Snowdonia and the Llŷn Peninsula holiday let: price, break-even and rules
Gwynedd (Eryri/Snowdonia, Abersoch, Pwllheli, Barmouth, Porthmadog) has some of the strongest outdoor demand in the UK at a low average purchase price. It is also the most tightly regulated holiday-let market in Wales, which is the thing to model first.
Ranked 3 of 27 in the UK Break-Even Index. Average purchase price £204,974 (Gwynedd, July 2026).
Gwynedd UK HPI, July 2026. up 5.5% over 12 months.
£193 at 45% occupancy · £145 at 65%.
25% deposit, LTT (higher residential rates), £18,000 furnishing and £2,500 legal/survey.
14.1% of the average purchase price, before you take a penny of profit.
These are area averages, not a valuation. A cottage in a honeypot village will sit well above the figure; a market-town terrace can sit below it. Replace the price with the actual asking price in the Deal Checker.
What the number means
If you cannot evidence £164 a night at 55% occupancy, the average Snowdonia and the Llŷn Peninsula purchase does not break even.
That rate is after 18% management and 3% platform fees, £115 cleaning every four-night stay, and the fixed costs in the stated cost model. It is not a recommended nightly rate. It is the floor at which the mortgage and the bills are covered, with no owner profit and no void reserve beyond the occupancy assumption.
A typical Snowdonia and the Llŷn Peninsula listing that actually books at £204–£244 in peak weeks can still fail the year if shoulder and winter nights sit well below this floor.

Demand
Who actually books here.
Very high in the mountain villages and Abersoch, strong on the Cambrian coast. Walkers, climbers, surfers, Zip World and Portmeirion visitors, and a large north-west England and Midlands catchment.
Summer and Easter peak with a good autumn for walking. Winter is viable for mountain-led stays. Abersoch is more second-home than holiday-let in character.
Property types that fit: Slate and stone cottages and terraces in the villages, farmhouses in the valleys, and premium coastal houses in Abersoch. Many properties are listed or in conservation areas.
