TREFUSIS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Waverley local authority area over time, sourced from the HPI. The three TREFUSIS sales between April 1999 and May 2022 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 June 2007 sale was for 275% above the HPI. So the extrapolation line tracks at 275% above the HPI over time, until the May 2022 sale, where it falls to 230% above the HPI. The line then continues to track at 230% above the HPI.

What might TREFUSIS be worth now?

TREFUSIS might now be worth an estimated £2,999,420.

This is based on house price inflation of 1.7%, between May 2022 and December 2024, for detached houses, in the Waverley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.7% inflationary increase is applied to the most recent sale price for TREFUSIS of £2,950,000 on 16th May 2022. For the value to have increased from £2,950,000 to £2,999,420 over the one year and five months to December 2024, the following assumptions must hold true:

• The value of TREFUSIS has moved in line with the HPI for detached houses in the Waverley local authority area.
• The May 2022 sale price of £2,950,000 represented a fair market value for the property.
• The size, condition, and specification of TREFUSIS has not materially changed since May 2022.
