4 DEAN CLOSE 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 two 4 DEAN CLOSE sales from July 1999 and September 1999 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 July 1999 sale was for 40% below the HPI. So the extrapolation line tracks at 40% below the HPI over time, until the September 1999 sale, where it falls to 42% below the HPI. The line then continues to track at 42% below the HPI.

What might 4 DEAN CLOSE be worth now?
