22 DERWENT AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Harrow local authority area over time, sourced from the HPI. The two 22 DERWENT AVENUE sales from June 2006 and April 2012 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 June 2006 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the April 2012 sale, where it rises to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might 22 DERWENT AVENUE be worth now?

This is based on house price inflation of 76%, between April 2012 and February 2025, for detached houses, in the Harrow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 76% inflationary increase is applied to the most recent sale price for 22 DERWENT AVENUE of £580,000 on 27th April 2012. For the value to have increased from £580,000 to £1,020,558 over the thirteen years and two months to February 2025, the following assumptions must hold true:
