51 BILLY LOWS LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hertsmere local authority area over time, sourced from the HPI. The two 51 BILLY LOWS LANE sales from December 2006 and October 2013 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 2006 sale was for 33% below the HPI. So the extrapolation line tracks at 33% below the HPI over time, until the October 2013 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 51 BILLY LOWS LANE be worth now?
