11 THORNTON DENE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Bromley local authority area over time, sourced from the HPI. The three 11 THORNTON DENE sales between September 2001 and March 2025 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 February 2003 sale was for 61% below the HPI. So the extrapolation line tracks at 61% below the HPI over time, until the March 2025 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.

What might 11 THORNTON DENE be worth now?

This is based on house price inflation of 3.7%, between March 2025 and October 2025, for semi-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 3.7% inflationary increase is applied to the most recent sale price for 11 THORNTON DENE of £650,000 on 28th March 2025. For the value to have increased from £650,000 to £673,730 over the five months to October 2025, the following assumptions must hold true:
