What might MELLOW STACK be worth now?

MELLOW STACK might now be worth an estimated £1,018,260.

This is based on house price inflation of 16.4%, between March 2021 and May 2026, for detached houses, in the Buckinghamshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 16.4% inflationary increase is applied to the most recent sale price for MELLOW STACK of £875,000 on 31st March 2021. For the value to have increased from £875,000 to £1,018,260 over the four years and ten months to May 2026, the following assumptions must hold true:
