ROCKBOURNE 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 ROCKBOURNE sales from June 1998 and August 2016 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 1998 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the August 2016 sale, where it rises to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might ROCKBOURNE be worth now?

ROCKBOURNE might now be worth an estimated £266,611.

This is based on house price inflation of 50.6%, between August 2016 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 50.6% inflationary increase is applied to the most recent sale price for ROCKBOURNE of £177,000 on 2nd August 2016. For the value to have increased from £177,000 to £266,611 over the nine years and six months to February 2025, the following assumptions must hold true:

• The value of ROCKBOURNE has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The August 2016 sale price of £177,000 represented a fair market value for the property.
• The size, condition, and specification of ROCKBOURNE has not materially changed since August 2016.
