9 UPPER HARTWELL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three 9 UPPER HARTWELL sales between March 1999 and December 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 December 2006 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the December 2020 sale, where it falls to 36% below the HPI. The line then continues to track at 36% below the HPI.

What might 9 UPPER HARTWELL be worth now?
