SUMMERHILL 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 SUMMERHILL sales from March 1998 and October 2004 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 1998 sale was for 70% above the HPI. So the extrapolation line tracks at 70% above the HPI over time, until the October 2004 sale, where it falls to 65% above the HPI. The line then continues to track at 65% above the HPI.

What might SUMMERHILL be worth now?

SUMMERHILL might now be worth an estimated £1,835,830.

This is based on house price inflation of 133.1%, between October 2004 and June 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 133.1% inflationary increase is applied to the most recent sale price for SUMMERHILL of £787,500 on 20th October 2004. For the value to have increased from £787,500 to £1,835,830 over the 21 years and four months to June 2025, the following assumptions must hold true:

• The value of SUMMERHILL has moved in line with the HPI for detached houses in the Bromley local authority area.
• The October 2004 sale price of £787,500 represented a fair market value for the property.
• The size, condition, and specification of SUMMERHILL has not materially changed since October 2004.
