Commercial Mortgages

At Flagstone, we offer independent, whole-of-market commercial mortgage advice, helping business owners and investors find solutions tailored to their circumstances. From the initial conversation through to completion, you’ll receive clear guidance and hands-on support at every stage.
What is a commercial mortgage?
A commercial mortgage is a loan secured against commercial or mixed-use property. It can be used to purchase new premises, refinance existing borrowing, or raise capital against property already owned.
Commercial mortgages are available for owner-occupied properties, where a business trades from the premises, as well as commercial investment properties that generate rental income. Applications are typically assessed based on both the property itself and the borrower’s financial position.
Is a commercial mortgage right for me?
A commercial mortgage may be suitable if you’re purchasing or refinancing business premises, investing in commercial property, or looking for a longer-term finance solution backed by property.
It’s often appropriate where borrowing needs are more complex than standard residential lending and where access to multiple lenders can make a meaningful difference to rates, terms, and flexibility.
Who should consider a commercial mortgage?
Commercial mortgages are commonly used by business owners purchasing premises they trade from, as well as by commercial property investors looking to expand or refinance their portfolios. They can also be suitable for limited companies, LLPs, and sole traders, including portfolio landlords moving into or growing within the commercial property market.
Commercial property values can fall as well as rise. Economic downturns, changing demand, or sector-specific challenges can reduce property value. If values fall below the outstanding mortgage balance, refinancing or selling can become more difficult.
Understanding commercial mortgages
Commercial mortgage arrangements vary widely, shaped by factors such as property use, income, and risk. Taking the time to understand the fundamentals helps ensure the right decisions are made early on.
How commercial mortgages work
Commercial mortgages are secured loans against commercial or mixed-use property. Loan terms can vary from shorter arrangements through to long-term funding, depending on the lender and property type.
Deposits are usually higher than for residential mortgages, and interest rates are set on a case-by-case basis. Affordability is assessed using factors such as rental income, business accounts, projected income, and overall financial strength. Loan-to-value limits and approval criteria vary between lenders.
Types of commercial mortgages
Commercial mortgages can be structured in different ways depending on how the property is used.
Owner-occupied commercial mortgages are designed for businesses purchasing premises they trade from.
Commercial investment mortgages are used to buy business properties let to tenants to generate rental income.
Interest-only commercial mortgages allow monthly payments to cover interest, with the capital repaid at the end of the term.
When a commercial mortgage may be suitable
A commercial mortgage may be appropriate when buying premises for your business, investing in commercial or mixed-use property, refinancing existing borrowing, releasing capital tied up in property, or restructuring finance to improve cash flow.
