A commercial mortgage deposit is the borrower’s financial contribution towards buying or refinancing a commercial property.
The deposit required is not set by one universal rule. It depends on the property, its use, the borrower, the business and the lender’s assessment of risk.
At a Glance
Commercial mortgage deposits commonly represent a larger percentage of the property value than residential mortgage deposits.
The required amount may be influenced by:
- The lender’s maximum loan-to-value
- Whether the property is owner-occupied or rented out
- The property type, condition and location
- Business accounts or rental income
- Trading history and sector risk
- The valuation and purchase price
- The borrower’s experience and credit position
- The proposed repayment strategy
A larger deposit reduces the percentage being borrowed. However, it does not remove the need to meet the lender’s wider criteria.
How Commercial Mortgage Deposits Work
The deposit normally forms the borrower’s equity in the property. It is not usually a separate sum retained by the mortgage lender.
For example, where a lender offers 70% loan-to-value, the borrower would normally need to provide the remaining 30%. Purchase costs and professional fees must usually be funded separately.
The commercial property normally provides the principal security for the mortgage.
This distinction matters. The lender is not only measuring how much money the borrower can contribute. It is assessing the strength of the property, income and repayment route supporting the loan.
What Is Loan-to-Value?
Loan-to-value, usually shortened to LTV, compares the mortgage amount with the lender’s accepted property value.
The calculation is:
Mortgage amount ÷ property value × 100 = LTV
A £600,000 mortgage against a property valued at £800,000 represents 75% LTV. The borrower’s equity contribution would be £200,000, excluding fees and taxes.
However, lenders normally use the lower of the purchase price or valuation when calculating their exposure. A lower-than-expected valuation can therefore increase the deposit required.
What Deposit Might a Commercial Mortgage Require?
Commercial mortgage deposit requirements often begin at around 20% to 40% of the property value. Some cases may fall outside this range.
The amount depends on the complete application rather than the deposit alone.
A lower deposit may be considered where the property is readily saleable and the borrower presents a strong financial case. A larger contribution may be required for specialist buildings, weaker trading results, limited experience or higher-risk sectors.
Advisers should avoid treating a published maximum LTV as a guaranteed lending level. The final offer may be lower after underwriting and valuation.
Owner-Occupied Commercial Property
An owner-occupied commercial mortgage may be used when a business buys premises from which it will trade.
The lender may assess:
- Historic business accounts
- Recent management figures
- Bank statements
- Tax information
- Trading history
- Existing business commitments
- Projected mortgage payments
- The proposed use of the building
- The experience of the directors or owners
The deposit is only one part of this assessment. A lender must also be satisfied that the business can support the mortgage payments.
Commercial Investment Property
A commercial investment mortgage may be used to buy a property that will be rented to another business.
Here, the lender may place greater weight on:
- Current and expected rental income
- Lease length
- Break clauses
- Tenant strength
- Rent review provisions
- Vacant periods
- Property location
- Investor experience
- Interest cover
- The proposed exit strategy
A strong deposit cannot always compensate for an unsuitable property or weak lease. The quality and reliability of the income remain important.
Why Property Type Affects the Deposit
Commercial properties are not assessed as one standard category.
An office, warehouse, shop, restaurant, care home and mixed-use building may each attract different lending criteria. Lenders consider how easily the property could be sold or reused if the borrowing fails.
A more specialised building may have a smaller resale market. That can result in a lower maximum LTV and a higher deposit requirement.
The most valuable deposit is therefore not always the largest. It is the deposit placed into a structure that matches the property, borrower and lender criteria.
Can Additional Security Reduce the Cash Deposit?
Some lenders may consider additional property security in suitable cases.
This could allow equity in another property to support the transaction. However, it places that additional asset at risk and may involve further valuations, legal work and lender conditions.
It should not be presented as a simple substitute for cash. The complete borrowing structure must remain affordable and suitable.
What Evidence Is Needed for the Deposit?
Lenders and legal professionals will normally need to verify where the deposit came from.
Evidence may include:
- Business or personal bank statements
- Savings records
- Property sale documents
- Evidence of retained business profits
- Investment statements
- Gift documentation
- Details of borrowing secured elsewhere
- Company accounts or dividend records
Unexplained transfers or late changes to the source of funds can delay underwriting and legal work.
Advisers should establish the source, ownership and availability of the deposit early in the process.
Why Case Presentation Matters
Commercial mortgage applications are often assessed individually. Clear case presentation helps the lender understand the transaction before detailed underwriting begins.
A strong submission should explain:
- What the client is buying or refinancing
- How the property will be used
- How much the client is contributing
- Where the deposit came from
- How repayments will be maintained
- Why the requested lender and structure are appropriate
- What the borrower intends to do at the end of the term

Commercial Mortgage Support for Network Advisers
Commercial cases can involve individual lender appetite, detailed valuations and several income sources. For advisers, access to experienced case support can improve early lender selection and reduce avoidable submissions.
A complete mortgage network can help advisers review property type, deposit, documentation and potential lender criteria before an application is made.
The objective is not simply to find the highest published LTV. It is to identify a structure that the lender can understand, assess and support.

Frequently Asked Questions
What is the minimum deposit for a commercial mortgage?
There is no universal minimum. Requirements depend on the lender, property, borrower and purpose of the mortgage. Deposits commonly fall within the 20% to 40% range, although individual cases can require more or less.
Does a larger deposit guarantee a lower commercial mortgage rate?
No. A larger deposit may reduce the lender’s loan-to-value and overall exposure. However, pricing can also depend on the property, sector, income, lease, trading performance, borrower experience and loan structure.
Are commercial mortgage fees included in the deposit?
Usually not. Valuation fees, legal fees, lender charges, broker fees and applicable taxes may need to be funded separately. These costs should be included in the client’s cash requirement from the outset.
Can a commercial mortgage deposit be borrowed?
Some lenders may consider borrowed funds or additional secured borrowing. Others may restrict them. The lender will assess the source, repayment cost and effect on the borrower’s overall financial position.
Why might the required deposit increase after valuation?
The lender may calculate LTV using the lower of the purchase price or valuation. If the valuation is below the agreed price, the maximum mortgage may fall, increasing the borrower’s required contribution.
Some commercial mortgages and business finance arrangements are not regulated by the Financial Conduct Authority. The regulatory position depends on the borrower, property and purpose of the borrowing. Property used as security may be repossessed if repayments are not maintained.
