What might 17 COPSESIDE be worth now?

17 COPSESIDE might now be worth an estimated £643,361.

This is based on house price inflation of 18%, between June 2021 and July 2026, for semi-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 18% inflationary increase is applied to the most recent sale price for 17 COPSESIDE of £545,000 on 24th June 2021. For the value to have increased from £545,000 to £643,361 over the four years and eleven months to July 2026, the following assumptions must hold true:

  • The value of 17 COPSESIDE has moved in line with the HPI for semi-detached houses in the Sevenoaks local authority area.
  • The June 2021 sale price of £545,000 represented a fair market value for the property.
  • The size, condition, and specification of 17 COPSESIDE has not materially changed since June 2021.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
