CASIMIR Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hertsmere local authority area over time, sourced from the HPI. The two CASIMIR sales from August 2002 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 August 2002 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the August 2024 sale, where it falls to 44% below the HPI. The line then continues to track at 44% below the HPI.

What might CASIMIR be worth now?

CASIMIR might now be worth an estimated £644,458.

This is based on house price deflation of 0.9%, between August 2024 and December 2024, for detached houses, in the Hertsmere local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.9% deflationary decrease is applied to the most recent sale price for CASIMIR of £650,000 on 6th August 2024. For the value to have decreased from £650,000 to £644,458 over the eight months to December 2024, the following assumptions must hold true:

• The value of CASIMIR has moved in line with the HPI for detached houses in the Hertsmere local authority area.
• The August 2024 sale price of £650,000 represented a fair market value for the property.
• The size, condition, and specification of CASIMIR has not materially changed since August 2024.
