15 LONGHOUSE BARN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The two 15 LONGHOUSE BARN sales from September 2004 and September 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 September 2004 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the September 2020 sale, where it rises to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 15 LONGHOUSE BARN be worth now?
