## Mortgage Overview: How FHL Mortgage Best Rates Interest Only Works
An FHL mortgage best rates interest only is a specialist buy-to-let product designed for properties let on a short-term basis to holidaymakers. Unlike standard BTL mortgages, FHL mortgages must meet HMRC’s definition of a furnished holiday let to qualify for certain tax benefits.
With an interest-only structure, landlords pay only the interest on the loan each month, keeping repayments lower and improving cash flow. The capital is repaid at the end of the term, often through property sale, refinancing, or savings.
### Key Features:
– Fixed, tracker, and variable rate options
– Available to individuals and limited companies
– Typically assessed on projected holiday rental income, not AST
– Higher yields due to short-term letting potential
– Tax-efficient if qualifying as an FHL under HMRC rules
### Who It’s For:
– First-time landlords entering the holiday let market
– Portfolio landlords diversifying into short-term lets
– Limited companies seeking tax efficiency
– Investors in high-tourism areas (e.g., Cornwall, Lake District)
FHL mortgages differ from standard residential mortgages in that they are underwritten based on projected holiday rental income rather than personal income or long-term tenancy agreements. Lenders may also require evidence of lettings history or holiday letting agency projections.
