21 PORTRUSH DRIVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Kesteven local authority area over time, sourced from the HPI. The three 21 PORTRUSH DRIVE sales between August 2000 and May 2012 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 August 2004 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the May 2012 sale, where it falls to 32% below the HPI. The line then continues to track at 32% below the HPI.

What might 21 PORTRUSH DRIVE be worth now?
