15 JOHNSONS FIELD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Milton Keynes local authority area over time, sourced from the HPI. The two 15 JOHNSONS FIELD sales from April 2004 and December 2018 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 April 2004 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the December 2018 sale, where it falls to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might 15 JOHNSONS FIELD be worth now?
