27 PENN GARDENS 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 two 27 PENN GARDENS sales from October 1999 and August 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 October 1999 sale was for 48% below the HPI. So the extrapolation line tracks at 48% below the HPI over time, until the August 2003 sale, where it rises to 39% below the HPI. The line then continues to track at 39% below the HPI.

What might 27 PENN GARDENS be worth now?
