LLYS BACH is a very large extended detached house of 256m², built sometime before 1900, which could now be worth an estimated £470,864. It was last sold for £315,000 in May 2014, which was around 56% above the average May 2014 detached price in the Gwynedd local authority area. The most recent EPC inspection was November 2013, where the current energy rating was G, and the potential energy rating was D.
Land registry data shows two sales for LLYS BACH since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Gwynedd local authority area for the corresponding sale date. Both of the two LLYS BACH 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 |
---|---|---|---|
2014 30 MAY | £315,000 | £201,729 | ![]() 56% above HPI |
1998 27 NOV | £185,000 | £67,675 | ![]() 173% above HPI |
The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The two LLYS BACH sales from November 1998 and May 2014 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 November 1998 sale was for 173% above the HPI. So the extrapolation line tracks at 173% above the HPI over time, until the May 2014 sale, where it falls to 56% above the HPI. The line then continues to track at 56% above the HPI.
LLYS BACH might now be worth an estimated £470,864.
This is based on house price inflation of 49.5%, between May 2014 and February 2025, for detached houses, in the Gwynedd local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 49.5% inflationary increase is applied to the most recent sale price for LLYS BACH of £315,000 on 30th May 2014. For the value to have increased from £315,000 to £470,864 over the eleven years and three months to February 2025, the following assumptions must hold true:
