SIRAWEL Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Isle of Anglesey local authority area over time, sourced from the HPI. The four SIRAWEL sales between July 2001 and May 2023 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 2006 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the May 2023 sale, where it rises to 19% below the HPI. The line then continues to track at 19% below the HPI.

What might SIRAWEL be worth now?

SIRAWEL might now be worth an estimated £165,746.

This is based on house price inflation of 6.9%, between May 2023 and February 2025, for semi-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 6.9% inflationary increase is applied to the most recent sale price for SIRAWEL of £155,000 on 9th May 2023. For the value to have increased from £155,000 to £165,746 over the two years and three months to February 2025, the following assumptions must hold true:

• The value of SIRAWEL has moved in line with the HPI for semi-detached houses in the Isle of Anglesey local authority area.
• The May 2023 sale price of £155,000 represented a fair market value for the property.
• The size, condition, and specification of SIRAWEL has not materially changed since May 2023.
