4 DERWENT CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 4 DERWENT CLOSE sales from July 2000 and July 2017 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 July 2000 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the July 2017 sale, where it falls to 20% below the HPI. The line then continues to track at 20% below the HPI.

What might 4 DERWENT CLOSE be worth now?
