22 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 22 PORTMARNOCK WAY sales between March 2006 and August 2024 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 2014 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the August 2024 sale, where it rises to 21% below the HPI.
