70 BILLY LOWS LANE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Hertsmere local authority area over time, sourced from the HPI. The two 70 BILLY LOWS LANE sales from March 2002 and November 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 March 2002 sale was for 46% above the HPI. So the extrapolation line tracks at 46% above the HPI over time, until the November 2014 sale, where it falls to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might 70 BILLY LOWS LANE be worth now?

The 40.2% inflationary increase is applied to the most recent sale price for 70 BILLY LOWS LANE of £495,000 on 17th November 2014. For the value to have increased from £495,000 to £693,809 over the nine years and eleven months to December 2024, the following assumptions must hold true:
