The below graph shows the average terraced house price in the Hounslow local authority area over time, sourced from the HPI. The two 40 WILTON AVENUE sales from January 2000 and April 2019 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 January 2000 sale was for 134% above the HPI. So the extrapolation line tracks at 134% above the HPI over time, until the April 2019 sale, where it rises to 177% above the HPI. The line then continues to track at 177% above the HPI.

40 WILTON AVENUE might now be worth an estimated £1,641,309.
This is based on house price inflation of 20.2%, between April 2019 and March 2026, for terraced 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 20.2% inflationary increase is applied to the most recent sale price for 40 WILTON AVENUE of £1,365,000 on 8th April 2019. For the value to have increased from £1,365,000 to £1,641,309 over the seven years and one month to March 2026, the following assumptions must hold true:
