A commercial mortgage, sometimes referred to as a business mortgage, is a type of loan secured against a property that’s used for business purposes rather than as your domestic residence.
If you own, run, or invest in a business, a commercial mortgage could be the key to buying new premises, refinancing an existing loan, or unlocking capital from a property you already own. These mortgages are a standard financing option for companies of all sizes, from small start-ups purchasing their first office space to established corporations expanding into new locations.
This guide explains commercial mortgages and how they differ from residential ones.
What is a commercial mortgage used for?
A commercial mortgage can be used for a variety of business-related purposes, including:
- Purchasing commercial property such as offices, retail shops, warehouses, factories, or leisure facilities.
- Refinancing an existing commercial loan to secure better interest rates or repayment terms.
- Property investment aimed at generating rental income from commercial tenants.
- Mixed-use properties where a single building combines both commercial and residential elements, such as a shop with flats above.
- Development projects, including buying land or funding construction for business purposes.
While a commercial mortgage is similar to a home mortgage, there are important differences in purpose, process, and costs.
How commercial and residential mortgages differ
Both residential and commercial mortgages involve borrowing money to buy property and repaying it over time. However, they don’t function the same because they meet separate needs and pose different levels of risk for lenders.
Below are the main differences.
- Purpose
- Residential mortgage: Used to buy a home you will live in yourself (or for a family member).
- Commercial mortgage: Used for property primarily intended for business purposes – either for your own business use or as a rental/investment property.
- Property type
Residential mortgages are almost exclusively for houses and flats. Commercial mortgages cover a much wider range of property types, including:
- Office buildings
- Retail units and shopping centres
- Industrial premises like factories or warehouses
- Hospitality venues such as hotels, pubs, or restaurants
- Development land
- Mixed-use premises (for example, a shop with living accommodation above)
- Lending criteria
For residential mortgages, lenders focus heavily on:
- Your personal credit history
- Your employment status and income
- Your debt-to-income ratio
For commercial mortgages, lenders will also consider:
- The potential income the property can generate (for example, through tenants or business activity)
- Your business’s financial performance and stability
- Your experience in running or managing similar businesses or properties
- The quality and location of the property being used as security
- Repayment terms
Residential mortgages can stretch up to 35–40 years, giving borrowers time to spread the cost and keep monthly payments lower. Commercial mortgages typically have shorter repayment terms, usually between ten and 25 years. Some lenders will offer terms up to 25 years.
- Loan amounts
Commercial properties are often more expensive than residential homes, which means the loan amounts can be significantly larger. Even so, the amount you can borrow will be closely linked to the value of the property and the projected business income it can generate.
- Loan-to-value (LTV) ratio
LTV refers to the percentage of the property’s value that the lender is willing to finance.
- Residential mortgages can go up to 95% LTV, meaning you could buy with just a 5% deposit. Some lenders even offer 100% home-buying mortgages.
- The maximum LTV for a commercial mortgage is usually 75%, meaning you’ll typically need at least a 25% deposit.
If you have a new business or the property has a higher risk profile (for example, a specialised building type or a location with low demand), the lender may operate at a lower LTV.
- Interest rates
Interest rates for commercial mortgages are generally higher than for residential mortgages.
Your rate will depend on several factors, including the loan amount, term length, your credit history, the business’s financial health, and the perceived stability of the property’s value.
- Regulations
Residential mortgages in the UK are regulated by the Financial Conduct Authority (FCA), which provides borrowers with strong consumer protection.
Commercial mortgages are not generally regulated by the FCA, which gives lenders more flexibility in structuring deals but means borrowers have fewer formal protections. This factor makes it even more important to work with a broker who can ensure the terms are fair and competitive.
Pros and cons of commercial mortgages
Like any form of borrowing, commercial mortgages have advantages and drawbacks.
Advantages:
- Offers long-term stability compared to renting commercial premises.
- Enables you to build equity in the property over time.
- May provide more favourable rates than other types of business borrowing (e.g., unsecured loans).
- Fixed-rate deals can assist with budgeting.
Disadvantages:
- Larger deposits are needed compared to residential mortgages.
- Higher interest rates and fees.
- The application process is more complex and has stricter lending criteria.
- Risk of losing the property if the business struggles to meet repayments.
How to improve your chances of getting a commercial mortgage
If you’re considering applying for a commercial mortgage, here are a few practical tips to strengthen your application:
- Prepare detailed financial accounts – at least the past two to three years if possible.
- Create a solid business plan that explains how you’ll use the property and how it will generate income.
- Save a larger deposit to reduce the lender’s risk and potentially secure better terms.
- Check your personal and business credit reports for any errors and address them before applying.
- Work with an experienced commercial mortgage broker who knows which lenders are most likely to approve your application.
The bottom line
Although both residential and commercial mortgages involve borrowing money to purchase property, the similarities end there. Commercial mortgages are designed to meet business requirements, with different lending criteria, shorter terms, higher deposits, and fewer regulatory protections.
If you’re looking to buy, refinance, or invest in a property for business use, understanding these differences is crucial. With the right preparation and the right advice, a commercial mortgage can be a powerful tool to help your business grow and succeed.
