10 PORTMAN ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Birmingham local authority area over time, sourced from the HPI. The three 10 PORTMAN ROAD sales between November 2003 and August 2017 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 2010 sale was for 35% above the HPI. So the extrapolation line tracks at 35% above the HPI over time, until the August 2017 sale, where it rises to 40% above the HPI. The line then continues to track at 40% above the HPI.

What might 10 PORTMAN ROAD be worth now?
