HAPPY VALLEY 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 HAPPY VALLEY sales from November 1996 and August 2022 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 November 1996 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the August 2022 sale, where it falls to 51% below the HPI. The line then continues to track at 51% below the HPI.

What might HAPPY VALLEY be worth now?

HAPPY VALLEY might now be worth an estimated £517,595.

This is based on house price deflation of 2.3%, between August 2022 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 2.3% deflationary decrease is applied to the most recent sale price for HAPPY VALLEY of £530,000 on 24th August 2022. For the value to have decreased from £530,000 to £517,595 over the three years and six months to February 2025, the following assumptions must hold true:

• The value of HAPPY VALLEY has moved in line with the HPI for detached houses in the Bromley local authority area.
• The August 2022 sale price of £530,000 represented a fair market value for the property.
• The size, condition, and specification of HAPPY VALLEY has not materially changed since August 2022.
