1 BLACKWELL HILL Price Paid vs. HPI Average

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The five 1 BLACKWELL HILL sales between December 2000 and May 2022 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 2017 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the May 2022 sale, where it rises to 20% below the HPI. The line then continues to track at 20% below the HPI.

What might 1 BLACKWELL HILL be worth now?
