The buy to let market has evolved significantly in recent years, with lenders applying stricter affordability rules, stress testing and deposit requirements. This makes expert guidance more important than ever, particularly for landlords with multiple properties, complex income, limited company structures or specialist investment strategies.

What Are Buy to Let Mortgages?

Buy to let mortgages are loans specifically designed for purchasing property that will be rented out to tenants. Unlike residential mortgages, lenders assess both the borrower’s personal circumstances and the expected rental income from the property.

Most buy to let mortgages are arranged on an interest only basis, allowing landlords to keep monthly payments lower while maximising rental yield. However, repayment options are also available depending on your investment strategy.

Lenders view buy to let mortgages differently from standard residential borrowing because the property is considered an investment asset. As a result, lender criteria, deposit requirements and affordability calculations are usually stricter.

AIMS NI helps landlords understand these differences and compare suitable mortgage options across the market.
