17B KNOLL RISE 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 17B KNOLL RISE sales from September 2008 and July 2010 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 2008 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the July 2010 sale, which was also at 16% below the HPI.

What might 17B KNOLL RISE be worth now?

17B KNOLL RISE might now be worth an estimated £883,796.

This is based on house price inflation of 88.4%, between July 2010 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 88.4% inflationary increase is applied to the most recent sale price for 17B KNOLL RISE of £469,000 on 28th July 2010. For the value to have increased from £469,000 to £883,796 over the fifteen years and five months to February 2025, the following assumptions must hold true:

• The July 2010 sale price of £469,000 represented a fair market value for the property.
