The growing popularity of setting up a limited company for buy-to-let investments has reshaped the property finance landscape. With advantages such as increased borrowing potential and tax efficiencies, limited companies—often structured as Special Purpose Vehicles (SPVs)—are now the go-to for many property investors.
Choosing the right mortgage lender is crucial to maximising these benefits. In this guide, we’ll explore the top five buy-to-let mortgage lenders for limited companies, highlighting their unique offerings, why they stand out, and how they cater to SPVs.
Why Lenders Prefer Limited Companies
Over recent years, lenders have tailored products specifically for limited companies. These products offer:
Favourable Affordability Calculations: Lenders assess rental income rather than personal income, often leading to higher borrowing amounts.
Full Mortgage Interest Deduction: Unlike individual landlords, SPVs can deduct 100% of mortgage interest as a business expense.
Streamlined Lending Criteria: SPVs with appropriate SIC codes (such as 68209 for letting properties) are easier to underwrite.
