33 SWALLOW CLOSE 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 three 33 SWALLOW CLOSE sales between February 1996 and November 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 December 2009 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the November 2018 sale, where it falls to 5% above the HPI. The line then continues to track at 5% above the HPI.

What might 33 SWALLOW CLOSE be worth now?
