21 ILSTON WAY 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 two 21 ILSTON WAY sales from August 2016 and July 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 August 2016 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the July 2024 sale, where it falls to 31% below the HPI. The line then continues to track at 31% below the HPI.
