143 ALTWOOD ROAD 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 143 ALTWOOD ROAD sales between October 2002 and September 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 April 2012 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the September 2018 sale, where it rises to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 143 ALTWOOD ROAD be worth now?
