CARTREF Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The two CARTREF sales from August 1999 and January 2020 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 1999 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the January 2020 sale, where it falls to 34% below the HPI. The line then continues to track at 34% below the HPI.

What might CARTREF be worth now?

CARTREF might now be worth an estimated £823,494.

This is based on house price inflation of 21.1%, between January 2020 and December 2024, for detached houses, in the St Albans local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 21.1% inflationary increase is applied to the most recent sale price for CARTREF of £680,000 on 22nd January 2020. For the value to have increased from £680,000 to £823,494 over the three years and one month to December 2024, the following assumptions must hold true:

• The value of CARTREF has moved in line with the HPI for detached houses in the St Albans local authority area.
• The January 2020 sale price of £680,000 represented a fair market value for the property.
• The size, condition, and specification of CARTREF has not materially changed since January 2020.
