18 HIGHGROVE AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The three 18 HIGHGROVE AVENUE sales between September 2006 and November 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 February 2010 sale was for 67% above the HPI. So the extrapolation line tracks at 67% above the HPI over time, until the November 2019 sale, where it falls to 32% above the HPI. The line then continues to track at 32% above the HPI.

What might 18 HIGHGROVE AVENUE be worth now?
