20 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 four 20 PORTMARNOCK WAY sales between December 2005 and March 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 May 2015 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the March 2018 sale, where it falls to 27% below the HPI.
