18 TREGARON AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Portsmouth local authority area over time, sourced from the HPI. The three 18 TREGARON AVENUE sales between April 2007 and December 2014 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 August 2007 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the December 2014 sale, where it rises to 55% above the HPI. The line then continues to track at 55% above the HPI.

What might 18 TREGARON AVENUE be worth now?
