TREVONEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Three Rivers local authority area over time, sourced from the HPI. The three TREVONEN sales between March 1999 and February 2015 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 November 2012 sale was for 112% above the HPI. So the extrapolation line tracks at 112% above the HPI over time, until the February 2015 sale, where it falls to 99% above the HPI. The line then continues to track at 99% above the HPI.

What might TREVONEN be worth now?

TREVONEN might now be worth an estimated £2,282,023.

This is based on house price inflation of 36.2%, between February 2015 and December 2024, for detached houses, in the Three Rivers local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 36.2% inflationary increase is applied to the most recent sale price for TREVONEN of £1,675,000 on 19th February 2015. For the value to have increased from £1,675,000 to £2,282,023 over the eight years and two months to December 2024, the following assumptions must hold true:

• The value of TREVONEN has moved in line with the HPI for detached houses in the Three Rivers local authority area.
• The February 2015 sale price of £1,675,000 represented a fair market value for the property.
• The size, condition, and specification of TREVONEN has not materially changed since February 2015.
