21 MARION CRESCENT 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 21 MARION CRESCENT sales from June 2006 and February 2026 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 June 2006 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the February 2026 sale, where it falls to 42% below the HPI. The line then continues to track at 42% below the HPI.

What might 21 MARION CRESCENT be worth now?

This is based on house price inflation of 2.7%, between February 2026 and May 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 2.7% inflationary increase is applied to the most recent sale price for 21 MARION CRESCENT of £380,000 on 27th February 2026. For the value to have increased from £380,000 to £390,206 over the nine months to May 2026, the following assumptions must hold true:

• The value of 21 MARION CRESCENT has moved in line with the HPI for semi-detached houses in the Bromley local authority area.
• The February 2026 sale price of £380,000 represented a fair market value for the property.
