15 HENDERSON GROVE 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 15 HENDERSON GROVE sales from November 2006 and September 2009 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 November 2006 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the September 2009 sale, where it rises to 32% below the HPI. The line then continues to track at 32% below the HPI.

What might 15 HENDERSON GROVE be worth now?

This is based on house price inflation of 107.5%, between September 2009 and February 2025, for detached houses, in the Bromley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 107.5% inflationary increase is applied to the most recent sale price for 15 HENDERSON GROVE of £345,000 on 29th September 2009. For the value to have increased from £345,000 to £715,853 over the sixteen years and seven months to February 2025, the following assumptions must hold true:
