1 HELVETIA STREET Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Lewisham local authority area over time, sourced from the HPI. The two 1 HELVETIA STREET sales from December 2003 and July 2011 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 December 2003 sale was for 7% above the HPI. So the extrapolation line tracks at 7% above the HPI over time, until the July 2011 sale, where it falls to 4% above the HPI. The line then continues to track at 4% above the HPI.

What might 1 HELVETIA STREET be worth now?
