Land registry data shows two sales for HAULFRYN since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Isle of Anglesey local authority area for the corresponding sale date. Both of the two HAULFRYN sales were for above the average price. The average price is sourced from the Office for National Statistics' House Price Index (HPI).
| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2025 7 OCT | £399,950 | £321,910 | 24% above HPI |
1997 10 FEB | £69,500 | £62,293 | 12% above HPI |
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 HAULFRYN sales from February 1997 and October 2025 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 February 1997 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the October 2025 sale, where it rises to 24% above the HPI. The line then continues to track at 24% above the HPI.

HAULFRYN might now be worth an estimated £411,092.
This is based on house price inflation of 2.8%, between October 2025 and April 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 2.8% inflationary increase is applied to the most recent sale price for HAULFRYN of £399,950 on 7th October 2025. For the value to have increased from £399,950 to £411,092 over the one year and six months to April 2026, the following assumptions must hold true:
