6 BARNWELL CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The three 6 BARNWELL CLOSE sales between December 1995 and November 2003 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 April 2000 sale was for 35% above the HPI. So the extrapolation line tracks at 35% above the HPI over time, until the November 2003 sale, where it falls to 31% above the HPI. The line then continues to track at 31% above the HPI.

What might 6 BARNWELL CLOSE be worth now?
