3 SUNNYDENE 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 three 3 SUNNYDENE AVENUE sales between May 2001 and December 2018 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 May 2018 sale was for 36% below the HPI. So the extrapolation line tracks at 36% below the HPI over time, until the December 2018 sale, where it rises to 5% above the HPI. The line then continues to track at 5% above the HPI.

What might 3 SUNNYDENE AVENUE be worth now?

This is based on house price inflation of 11.3%, between December 2018 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 11.3% inflationary increase is applied to the most recent sale price for 3 SUNNYDENE AVENUE of £870,000 on 21st December 2018. For the value to have increased from £870,000 to £968,523 over the six years to December 2024, the following assumptions must hold true:
