## Single let mortgage for foreign nationals

A single let property, rented to one household under an Assured Shorthold Tenancy (AST), is generally regarded by UK lenders as the most straightforward investment type for foreign national mortgage applicants. Prior UK landlord experience is not usually required, making single lets a common entry point for overseas investors and first-time UK landlords.

Foreign nationals with established UK credit history or previous UK borrowing may qualify for tier-one foreign national mortgage products, which typically offer lower interest rates and higher loan-to-value limits. These products reflect the lower perceived risk associated with single let properties and are often the most competitively priced options available to overseas borrowers.

Lenders assess affordability based on a valuer’s opinion of market rent under an AST rather than the existing rental income. This approach ensures lending decisions are based on sustainable rental potential and standardised stress testing, helping foreign national borrowers understand how rental income is treated within the UK mortgage framework.
