TROTTS HILL 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 TROTTS HILL sales from September 2019 and June 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 September 2019 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the June 2022 sale, where it rises to 25% above the HPI. The line then continues to track at 25% above the HPI.

What might TROTTS HILL be worth now?

TROTTS HILL might now be worth an estimated £1,184,552.

This is based on house price deflation of 0.9%, between June 2022 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 0.9% deflationary decrease is applied to the most recent sale price for TROTTS HILL of £1,195,000 on 10th June 2022. For the value to have decreased from £1,195,000 to £1,184,552 over the one year and six months to December 2024, the following assumptions must hold true:

• The value of TROTTS HILL has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The June 2022 sale price of £1,195,000 represented a fair market value for the property.
