FHL mortgages for properties in national parks often require additional documentation, including an accountant’s letter confirming the property meets HMRC’s FHL criteria. These mortgages differ from standard buy-to-let products due to seasonal income variations and stricter planning regulations in protected areas.
## Mortgage Overview
An FHL mortgage accountant letter national park is a specialist mortgage product designed for landlords purchasing or remortgaging a furnished holiday let in a UK national park. These areas—such as the Lake District, Peak District, and Snowdonia—are subject to tighter planning rules, making lender scrutiny more rigorous.
FHL mortgages are distinct from standard buy-to-let mortgages. They are assessed based on projected short-term rental income rather than long-term tenancy agreements. As such, lenders often require an accountant’s letter verifying that the property qualifies as an FHL under HMRC rules, including:
– Available for letting at least 210 days per year
– Actually let for at least 105 days annually
– Let on a short-term basis (no more than 31 consecutive days per tenancy)
Product types include:
– Fixed-rate mortgages (2, 5, or 10 years)
– Variable-rate mortgages (linked to lender SVR)
– Tracker mortgages (linked to Bank of England base rate)
These mortgages suit:
– First-time landlords entering the holiday let market
– Portfolio landlords expanding into short-term lets
– Limited companies investing in FHLs for tax efficiency
Lender appetite for FHLs remains strong in 2025, especially in high-demand tourist areas. However, properties in national parks may face additional scrutiny due to planning restrictions and conservation concerns.
