TREFAIR Price Paid vs. HPI Average

The below graph shows the average detached house price in the Isle of Anglesey local authority area over time, sourced from the HPI. The two TREFAIR sales from August 1995 and November 2001 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 1995 sale was for 111% above the HPI. So the extrapolation line tracks at 111% above the HPI over time, until the November 2001 sale, where it rises to 124% above the HPI. The line then continues to track at 124% above the HPI.

What might TREFAIR be worth now?

TREFAIR might now be worth an estimated £705,515.

This is based on house price inflation of 272.3%, between November 2001 and February 2025, for detached houses, in the Isle of Anglesey local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 272.3% inflationary increase is applied to the most recent sale price for TREFAIR of £189,500 on 16th November 2001. For the value to have increased from £189,500 to £705,515 over the 24 years and nine months to February 2025, the following assumptions must hold true:

• The value of TREFAIR has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The November 2001 sale price of £189,500 represented a fair market value for the property.
• The size, condition, and specification of TREFAIR has not materially changed since November 2001.
