What might 24 CASTLEGATE be worth now?

24 CASTLEGATE might now be worth an estimated £142,195.

This is based on house price inflation of 3%, between September 2025 and July 2026, for semi-detached houses, in the South Kesteven local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3% inflationary increase is applied to the most recent sale price for 24 CASTLEGATE of £138,000 on 26th September 2025. For the value to have increased from £138,000 to £142,195 over the one year and two months to July 2026, the following assumptions must hold true:

• The value of 24 CASTLEGATE has moved in line with the HPI for semi-detached houses in the South Kesteven local authority area.
• The September 2025 sale price of £138,000 represented a fair market value for the property.
