HARVARD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sevenoaks local authority area over time, sourced from the HPI. The two HARVARD sales from June 1999 and July 2020 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 1999 sale was for 17% below the HPI. So the extrapolation line tracks at 17% below the HPI over time, until the July 2020 sale, where it rises to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might HARVARD be worth now?

HARVARD might now be worth an estimated £792,557.

This is based on house price inflation of 13.2%, between July 2020 and December 2024, for detached houses, in the Sevenoaks local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 13.2% inflationary increase is applied to the most recent sale price for HARVARD of £700,000 on 23rd July 2020. For the value to have increased from £700,000 to £792,557 over the three years and seven months to December 2024, the following assumptions must hold true:

• The value of HARVARD has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The July 2020 sale price of £700,000 represented a fair market value for the property.
• The size, condition, and specification of HARVARD has not materially changed since July 2020.
