Commercial Mortgage Deposit Guide: How Much You Need and What Drives the LTV

Commercial mortgage deposits: what to expect

When you apply for a commercial mortgage, the deposit you can put down is one of the key factors lenders use to judge risk. Commercial lending can be more flexible than many residential mortgages, but lenders still expect you to have a meaningful stake in the property and/or the deal.

Typical commercial mortgage deposit range

In many cases, a commercial mortgage deposit is often around 20% to 40%.

That said, the “right” deposit for your situation can be higher or lower depending on how the lender views the overall risk of the transaction.

What affects how much deposit you need?

Commercial lenders look at several areas when deciding the deposit they want. While each lender has its own approach, common considerations include:

1) Your business and trading track record

A business with a proven history of trading and credible plans is often viewed as lower risk than a new venture or a business with limited evidence of performance. Lenders may therefore be more comfortable with a lower deposit where the income and management track record are strong.

2) Profitability and affordability signals

Lenders typically want confidence that the business can meet the mortgage payments. Strong profitability and realistic forecasts can support a more competitive loan-to-value (LTV), while weaker trading performance or uncertain income may push the lender towards a higher deposit.

3) The type of commercial property

Some property categories are considered more straightforward to value and manage than others. For example, a well-let office building for an established business may be assessed differently from higher-risk sectors.

4) Whether it’s owner-occupied or investment

How the property will be used can influence risk. In general terms:

• Owner-occupied situations may be viewed as less complex than investment lending.
• Investment lending can be assessed more like buy-to-let, where the lender may focus on the strength of rental income and tenant-related risk.

5) Credit history (for you and/or the business)

If there are adverse credit markers, lenders may reduce the amount they are willing to lend, which can translate into a higher deposit requirement. In some cases, specialist lenders may be more relevant.

6) Property condition and construction type

Properties that require major refurbishment, have non-standard construction, or carry additional technical risks can lead to a higher deposit expectation. This is often because the lender may need more protection if the property’s value or future saleability is uncertain.

7) Loan structure and lender minimums

Even where the LTV might suggest a lower deposit could be possible, some lenders apply minimum deposit levels for certain commercial products or circumstances.

Low-deposit options: what’s possible?

It can be possible to secure a commercial mortgage with a lower cash deposit, but it often becomes more complex. Lenders may look for additional security or stronger compensating factors.

Using other assets as security

Where you don’t have a large cash deposit, some deals may be structured using other assets as additional security. This could include:

• assets owned by the business
• assets owned personally by the borrower

If another property is involved, the lender may require a specific legal arrangement to protect their position.

Combining cash and other forms of security

A common approach is to combine a smaller cash deposit with additional security. This can help broaden lender choice, although it may still result in tighter terms compared with deals where a larger deposit is available.

Funding your deposit: practical ways borrowers approach it

The most straightforward deposit is cash. In practice, many borrowers explore other ways to assemble the deposit, such as:

• Working capital
• External investment
• Bridging finance (where a sale is planned)
• Commercial finance
• A combination of the above

In some circumstances, other sources may be considered, but lenders will typically want to understand the nature of the funds and how they fit into the overall deal.

Source of deposit checks

Lenders may request evidence of where the deposit money comes from. This is to ensure the funds are legitimate and consistent with the transaction.

How a broker can help with deposit planning

Commercial mortgage deposit requirements can vary significantly by lender and by the details of the property and business. A broker’s role is to help you understand how different lenders may view your risk profile and to position your application accordingly.

A broker can also help you:

• identify lenders whose criteria may align with your deposit level
• present the information lenders need to assess risk
• consider whether a different structure (for example, owner-occupied vs investment approach, or additional security) could support a more suitable deposit

Key takeaway

A commercial mortgage deposit is often in the 20% to 40% range, but the exact figure depends on factors such as your business profile, the property type, how the property will be used, credit history, and the lender’s appetite for risk.

If you’re working with limited cash, there may be options to structure the deal differently—often involving additional security or a mix of funding sources—while still meeting the lender’s requirements.
