Commercial mortgage deposits are not set by one simple rule. The right amount depends on the property, loan-to-value, business income or rent, borrower strength, credit profile and how the deal is structured. This guide explains what to prepare before you apply.
How much deposit do you need for a commercial mortgage?
Many commercial mortgage enquiries need a larger deposit than a typical residential mortgage, but there is no fixed percentage that applies to every borrower. Some cases may be considered with a lower contribution when the property, accounts, rent and borrower profile are strong. Other cases need more equity because the property is specialist, the income is harder to prove, the lease is weak, the sector is higher risk or there is adverse credit.
- For owner-occupied premises, lenders usually focus on the trading business, accounts, affordability and management experience.
- For commercial investment property, lenders usually focus on rental income, lease quality, tenant strength and resale risk.
- For refinancing, the question is often whether existing equity is enough after valuation, fees, repayment costs and any capital being raised.
What lenders count as deposit or equity
A deposit is the money or equity you contribute so the lender is not funding the full property value. In a purchase, it is usually cash paid towards the price. In a remortgage or refinance, it may be the equity already held in the property. In some cases, equity in another property can form part of the wider structure, but the lender will still want to understand valuation, security, repayment route and source of funds.
If you hope to proceed without a cash deposit, read how a 100% commercial mortgage normally depends on acceptable additional security rather than the purchase property alone.
Money from the borrower, company, directors, retained profits, sale proceeds or other acceptable sources, supported by clear evidence.
Value already built up in an existing property, subject to valuation, current borrowing, lender appetite and security position.
Funds introduced by directors or shareholders may be possible, but lenders will normally ask where the money came from and whether it is repayable.
Some borrowers use a refinance to raise capital, but the final amount depends on valuation, affordability and the lender’s maximum loan-to-value.
What can increase or reduce the deposit needed?
Lenders do not look at the deposit in isolation. They look at whether the whole case makes sense. A strong deposit can help, but it does not fix every issue if the property is difficult to value, income is unclear or the repayment route is weak.
Standard trading premises can be easier to assess than highly specialist, short-lease or unusual properties.
Accounts, rent, lease terms, tenant quality and bank statements help lenders judge whether repayments are sustainable.
Lenders may take more comfort from experienced operators, established landlords and businesses with clear management records.
Adverse credit does not always stop a case, but it can reduce lender choice and may increase the equity expected.
Buying premises, refinancing, raising capital or funding refurbishment can each be assessed differently.
Clean documents, a realistic valuation and a clear explanation can make the enquiry easier to place with suitable lenders.
Typical deposit scenarios to discuss with a broker
These examples are not promises of approval. They show why two borrowers asking for a commercial mortgage can receive very different lender feedback, even when the purchase price looks similar.
The lender will usually want to understand trading history, accounts, current rent or occupancy costs, deposit source and whether the new premises support the business.
Rental income, lease length, tenant strength, location and property saleability are central because the rent often supports the borrowing.
Lenders may consider company borrowing, but they will review the company structure, directors, accounts, deposit source and sometimes personal guarantees.
The available equity depends on current value, existing borrowing, repayment record, purpose of funds and whether the lender is comfortable with the final loan-to-value.
Useful rule of thumb: before spending money on valuations or legal work, ask for an initial lender-fit review. It is better to find out early if the deposit is likely to be strong enough or if the case needs more preparation.
Acceptable deposit sources need clear evidence
Commercial mortgage lenders and solicitors will usually want to understand where the deposit came from. The cleaner the evidence, the easier it is to assess the case. If the deposit is coming from more than one place, explain that early rather than waiting until underwriting.
Often evidenced through accounts, management figures and bank statements.
Lenders may ask for statements and an explanation of whether funds are being gifted, loaned or invested.
Usually easier to evidence when supported by completion statements and bank records.
Can be viable, but the order of transactions, valuation and security position matter.
When a smaller deposit may not be the best answer
A lower deposit can look attractive because it keeps more cash in the business. It can also create risk if repayments become stretched, refurbishment costs are underestimated or the lender prices the loan higher because the case is more leveraged.
The right question is not only “what is the smallest deposit possible?” It is also “what structure gives me a realistic chance of approval and leaves enough working capital after completion?”
How to prepare a stronger deposit enquiry
You do not need a perfect application before asking for guidance, but a few details make the first review much more useful. Count Ready can then explain whether the deposit position looks realistic, what evidence is missing and which lender routes may be worth considering.
- Property address or type, purchase price or estimated value.
- How much cash deposit or equity is available.
- Whether the property will be used by your business, let to tenants or held as an investment.
- Recent accounts, rental details or a brief explanation of the income supporting the loan.
- Any credit issues, missed payments, arrears or previous lender declines.
- Your target timescale and any offer, auction or refinance deadline.

Questions people ask before applying
There is no single fixed deposit for every commercial mortgage. The amount depends on the property, borrower, income, credit profile, loan-to-value, lender appetite and whether the case is owner-occupied, investment or refinance.
It may be possible in some strong cases, but it is not guaranteed. Lenders will look at the quality of the property, income evidence, borrower strength and overall risk. Some enquiries will need a larger contribution.
Sometimes equity can help structure a case, especially on refinance or additional security discussions. The lender will still need to assess valuation, existing borrowing, security, affordability and the purpose of funds.
Possible sources include business funds, retained profits, personal savings, director or shareholder funds, sale proceeds and refinance proceeds. The important point is that the source must be clear and properly evidenced.
Adverse credit can reduce lender choice and may mean the lender wants more equity, but the outcome depends on the type, age and seriousness of the issue as well as the strength of the property and income.
Prepare the property details, price or value, deposit or equity available, purpose of the loan, income evidence, credit background and timescale. This helps a broker give more useful lender-fit feedback.
