For many business owners, the transition from tenant to owner is a defining moment that secures the company’s future and builds long-term wealth. While commercial mortgages work differently to residential mortgages and may seem complex at first sight, the differences can be viewed as a major advantage. Instead of being restricted by a simple salary multiplier, commercial lenders look at the bigger picture – the strength of your business, the value of the property, and your vision for the future.
This bespoke approach means there is often more room for a ‘yes’ if you have a solid plan. Whether you are looking to purchase your first warehouse, move your retail shop to a prime high-street location, or invest in a multi-unit office block, understanding how lenders view your business is the first step toward unlocking the capital you need. In this guide, we’ll break down the mechanics of commercial lending, explain how lenders will determine your borrowing power, and give you the knowledge you need to take that next big step.
What are the Pros and Cons of a Commercial Mortgage?
Before diving into the ‘how much,’ it’s vital to understand the trade-offs of entering into a long-term commercial debt commitment.
The Pros of a Commercial Mortgage
- Capital Growth – You benefit from any increase in the property’s value over time.
- Fixed Cost Certainty – You’ll protect your business from the ‘upward-only’ rent reviews common in leases.
- Building Equity – Your monthly payments contribute to an asset on your balance sheet, building your wealth not your landlord’s.
- Interest Tax Deductions – Mortgage interest is generally a tax-deductible business expense.
The Cons of a Commercial Mortgage
- Significant Deposit – Expect to provide 25% to 40% of the purchase price upfront.
- Maintenance Liability – You are responsible for all structural repairs and insurance.
- Market Risk – If the value of the property were to drop, your equity could be affected.
- Reduced Liquidity – Some of your capital will be tied up in bricks and mortar rather than being available for ‘ready cash.’
What Type of Commercial Mortgage Do I Need?
The amount you can borrow often depends on who will be occupying the building – your company or a tenant. Lenders categorise these two use cases into two distinct products:
- Owner-Occupied Mortgages – These are for the business owner who want to buy a premises to run their own company from. For affordability, the lender will focus heavily on your trading accounts and your ability to ‘service the debt’ from your business profits.
- Commercial Investment Mortgages – These are for individuals or companies looking to buy a property and let it out to a third-party tenant. For affordability, the lender will be less interested in your personal income and more interested in the rental yield the property will generate.
How is a Commercial Mortgage Loan-to-Value (LTV) Calculated?
The first ‘ceiling’ on your borrowing is the Loan-to-Value (LTV) ratio. While you might be used to seeing 90% or 95% mortgages in the residential world, commercial lenders are more conservative because the risk is generally higher. Most lenders cap their lending at 65% to 75% of the property’s value, meaning you’ll typically need a deposit of at least 25% to 35%.
For certain ‘strong’ sectors – such as medical practices, dental surgeries, or veterinary clinics – some specialist lenders may stretch to 80% or even 90% because these businesses are seen as incredibly stable. Conversely, for ‘risky’ properties like pubs or petrol stations, the LTV might drop to 50% or 60%.
Case Study: A Realistic Example of Commercial Borrowing
To see how this works in practice, let’s look at a common scenario for a growing business in the South East.
The Project: A light industrial engineering firm in Hampshire is currently paying £3,500 per month in rent. They want to buy a freehold warehouse valued at £500,000.
- The Deposit: The lender offers a 70% LTV mortgage. The business needs to provide a £150,000 deposit (plus VAT and fees).
- The Affordability: The lender looks at the company’s EBITDA (net profit + interest + depreciation). The annual mortgage payments on the £350,000 loan are approximately £28,000.
- The Result: Because the business shows a steady annual profit of £45,000, they meet the ‘Debt Service Cover’ requirements (1.6x coverage). The lender approves the loan, and the business effectively swaps a £42,000 annual rent ‘sunk cost’ for a £28,000 mortgage payment – saving £14,000 a year while building equity in a half-million-pound asset.

How Do Lenders Decide How Much I Can Afford?
Once the LTV is established, the lender needs to know you can actually afford the monthly repayments. They don’t just look at your turnover; they look at your EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortisation).
Lenders typically use a Debt Service Coverage Ratio (DSCR). Most want to see that your business’s adjusted net profit is at least 1.25 to 1.5 times the annual mortgage repayments.
For example, if you have a consistent net profit of £100,000, a lender using a standard 1.25x ‘buffer’ would typically be comfortable with you spending up to £80,000 a year on mortgage repayments. Based on current market rates over a 20-year term, this could translate to a borrowing potential of approximately £860,000, assuming you meet the property’s deposit requirements.
How Can I Increase My Commercial Borrowing Limit?
If your ‘maths’ isn’t quite reaching the purchase price you need, there are several levers we can pull to increase your borrowing potential:
- Additional Security – If you have equity in another commercial property or your own home, you can sometimes ‘cross-collateralise’ that equity to reduce the cash deposit required.
- SIPP or SSAS Pensions – As discussed in our previous guides, using your pension to purchase your premises can bridge the gap if your trading business is short on liquid cash for a deposit.
- Personal Guarantees – Providing a personal guarantee (PG) can sometimes give a lender the extra confidence needed to approve a slightly higher loan amount or a better interest rate.
- Experience – A ‘clean’ track record of running a profitable business for 3+ years will almost always unlock higher borrowing limits than a startup would receive.
How Do I Apply for a Commercial Mortgage?
Unlike regular residential mortgages, commercial mortgages are typically bespoke. Instead of ‘off-the-shelf’ products, every deal is negotiated based on the strength of your business plan and the quality of the property.
To get the maximum amount possible, you will need to present a professional ‘lending pack,’ which typically includes:
- Three years of certified accounts.
- Current business bank statements (usually the last 6 months).
- A detailed asset and liability statement for all directors.
- A professional valuation of the property (which the lender will instruct).

The Bottom Line
How much you can borrow on a commercial mortgage isn’t a fixed figure – it’s a reflection of your business’s health and the lender’s appetite for risk. While the ‘standard’ sits at around a 70% LTV with a 1.25x affordability cover, the reality is far more flexible when you have access to the whole of the market through a broker like us.
Moving from tenant to owner is a pivotal choice that balances immediate flexibility against long-term financial security. By stepping into the role of owner, you unlock tax efficiencies, capital growth, wealth generation, and the peace of mind that comes with owning the roof over your head.
