Buy-to-Let Mortgages for Portfolio Landlords & HMOs
Once you're holding several rental properties or managing an HMO, lending gets more specialist — high-street banks often step back, and the right lender needs to understand your whole portfolio, not just the property in front of them. Sadi's Commercial Finance arranges unregulated buy-to-let finance for portfolio landlords, HMOs and multi-unit blocks across the UK.
Who it's for: landlords with four or more mortgaged rental properties (classed as portfolio landlords), HMO operators, and investors holding multi-unit freehold blocks (MUFBs).
How it works: we assess your portfolio, structure (personal, limited company or SPV) and goals, then source lenders comfortable with complex cases the high street won't consider — including HMOs and multi-unit blocks.
What makes portfolio and HMO lending different
- Portfolio landlords (four or more mortgaged properties) are assessed on their whole portfolio, not just the property being financed
- HMOs require specialist lenders comfortable with licensing and multiple tenancies
- Most lending in this space is unregulated, since the properties are investments rather than the borrower's home — giving more flexibility, but making lender choice and structure especially important
- Good preparation — a clear portfolio schedule and cash flow — makes applications significantly smoother
Why use Sadi's Commercial Finance
As an NACFB member specialising in unregulated commercial and investment finance, we know which lenders actively want portfolio and HMO business, and how to present a portfolio so it stacks up under scrutiny — avoiding the dead-end applications that cost landlords time.
Case study
A professional landlord with a growing portfolio refinanced an unencumbered three-unit residential investment block in South East England, securing a £950,000 interest-only mortgage on a 5-year fixed rate. The refinance released capital for further acquisitions while the lender's flexible approach to portfolio income kept the process moving — completing within 18 working days.
What counts as a portfolio landlord?
Holding four or more mortgaged rental properties makes you a portfolio landlord, at which point lenders assess your whole portfolio rather than just the property being financed.
Can I get a mortgage for an HMO?
Yes — specialist lenders finance HMOs and multi-unit freehold blocks, though criteria around licensing, room count and management are more detailed than standard buy-to-let.
Should I hold my portfolio personally or through a limited company?
Many portfolio landlords use an SPV (a limited company set up to hold property), which can offer tax and planning advantages — lenders are very comfortable with this structure, though the right choice depends on your circumstances.
