12 HILLSIDE GARDENS 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 12 HILLSIDE GARDENS sales from January 2016 and September 2020 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 2016 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the September 2020 sale, where it rises to 23% below the HPI. The line then continues to track at 23% below the HPI.

What might 12 HILLSIDE GARDENS be worth now?

This is based on house price inflation of 9.8%, between September 2020 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 9.8% inflationary increase is applied to the most recent sale price for 12 HILLSIDE GARDENS of £645,000 on 25th September 2020. For the value to have increased from £645,000 to £707,943 over the three years and nine months to December 2024, the following assumptions must hold true:
