30 FIRMIN AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Maidstone local authority area over time, sourced from the HPI. The two 30 FIRMIN AVENUE sales from December 2000 and January 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 2000 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the January 2020 sale, where it falls to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might 30 FIRMIN AVENUE be worth now?
