Why buy-to-let mortgages for limited companies? This structure is often used by property investors seeking portfolio growth and potential tax planning efficiency.

How does a buy-to-let mortgage for a limited company work? The loan is usually provided to a special purpose vehicle (SPV) or incorporated company set up for property investment. Lenders review company structure, director details, and projected rental income before issuing terms. Repayments are commonly interest-only, with rental income expected to cover a set proportion of monthly costs. Standard valuation and legal checks apply, but underwriting also includes corporate considerations such as ownership structure and business classification. Eligibility criteria for limited company mortgages generally include requirements around company structure, shareholder composition, and director credit profiles. Many lenders prefer SPVs with property-related SIC codes. Applicants may need to show deposit funds, relevant experience, and acceptable credit history. Some lenders request company accounts or financial projections. New companies may face additional scrutiny, while others focus on asset strength and rental potential rather than trading history. How much can I borrow? Borrowing limits for limited company buy-to-let mortgages depend largely on projected rental income and lender affordability models. Rental coverage & stress testing are applied to ensure rental income can withstand higher interest rate scenarios. Typically, lenders require rental income to exceed mortgage payments by a margin of around 125% to 145%. Other factors include deposit size, property type, and overall portfolio exposure. Limits vary between first-time investors and experienced landlords with established portfolios.
