A commercial mortgage is, broadly, the business equivalent of a home loan: borrowing secured against property that a company either trades from or holds as an investment. It underpins the shops, offices, warehouses and hospitality venues we pass every day, as well as much of the commercial property let to tenants. This guide explains how commercial mortgages work in 2026, the difference between owner-occupied and investment deals, and what lenders look for. We are an education resource, so our aim is to help you understand your options before you take regulated advice.
What a commercial mortgage is
A commercial mortgage funds the purchase or refinance of property used for business purposes. Unlike residential lending, where decisions follow fairly standard templates, commercial deals are assessed case by case. The lender looks at the property, the borrower and the plan for the money, then shapes the terms, deposit and rate to fit. That flexibility is a strength, because a well-presented case can be negotiated, but it also means outcomes vary widely and preparation pays off.
Owner-occupied and investment deals
Commercial mortgages fall into two broad camps, and understanding which you need is the starting point.
- Owner-occupied. Where a business buys the premises it trades from, the lender assesses the strength and profitability of the business, since its trading generates the money to repay the loan.
- Commercial investment. Where the property is let to tenants, the rental income is central, so the lender focuses on the quality and length of the lease and the reliability of the tenant.
- Mixed use. Some properties combine commercial and residential elements, and these are assessed on both fronts.
Getting the category right from the outset helps you approach the right lenders and present the strongest case.
How lenders assess your application
Because each deal is bespoke, lenders build a picture from several angles. They consider the property itself, its type, location and condition, and how easily it could be sold or re-let if needed. They look at affordability, whether through business profits or rental income, and they assess the borrower experience, financial history and deposit. A larger deposit reduces the lender risk and generally improves the terms on offer. Clear, well-organised accounts and a coherent business plan make a real difference to how an application is received.
Rates, terms and repayment
Commercial mortgages come with a wider range of structures than residential ones. Rates may be fixed for a period or variable, and terms can be shorter than a typical home loan. Repayment can be on a capital-and-interest basis, which clears the debt over time, or interest-only, which keeps payments lower but leaves the capital to be repaid or refinanced later. Fees, including arrangement and valuation costs, tend to be more significant than on residential deals, so it is important to weigh the total cost rather than the headline rate alone.
Getting the right advice
Commercial finance is one of the areas where independent, whole-of-market advice earns its keep. Because terms are negotiable and lenders differ markedly in their appetite for particular sectors and property types, a broker who knows the market can often secure options and pricing that would be hard to find alone. Alongside that, sound accountancy and, where relevant, legal advice help ensure the deal is structured sensibly for tax and liability. Taking time to prepare and to seek the right guidance usually more than repays the effort.
Interest rates, lender appetite and sector confidence all move with the wider economy, and each affects what a commercial mortgage costs and how easily it can be arranged. Our Commercial and Business Finance news section follows these shifts and explains what they mean for businesses and investors, so you can time and structure your next deal with current information.
