4 THORNTON DENE 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 4 THORNTON DENE sales from September 2002 and October 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 September 2002 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the October 2018 sale, where it rises to 8% below the HPI. The line then continues to track at 8% below the HPI.

What might 4 THORNTON DENE be worth now?

This is based on house price inflation of 14%, between October 2018 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 14% inflationary increase is applied to the most recent sale price for 4 THORNTON DENE of £850,000 on 26th October 2018. For the value to have increased from £850,000 to £969,165 over the seven years and eight months to February 2025, the following assumptions must hold true:
