40 MARLBOROUGH AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hillingdon local authority area over time, sourced from the HPI. The four 40 MARLBOROUGH AVENUE sales between August 1998 and June 2014 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 December 2006 sale was for 7% above the HPI. So the extrapolation line tracks at 7% above the HPI over time, until the June 2014 sale, where it falls to 18% below the HPI. The line then continues to track at 18% below the HPI.

What might 40 MARLBOROUGH AVENUE be worth now?

This is based on house price inflation of 50.7%, between June 2014 and December 2024, for detached houses, in the Hillingdon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 50.7% inflationary increase is applied to the most recent sale price for 40 MARLBOROUGH AVENUE of £499,500 on 12th June 2014. For the value to have increased from £499,500 to £752,895 over the nine years and six months to December 2024, the following assumptions must hold true:
