREE ROAD sales between November 1999 and October 2007 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 October 2001 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the October 2007 sale, where it falls to 31% below the HPI. The line then continues to track at 31% below the HPI.

What might 21 WALNUT TREE ROAD be worth now?

This is based on house price inflation of 76.6%, between October 2007 and December 2024, for semi-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 76.6% inflationary increase is applied to the most recent sale price for 21 WALNUT TREE ROAD of £260,000 on 19th October 2007. For the value to have increased from £260,000 to £459,056 over the sixteen years and ten months to December 2024, the following assumptions must hold true:
