When applying for a commercial mortgage, understanding how deposits, interest rates and loan terms work is essential. These three elements have a major impact on how much you can borrow, what you will pay each month and the overall cost of purchasing business property.
Unlike residential mortgages, commercial lending is based more heavily on business performance and perceived risk. This means terms can vary significantly between lenders and across different industries.
Commercial mortgage deposits
One of the biggest differences in commercial property finance is the size of the deposit required. Most lenders typically ask for 20% to 40% deposit of the property value. In some cases, especially for higher-risk sectors or newer businesses, deposits may be higher.
For example, on a £750,000 property:
- 20% deposit is £150,000
- 30% deposit is £225,000
The deposit amount depends on several factors, including
- Business trading history
- Profitability and cash flow
- Credit history
- Property type and condition
- Industry risk level
Established businesses with strong financials are more likely to secure lower deposit requirements, while startups may need to contribute more equity or provide additional security.
Commercial mortgage interest rates
Commercial mortgage rates are generally higher and more variable than residential mortgage rates due to increased lending risk. Rates can be:
- Fixed – stable monthly payments for a set period
- Variable – can rise or fall with market conditions
- Tracker – linked to a base rate such as the Bank of England rate
Typical commercial mortgage rates vary widely depending on risk profile, but lenders will consider:
- Business financial strength
- Deposit size (higher deposits often mean lower rates)
- Loan-to-value ratio
- Property type and location
- Credit history
A stronger financial position usually results in more competitive rates, while higher-risk applications may attract higher interest.
Loan terms explained
Commercial mortgage terms refer to the length of time over which the loan is repaid. Most commercial mortgages are offered over 5 to 25 years. Shorter terms generally mean higher monthly repayments, but less total interest paid overtime. Longer terms reduce monthly costs but increase the overall interest paid.
Lenders also structure repayments in different ways:
- Capital repayment mortgages – You repay both the loan and interest monthly. At the end of the term, the property is fully owned.
- Interest-only mortgages – You only pay interest during the term, with the requirement to repay the full capital sum at the end of this period. This can improve cash flow but requires a clear exit strategy.
What lenders look for
Lenders assess risk carefully before approving a commercial mortgage. Key factors include:
- Business performance – Strong turnover, profit and cash flow improve approval chances.
- Trading history – Most lenders prefer at least 2 years of trading accounts.
- Credit profile – Both business and personal credit history are reviewed.
- Deposit size – A larger deposit reduces lender risk and can improve terms.
- Property type – Standard, easily lettable properties are often seen as lower risk.
- Affordability – Lenders will check whether the business can comfortably afford repayments.
Final thoughts
Commercial mortgage deposits, rates and terms all depend on the strength and stability of your business, as well as the type of property you are buying. While requirements can vary widely, understanding what lenders look for puts you in a stronger position when applying.
Preparation is key. The more stable your financial position and the larger your deposit, the more likely you are to secure favourable rates and flexible terms that support long-term business growth.
