Land registry data shows two sales for 11 MAES GERAINT since 1st January 1995. The below table shows the price paid for the two sales, along with the average semi-detached price in the Isle of Anglesey local authority area for the corresponding sale date. Both of the two 11 MAES GERAINT sales were for below 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 |
|---|---|---|---|

2004 21 MAY | £70,000 | £99,861 | 30% below HPI |
The below graph shows the average semi-detached house price in the Isle of Anglesey local authority area over time, sourced from the HPI. The two 11 MAES GERAINT sales from May 2004 and November 2017 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 May 2004 sale was for 30% below the HPI. So the extrapolation line tracks at 30% below the HPI over time, until the November 2017 sale, where it rises to 10% below the HPI. The line then continues to track at 10% below the HPI.

11 MAES GERAINT might now be worth an estimated £193,788.
This is based on house price inflation of 49.1%, between November 2017 and April 2026, for semi-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 49.1% inflationary increase is applied to the most recent sale price for 11 MAES GERAINT of £130,000 on 24th November 2017. For the value to have increased from £130,000 to £193,788 over the nine years and seven months to April 2026, the following assumptions must hold true:
