ARCHFIELDS 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 ARCHFIELDS sales from August 2018 and February 2019 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 2018 sale was for 36% below the HPI. So the extrapolation line tracks at 36% below the HPI over time, until the February 2019 sale, where it falls to 41% below the HPI. The line then continues to track at 41% below the HPI.

What might ARCHFIELDS be worth now?

ARCHFIELDS might now be worth an estimated £605,828.

This is based on house price inflation of 26.2%, between February 2019 and April 2026, 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 26.2% inflationary increase is applied to the most recent sale price for ARCHFIELDS of £480,000 on 22nd February 2019. For the value to have increased from £480,000 to £605,828 over the six years and ten months to April 2026, the following assumptions must hold true:

• The value of ARCHFIELDS has moved in line with the HPI for detached houses in the Sevenoaks local authority area.
• The February 2019 sale price of £480,000 represented a fair market value for the property.
• The size, condition, and specification of ARCHFIELDS has not materially changed since February 2019.
