43 DERRY DOWNS 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 two 43 DERRY DOWNS sales from March 1999 and July 2005 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 1999 sale was for 56% below the HPI. So the extrapolation line tracks at 56% below the HPI over time, until the July 2005 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might 43 DERRY DOWNS be worth now?

This is based on house price inflation of 131.9%, between July 2005 and April 2026, 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 131.9% inflationary increase is applied to the most recent sale price for 43 DERRY DOWNS of £295,000 on 15th July 2005. For the value to have increased from £295,000 to £684,218 over the 21 years and three months to April 2026, the following assumptions must hold true:
