131 PARK AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bromley local authority area over time, sourced from the HPI. The two 131 PARK AVENUE sales from March 2010 and February 2018 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 2010 sale was for 21% below the HPI. So the extrapolation line tracks at 21% below the HPI over time, until the February 2018 sale, where it rises to 12% below the HPI. The line then continues to track at 12% below the HPI.

What might 131 PARK AVENUE be worth now?

The 15.9% inflationary increase is applied to the most recent sale price for 131 PARK AVENUE of £800,000 on 9th February 2018. For the value to have increased from £800,000 to £926,897 over the seven years to February 2025, the following assumptions must hold true:
