17 MAYALS GREEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The three 17 MAYALS GREEN sales between July 2008 and November 2019 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 January 2019 sale was for 80% above the HPI. So the extrapolation line tracks at 80% above the HPI over time, until the November 2019 sale, where it rises to 102% above the HPI. The line then continues to track at 102% above the HPI.
