Commercial Mortgage Deposit Guide: How Much Do You Need?

The deposit is the biggest upfront cost when purchasing commercial property and often the biggest barrier to entry. Unlike residential mortgages where 90-95% loan-to-value products exist, commercial mortgages typically require 25-40% of the purchase price as a deposit. Getting the deposit right is fundamental to a successful application.

As an ex-banker who has assessed hundreds of commercial mortgage applications, I can tell you that deposit is about far more than just having the money. Where it comes from, how you structure it, and how it relates to the overall deal all matter. This guide covers everything you need to know about commercial mortgage deposits.

Minimum Deposit by Property Type

Deposit requirements vary significantly by property type because lenders assess risk differently across sectors. Properties that are easier to sell, have more stable values, and generate more reliable income require smaller deposits.

Standard Commercial Property

Property Type Maximum LTV Minimum Deposit
Industrial / warehouse 75% 25%
Office (prime location) 75% 25%
Office (secondary) 70% 30%
Retail (prime high street) 70% 30%
Retail (secondary location) 60-65% 35-40%
Mixed-use (shop with flat) 75% 25%
Multi-let commercial 70% 30%

Specialist Property

Property Type Maximum LTV Minimum Deposit
Pub / bar 60-70% 30-40%
Hotel / guest house 55-65% 35-45%
Restaurant / takeaway 60-65% 35-40%
Care home 65-70% 30-35%
Holiday let 65-75% 25-35%
Petrol station 60-65% 35-40%
Land (with planning) 60-65% 35-40%
Land (without planning) 40-50% 50-60%

These are typical maximum LTV figures. Your actual deposit requirement may be higher depending on your financial profile, the specific property, and the lender's assessment.

Why Commercial Deposits Are Higher Than Residential

Several fundamental differences between commercial and residential property explain the higher deposit requirement.

Liquidity Risk

Commercial property takes significantly longer to sell than residential. If a lender needs to repossess and sell a commercial property, the process can take 12-24 months or more. A larger deposit provides a bigger buffer against losses during this period and against potential value declines.

Valuation Volatility

Commercial property values are driven by income, and income can change. A tenant vacating, a rent reduction, or a change in market conditions can materially affect value. The deposit buffer protects the lender against these income-driven valuation changes.

Specialist Nature

Many commercial properties are purpose-built for specific uses. A factory configured for a particular manufacturing process, a restaurant fitted out for a specific operator, or a care home built to CQC standards all have limited alternative use value. The deposit accounts for this reduced marketability.

Regulatory Framework

Residential mortgages are heavily regulated by the FCA with standardised criteria and consumer protections. Commercial lending operates under a less prescriptive framework, leading lenders to manage risk through equity requirements rather than regulatory constraints.

Acceptable Sources of Deposit

Lenders scrutinise deposit sources as part of anti-money laundering (AML) compliance and to assess the quality of the borrower's financial position.

Cash Savings

The most straightforward source. You need to provide bank statements showing the funds have been held or accumulated over time. Large unexplained deposits in your bank statements will be queried.

Business Reserves

Accumulated profits within your business can be used as deposit. Lenders will assess whether withdrawing these funds compromises the business's working capital position. A business that strips all its cash for a property deposit raises concerns about future operational funding.

Equity Release from Existing Property

Remortgaging an existing property to release equity is one of the most common deposit sources for commercial investors. This works particularly well when you own residential or commercial property with significant equity growth.

Key considerations:

  • The remortgage must be in place before or simultaneously with the commercial purchase
  • Lenders will factor the additional borrowing into your overall affordability assessment
  • Cross-charging (using existing property as additional security) may be an alternative to equity release

Sale Proceeds

Proceeds from selling property, investments, or business assets are acceptable with evidence of the original ownership and the sale transaction.

Gifted Deposit

Some commercial lenders accept gifted deposits, though this is less common than in residential lending. The donor must confirm the gift is non-repayable and provide evidence of their own funds. Not all lenders accept gifts for commercial mortgages.

Director's Loan

Directors can lend money to their company for the deposit. Lenders will examine the loan terms and whether repaying the director creates a cash flow burden on the business.

Pension Funds (SIPP/SSAS)

Self-Invested Personal Pensions (SIPPs) and Small Self-Administered Schemes (SSASs) can invest directly in commercial property. The pension fund provides the deposit, and a commercial mortgage within the pension funds the balance. This is one of the most tax-efficient routes to commercial property ownership.

A SIPP or SSAS can borrow up to 50% of the net fund value, meaning a pension fund with £200,000 could access up to £100,000 of borrowing, giving a total purchasing power of £300,000.

Vendor Finance

In some transactions, the seller defers part of the purchase price, effectively providing vendor finance. Not all lenders accept this, and those that do typically require the vendor finance to be subordinate to the commercial mortgage and unsecured against the property.

Strategies to Reduce Your Deposit

If the standard deposit requirement is a barrier, several approaches can help.

Offer Additional Security

If you own other property, offering it as additional security allows some lenders to increase LTV on the target purchase. A property worth £300,000 with an existing mortgage of £150,000 provides £150,000 of additional security that could reduce or eliminate your cash deposit requirement.

Negotiate the Purchase Price

The most direct route to a smaller deposit. A 10% reduction in purchase price reduces your absolute deposit by the same proportion. In many commercial transactions, there is more room for negotiation than you might expect, particularly for properties that have been on the market for some time.

