18 ELM 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 two 18 ELM AVENUE sales from May 2014 and March 2024 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 2014 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the March 2024 sale, where it falls to 20% below the HPI. The line then continues to track at 20% below the HPI.

What might 18 ELM AVENUE be worth now?

This is based on house price inflation of 1.5%, between March 2024 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 1.5% inflationary increase is applied to the most recent sale price for 18 ELM AVENUE of £720,000 on 21st March 2024. For the value to have increased from £720,000 to £731,123 over the three months to December 2024, the following assumptions must hold true:
