17 PORTMAN CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Dartford local authority area over time, sourced from the HPI. The three 17 PORTMAN CLOSE sales between June 1997 and October 2023 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 August 2001 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the October 2023 sale, where it rises to 19% above the HPI. The line then continues to track at 19% above the HPI.

What might 17 PORTMAN CLOSE be worth now?
