At some point, most growing businesses hit the same wall: you’ve outgrown your space, or you’ve found a property that could take your business to the next level, and the bank account simply isn’t there to buy it outright. That’s the exact gap commercial finance exists to fill.
Whether you’re purchasing your first office, expanding into a warehouse, or investing in commercial property as part of a wider portfolio, understanding how a commercial mortgage actually works will save you time, money, and a fair few headaches. Here’s the plain-English version.
Commercial Mortgage vs Residential Mortgage Why They’re Not the Same Product
A residential mortgage is assessed largely on your personal income and the property’s value. A commercial mortgage is a different animal entirely lenders look at the business behind the purchase, the property’s use, projected income (if it’s an investment), and a wider set of risk factors that simply don’t apply to buying a house.
This is why commercial lending sits outside the mainstream high street mortgage market, and why working with a commercial mortgage broker who understands business finance specifically tends to produce far better outcomes than approaching a single bank directly.
How Do Commercial Mortgages Work?
At a basic level, a commercial mortgage is a loan secured against a non-residential (or mixed-use) property, repaid over an agreed term typically 3 to 25 years. Two broad categories cover most applications:
- Owner-occupier mortgages for businesses buying premises they’ll trade from themselves, like a shop, office, or workshop
- Commercial investment finance for buying property to let to other businesses, where the lender assesses projected rental income alongside the applicant’s financial position
Rates, terms, and Loan to Value (LTV) limits vary significantly depending on which category you fall into, the property type, and the strength of your business or investment case.
Who Can Apply for Commercial Finance?
More applicants qualify than most people assume. Commercial finance is available to:
- Established businesses purchasing trading premises
- Property investors building or expanding a commercial portfolio
- Startups though commercial finance for startups typically requires a stronger business plan and may involve higher rates or additional security, since there’s no trading history to assess
- Limited companies, partnerships, and sole traders
- Developers taking on conversion or refurbishment projects
Every lender weighs these applicants differently, which is exactly why comparing multiple lenders through a broker matters more in commercial lending than almost anywhere else in property finance.
What Deposit Is Required for a Commercial Mortgage?
Deposit requirements for commercial property tend to run higher than residential. As a general guide:
- Owner-occupier purchases typically 20–30% deposit
- Investment purchases often 25–40%, depending on projected rental yield and lender appetite
- Specialist or higher-risk sectors sometimes higher still
The exact figure depends heavily on the property type, your trading history (or lack of it), and how the lender views the sector you’re in. A commercial finance broker can usually give you a realistic figure early on, before you commit time to a specific property.
Commercial Finance by Property Type
Different property types come with different lending considerations:
- Commercial mortgage for offices generally the most straightforward category, particularly for owner-occupiers
- Commercial mortgage for retail units lenders will look closely at footfall, lease terms (if let), and location resilience
- Commercial finance for warehouses increasingly popular given demand from logistics and e-commerce businesses, though specialist valuation is often required
- Mixed-use and semi-commercial property combines residential and commercial elements, which narrows the pool of lenders willing to fund it, but bridging or specialist commercial products can often step in
When Speed Matters: Commercial Bridging Finance
Standard commercial mortgages can take weeks sometimes months to complete, which is a problem if you’re up against an auction deadline, a seller wanting a fast sale, or a business opportunity that won’t wait.
This is where commercial bridging finance earns its place. It’s short-term funding designed to help you purchase, refinance, or release capital from a commercial property while a longer-term solution like a standard commercial mortgage is arranged behind the scenes. It’s commonly used to:
- Complete an auction purchase within tight deadlines
- Secure business premises before a competitor does
- Refinance an existing commercial loan
- Release equity from a property you already own
- Support refurbishment or conversion projects before refinancing onto a standard mortgage
Because it’s short-term by design, lenders will always want to see a clear exit strategy — most commonly refinancing onto a commercial mortgage, selling the property, or repaying through business funds.
Refinancing: Don’t Just Set and Forget
Commercial property refinance is worth revisiting periodically, not just at renewal. Interest rates, your property’s value, and your business’s financial position all shift over time and a property refinanced today at better terms can free up working capital for stock, staffing, equipment, or further expansion.
Business Expansion: Beyond Property Alone
Property finance is often just one part of a growth plan. Alongside a commercial mortgage, businesses expanding into new premises sometimes also draw on:
- Asset finance spreading the cost of equipment, machinery, or vehicles
- Business loans for working capital or short-term cash flow needs
- Development finance for ground-up construction or major conversion projects
A broker working across the whole market can help you see how these pieces fit together, rather than approaching each one in isolation.
Why Use a Commercial Finance Broker
Commercial lending is genuinely more fragmented than residential different lenders specialise in different sectors, property types, and business profiles, and criteria can vary wildly between them. A broker who works across the whole market, rather than one bank’s own product range, typically identifies options a direct application would never surface.
Discount Mortgages can help you search the market for suitable commercial finance and commercial bridging options, reviewing your property type, loan amount, business use, and exit strategy to help match you with the right lender.
