1 PORTLAND AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Swindon local authority area over time, sourced from the HPI. The three 1 PORTLAND AVENUE sales between June 1998 and May 2012 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 May 2002 sale was for 50% below the HPI. So the extrapolation line tracks at 50% below the HPI over time, until the May 2012 sale, where it falls to 57% below the HPI. The line then continues to track at 57% below the HPI.

What might 1 PORTLAND AVENUE be worth now?
