BRYN CELYN 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 three BRYN CELYN sales between January 1998 and May 2007 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 2001 sale was for 17% below the HPI. So the extrapolation line tracks at 17% below the HPI over time, until the May 2007 sale, where it falls to 29% below the HPI. The line then continues to track at 29% below the HPI.

What might BRYN CELYN be worth now?

BRYN CELYN might now be worth an estimated £230,853.

This is based on house price inflation of 56%, between May 2007 and May 2026, 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 56% inflationary increase is applied to the most recent sale price for BRYN CELYN of £148,000 on 25th May 2007. For the value to have increased from £148,000 to £230,853 over the nineteen years to May 2026, the following assumptions must hold true:

  • The value of BRYN CELYN has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
  • The May 2007 sale price of £148,000 represented a fair market value for the property.
  • The size, condition, and specification of BRYN CELYN has not materially changed since May 2007.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
