SEASPRAY 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 SEASPRAY sales from April 1998 and May 1999 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 April 1998 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the May 1999 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might SEASPRAY be worth now?

SEASPRAY might now be worth an estimated £324,032.

This is based on house price inflation of 359.6%, between May 1999 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 359.6% inflationary increase is applied to the most recent sale price for SEASPRAY of £70,500 on 13th May 1999. For the value to have increased from £70,500 to £324,032 over the 26 years and three months to February 2025, the following assumptions must hold true:

• The value of SEASPRAY has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The May 1999 sale price of £70,500 represented a fair market value for the property.
• The size, condition, and specification of SEASPRAY has not materially changed since May 1999.
