15 KINSBOURNE CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The two 15 KINSBOURNE CLOSE sales from August 2011 and April 2019 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 2011 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the April 2019 sale, where it falls to 45% below the HPI. The line then continues to track at 45% below the HPI.

What might 15 KINSBOURNE CLOSE be worth now?
