Diversification

A portfolio HMO mortgage is designed for landlords with multiple HMO properties, offering more flexible terms. These mortgages typically have lower rates and higher borrowing limits for experienced investors.

There is no single rule — portfolio products start from around 4+ mortgaged properties with some lenders, while others specialise at 10+ units. What matters is total portfolio rental income, aggregate LTV, and your experience. Some lenders offer portfolio underwriting (global affordability) rather than assessing each property in isolation, which can release more borrowing capacity across the book.
