11 CLOS ISLWYN 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 four 11 CLOS ISLWYN sales between April 2000 and April 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 2021 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the April 2024 sale, where it rises to 6% above the HPI. The line then continues to track at 6% above the HPI.

What might 11 CLOS ISLWYN be worth now?
