3 PORTMARNOCK WAY 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 3 PORTMARNOCK WAY sales between October 2005 and November 2013 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 June 2007 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the November 2013 sale, where it falls to 46% below the HPI. The line then continues to track at 46% below the HPI.
