TREVALSA Price Paid vs. HPI Average

The below graph shows the average detached house price in the Woking local authority area over time, sourced from the HPI. The four TREVALSA sales between April 1998 and April 2014 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 October 2007 sale was for 28% below the HPI. So the extrapolation line tracks at 28% below the HPI over time, until the April 2014 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might TREVALSA be worth now?

TREVALSA might now be worth an estimated £698,524.

This is based on house price inflation of 44.8%, between April 2014 and December 2024, for detached houses, in the Woking local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 44.8% inflationary increase is applied to the most recent sale price for TREVALSA of £482,500 on 1st April 2014. For the value to have increased from £482,500 to £698,524 over the nine years and four months to December 2024, the following assumptions must hold true:

• The value of TREVALSA has moved in line with the HPI for detached houses in the Woking local authority area.
• The April 2014 sale price of £482,500 represented a fair market value for the property.
• The size, condition, and specification of TREVALSA has not materially changed since April 2014.
