20 WESTHOUSE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the County Durham local authority area over time, sourced from the HPI. The two 20 WESTHOUSE AVENUE sales from December 2005 and November 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 December 2005 sale was for 254% above the HPI. So the extrapolation line tracks at 254% above the HPI over time, until the November 2021 sale, where it rises to 340% above the HPI. The line then continues to track at 340% above the HPI.

What might 20 WESTHOUSE AVENUE be worth now?
