40 ONSLOW GARDENS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Croydon local authority area over time, sourced from the HPI. The two 40 ONSLOW GARDENS sales from December 1996 and October 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 December 1996 sale was for 41% above the HPI. So the extrapolation line tracks at 41% above the HPI over time, until the October 2024 sale, where it falls to 7% above the HPI. The line then continues to track at 7% above the HPI.
