TIFFANYS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The two TIFFANYS sales from September 2006 and January 2012 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 September 2006 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the January 2012 sale, where it rises to 203% above the HPI. The line then continues to track at 203% above the HPI.

What might TIFFANYS be worth now?

TIFFANYS might now be worth an estimated £2,521,589.

This is based on house price inflation of 65.4%, between January 2012 and December 2024, for detached houses, in the Buckinghamshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 65.4% inflationary increase is applied to the most recent sale price for TIFFANYS of £1,525,000 on 16th January 2012. For the value to have increased from £1,525,000 to £2,521,589 over the eleven years and one month to December 2024, the following assumptions must hold true:

• The value of TIFFANYS has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The January 2012 sale price of £1,525,000 represented a fair market value for the property.
• The size, condition, and specification of TIFFANYS has not materially changed since January 2012.
