Trading (owner-occupier) vs investment mortgages
The single most important distinction in commercial lending: are you buying premises to trade from, or to rent out? Here is what changes.
Written by Matt Vincent DipFA, CeMAP, CeRER, BSc · Published 25 June 2026 · Version 1.0 · 5 min readWhen you apply for a commercial mortgage, the very first thing a lender wants to know is how the loan will be repaid. That splits almost every case into one of two types.
Owner-occupier (trading) mortgage
This is for a business buying premises it will trade from itself, your shop, office, workshop, salon, café, surgery or unit. The mortgage is paid from the profits of your business.
Because repayment comes from trading, the lender focuses on your business: its accounts, its profitability, its track record, and whether it can comfortably afford the payments. A strong, established trading business with good accounts is attractive here, but not always necessary.
Investment mortgage
This is for buying a property to let out to tenants, you collect the rent, and the rent pays the mortgage. It is the commercial version of buy-to-let.
Here the lender focuses on the rental income: how much rent the property produces, how reliable the tenants are, and how long their leases run. Lenders usually want the rent to cover the mortgage payment with a comfortable margin to spare (often called rental cover or interest cover).
Side by side
| Owner-occupier (trading) | Investment | |
|---|---|---|
| Who uses it | A business buying its own premises | A landlord/investor letting to tenants |
| What repays the loan | Your business profits | Rent from tenants |
| Lender focuses on | Trading accounts & affordability | Rental income, tenants & leases |
| Often held in | Your trading company or your name | A separate company (an SPV) |
Not sure which you are? If you'll be running the business from the building, you're an owner-occupier. If someone else pays you rent to use it, you're an investor.
