13 HARWELL CLOSE 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 13 HARWELL CLOSE sales from October 2002 and October 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 October 2002 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the October 2014 sale, where it rises to 4% below the HPI. The line then continues to track at 4% below the HPI.

What might 13 HARWELL CLOSE be worth now?

The 43.9% inflationary increase is applied to the most recent sale price for 13 HARWELL CLOSE of £610,000 on 10th October 2014. For the value to have increased from £610,000 to £877,996 over the nine years and ten months to December 2024, the following assumptions must hold true:
