What that means for a landlord
- Gross yield 4.2% (rent × 12 ÷ price) — rank 197 of 316 local authorities; the regional median is 4.4%. Net yield is lower once mortgage interest, insurance, maintenance and voids come off.
- Tenant affordability: referencing at 30× means a household income of about £21,660 a year for the average rent.
- EPC before 2030: 59% of EPCs lodged in Gwynedd over the last year were below band C — the level a rented home needs by 1 October 2030 — with 32% at D (EPC ratings in Gwynedd).
Lender maths on the averages. At a 5.5% stress rate and 145% rent cover — the common buy-to-let convention — the average rent of £722 supports a loan of about £108,639, which is 52.6% of the average price. That falls short of 75% loan-to-value, so a buyer of an average home here needs a larger deposit or a stronger rent to pass the stress test. Both numbers are conventions rather than rules — change them in the stress test.
