17 KNIGHTSWELL 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 17 KNIGHTSWELL CLOSE sales from February 2014 and May 2022 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 February 2014 sale was for 51% below the HPI. So the extrapolation line tracks at 51% below the HPI over time, until the May 2022 sale, where it rises to 48% below the HPI. The line then continues to track at 48% below the HPI.
