THE GARDEN HOUSE 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 three THE GARDEN HOUSE sales between April 1995 and October 2015 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 August 2000 sale was for 376% above the HPI. So the extrapolation line tracks at 376% above the HPI over time, until the October 2015 sale, where it falls to 288% above the HPI. The line then continues to track at 288% above the HPI.

What might THE GARDEN HOUSE be worth now?

THE GARDEN HOUSE might now be worth an estimated £3,668,736.

This is based on house price inflation of 33.4%, between October 2015 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 33.4% inflationary increase is applied to the most recent sale price for THE GARDEN HOUSE of £2,750,000 on 16th October 2015. For the value to have increased from £2,750,000 to £3,668,736 over the eight years and ten months to December 2024, the following assumptions must hold true:

• The value of THE GARDEN HOUSE has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The October 2015 sale price of £2,750,000 represented a fair market value for the property.
• The size, condition, and specification of THE GARDEN HOUSE has not materially changed since October 2015.
