18 HIGH STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Kesteven local authority area over time, sourced from the HPI. The two 18 HIGH STREET sales from May 1996 and August 2024 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 May 1996 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the August 2024 sale, where it rises to 18% below the HPI. The line then continues to track at 18% below the HPI.

What might 18 HIGH STREET be worth now?

18 HIGH STREET might now be worth an estimated £302,440.

This is based on house price inflation of 2.5%, between August 2024 and June 2025, for 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 2.5% inflationary increase is applied to the most recent sale price for 18 HIGH STREET of £295,000 on 8th August 2024. For the value to have increased from £295,000 to £302,440 over the one year and two months to June 2025, the following assumptions must hold true:

• The value of 18 HIGH STREET has moved in line with the HPI for detached houses in the South Kesteven local authority area.
• The August 2024 sale price of £295,000 represented a fair market value for the property.
• The size, condition, and specification of 18 HIGH STREET has not materially changed since August 2024.
