28 THE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 28 THE AVENUE sales from October 2013 and May 2021 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 October 2013 sale was for 11% above the HPI. So the extrapolation line tracks at 11% above the HPI over time, until the May 2021 sale, where it falls to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might 28 THE AVENUE be worth now?