Use Mezzanine Finance

Mezzanine finance sits between the senior commercial mortgage and your equity. A senior lender provides 60% LTV, a mezzanine lender provides an additional 15-20%, and your deposit covers the remaining 20-25%. Mezzanine is more expensive than senior debt (typically 10-15% per annum) but cheaper than equity for many investors.

Joint Venture

Partnering with another investor pools capital. Many successful commercial property portfolios started as joint ventures where two or more parties combined deposit resources. The partnership agreement should clearly define ownership, profit sharing, decision-making, and exit provisions.

Bridging as a Stepping Stone

If you have equity that will become available shortly (from a property sale completing, a refinance in progress, or a business disposal), bridging finance can fund the purchase now. Once the equity arrives, you repay the bridging loan and refinance to a long-term commercial mortgage.

Start Smaller

A smaller property requires a proportionally smaller deposit. Building experience and equity through smaller initial purchases creates a track record and capital base for larger acquisitions later.

Total Upfront Costs: Beyond the Deposit

The deposit is the largest component of your upfront costs, but it is not the only one. Budget for the full picture.

Cost Breakdown for a Typical Purchase

For a £600,000 commercial property at 70% LTV:

Cost Amount
Deposit (30%) £180,000
Stamp Duty Land Tax £19,500
Arrangement fee (1.5% of £420,000 loan) £6,300
Lender's valuation £2,500-£4,000
Your solicitor's fees £4,000-£8,000
Lender's solicitor's fees £2,500-£5,000
Searches and disbursements £1,000-£2,000
Survey (if separate from valuation) £1,500-£3,000
Total upfront costs £217,300-£227,800

The total upfront cost is typically 20-30% higher than the deposit alone. Failing to budget for these additional costs can derail a purchase after significant time and effort has been invested.

Deposit for Refinancing

When refinancing an existing commercial property, the concept is equity rather than deposit. The same LTV limits apply, but the assessment is against the current market value of the property.

If your property has increased in value since purchase, you may have more equity than you realise. A property purchased for £400,000 three years ago might now be worth £500,000, giving you £100,000 of additional equity that could be released through refinancing.

Conversely, a property that has declined in value may present a refinancing challenge if equity is insufficient for the required LTV.

What If You Do Not Have Enough?

If your available deposit falls short:

  1. Reassess your target: Could a lower-value property achieve your objectives?
  2. Explore alternative structures: SIPP purchase, joint venture, or additional security
  3. Consider timing: Wait until additional savings or equity release is available
  4. Investigate specialist lenders: A small number of lenders offer higher LTV for strong cases
  5. Speak to a broker: An experienced broker may identify solutions you have not considered

Do not stretch beyond what you can comfortably afford. Maintaining adequate reserves after the purchase is essential for managing unexpected costs and ensuring the business or investment has working capital.

Planning Your Deposit: Practical Steps

  1. Calculate your total budget: Include all purchase costs, not just the deposit
  2. Document your sources: Start gathering evidence of where funds have come from
  3. Verify availability: Ensure funds are accessible and not locked in illiquid investments
  4. Consider tax implications: Releasing equity or withdrawing from investments may trigger tax liabilities
  5. Maintain reserves: Budget to retain 3-6 months of operating costs after the purchase
  6. Get broker advice early: A broker can tell you what deposit level unlocks the best terms for your specific property type

Frequently Asked Questions

What is the minimum deposit for a commercial mortgage?

The minimum deposit for a standard commercial mortgage is typically 25% (75% LTV) for mainstream property types like offices, industrial units, and mixed-use buildings. Specialist properties such as pubs, hotels, and care homes typically require 30-45% deposit. The exact requirement depends on the property type, your financial profile, and the lender's appetite for the specific deal.

Can I get a 100% commercial mortgage with no deposit?

True 100% commercial mortgages are extremely rare, but it is possible to purchase commercial property with no cash deposit by offering additional security from other property you own. If you have sufficient equity in existing assets, a lender may accept this as security in lieu of a cash deposit, effectively achieving 100% funding of the purchase price.

Can I use my pension to fund a commercial property deposit?

Yes, Self-Invested Personal Pensions (SIPPs) and Small Self-Administered Schemes (SSASs) can purchase commercial property directly. The pension fund provides the equity, and a commercial mortgage within the pension funds the balance. The pension can borrow up to 50% of its net value. This is one of the most tax-efficient routes to commercial property ownership.

Do I need to prove where my deposit came from?

Yes, anti-money laundering regulations require lenders to verify the source of your deposit. You will need to provide evidence such as bank statements showing savings accumulation, completion statements from property sales, business accounts showing retained profits, or documentation of gifts. Large unexplained cash deposits will be questioned.

Can I use a gifted deposit for a commercial mortgage?

Some commercial lenders accept gifted deposits, though it is less common than in residential mortgage lending. The donor must confirm the gift is non-repayable and provide proof of their own funds. Not all lenders accept gifts, so it is important to check policy before relying on this as your deposit source.

How much extra do I need beyond the deposit for purchase costs?

Budget for total upfront costs of 20-30% more than the deposit alone. Additional costs include Stamp Duty Land Tax, arrangement fees (1-2% of the loan), valuation fees, solicitor fees for both sides, searches, and a building survey. For a £500,000 purchase, total costs beyond the deposit are typically £25,000-£40,000.
