29 CYPRESS 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 three 29 CYPRESS AVENUE sales between October 1998 and May 2018 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 June 2001 sale was for 40% below the HPI. So the extrapolation line tracks at 40% below the HPI over time, until the May 2018 sale, where it falls to 43% below the HPI. The line then continues to track at 43% below the HPI.

What might 29 CYPRESS AVENUE be worth now?
