SIMDDE HIR 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 four SIMDDE HIR sales between August 2004 and July 2024 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 June 2019 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the July 2024 sale, where it rises to 66% above the HPI. The line then continues to track at 66% above the HPI.

What might SIMDDE HIR be worth now?

SIMDDE HIR might now be worth an estimated £523,166.

This is based on house price inflation of 5.7%, between July 2024 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 5.7% inflationary increase is applied to the most recent sale price for SIMDDE HIR of £495,000 on 3rd July 2024. For the value to have increased from £495,000 to £523,166 over the one year and five months to February 2025, the following assumptions must hold true:

• The value of SIMDDE HIR has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The July 2024 sale price of £495,000 represented a fair market value for the property.
• The size, condition, and specification of SIMDDE HIR has not materially changed since July 2024.
