TREMALAW 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 TREMALAW sales from September 1996 and June 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 September 1996 sale was for 52% above the HPI. So the extrapolation line tracks at 52% above the HPI over time, until the June 2014 sale, where it rises to 59% above the HPI. The line then continues to track at 59% above the HPI.

What might TREMALAW be worth now?

TREMALAW might now be worth an estimated £500,731.

This is based on house price inflation of 59.5%, between June 2014 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 59.5% inflationary increase is applied to the most recent sale price for TREMALAW of £314,000 on 27th June 2014. For the value to have increased from £314,000 to £500,731 over the eleven years and four months to February 2025, the following assumptions must hold true:

• The value of TREMALAW has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The June 2014 sale price of £314,000 represented a fair market value for the property.
• The size, condition, and specification of TREMALAW has not materially changed since June 2014.
