How Much Down Payment Do I Need to Buy a Commercial Building?

How Much Down Payment Do I Need to Buy a Commercial Building?

The down payment is usually the first question business owners ask when they consider buying commercial property. And for good reason. On a 1 million building, the difference between 10% down and 25% down is the difference between writing a check for 100,000 versus 250,000. That gap can determine whether a deal is feasible or dead on arrival.

The good news is that if your business will occupy the building, you have access to financing programs with significantly lower down payment requirements than pure investment property loans. Here is a clear breakdown of what to expect.

Down Payment Requirements by Loan Type

SBA 7(a): As Low as 0% SBA-Mandated Down for Existing Businesses

The SBA 7(a) program offers the lowest down payment requirements for owner-occupied commercial real estate, but the exact requirement depends on your situation. The SBA's Standard Operating Procedures (SOP 50 10 8) do not impose a one-size-fits-all minimum. Instead, the requirement varies based on the type of transaction:

• Existing businesses (operating more than one year, no change of ownership): The SBA does not mandate a specific minimum equity injection. The lender evaluates whether the borrower's overall equity position is adequate based on the deal's risk profile. Many lenders still request 10% or more, but there is no SBA-imposed floor.
• Startups (in operation one year or less): 10% of total project cost is required by the SBA.
• Changes of ownership (acquiring an existing business): 10% of total project cost is required by the SBA.
• Partner buyouts: No fixed percentage. The SBA uses a debt-to-worth test (9:1 ratio) rather than a specific equity injection percentage.

Total project cost is not just the purchase price. It includes the acquisition price of the property, any renovation or build-out costs being financed, closing costs rolled into the loan, and equipment if bundled into the same loan. So on a property with a 900,000 purchase price and 100,000 in renovations, the total project cost is 1 million.

When it might be higher: Even when the SBA does not mandate a minimum, individual lenders may request 10% to 20% or more based on the deal's cash flow coverage, property type, borrower credit profile, or industry experience. The SBA sets the floor; lenders set their own requirements above it.

SBA 504: 10% to 20% Down

The SBA 504 program also starts at 10% but has defined situations where more is required:

• Standard purchase: 10%
• Startup business (less than 2 years operating): 15%
• Special-use property (car wash, gas station, hotel): 15%
• Startup business AND special-use property: 20%

Because the 504 program splits the financing between a bank (50%) and a CDC (40%), your 10% is truly the smallest slice of the capital stack.

Conventional Commercial Loans: 15% to 25% Down

If you go with a traditional bank loan without SBA backing, expect to put down 15% to 25% for owner-occupied properties. The exact number depends on the bank's portfolio guidelines, property type and condition, your financial strength and borrowing history, and market conditions.

Some community banks will go as low as 15% for strong borrowers with long operating histories buying general-purpose buildings. Larger or riskier deals typically land at 20% to 25%.

Investment Property Loans: 25% to 30% Down

For comparison, if you are buying a commercial property purely as an investment (you will not occupy it), expect a minimum of 25% down and sometimes 30% or more. This is one of the key advantages of owner occupancy. Your down payment drops dramatically when your business is the primary tenant.

What Counts as a Down Payment (Equity Injection)

In SBA lending, the down payment is formally called an "equity injection." The SBA is specific about what qualifies.

Cash from Business or Personal Accounts

The most straightforward source. You write a check from your business operating account or personal savings. Lenders will want to see that these funds have been in your account for at least 60 to 90 days (sometimes called "seasoning") to confirm the money is genuinely yours and not a last-minute loan.

Gift Funds

Cash gifts from family members can count toward your equity injection. The SBA requires a gift letter confirming the funds are a true gift with no repayment obligation, documentation showing the donor has the financial capacity to make the gift, and a paper trail showing the transfer of funds.

Gifts from friends, business associates, or anyone with a financial interest in the transaction generally do not qualify.

Business Assets and Equity

If your business has equipment, inventory, or other assets being contributed to the project, their value can sometimes count toward equity injection. This is more common in business acquisition deals where the existing assets of the business being purchased contribute to the overall equity position.

Real Estate Equity

If you already own the property free and clear (or have significant equity in it) and are refinancing, the existing equity can satisfy the injection requirement. Similarly, if you own land and are constructing a new building, the value of the land can count.

Retirement Account Rollovers (ROBS)

Some borrowers use a Rollover for Business Startups (ROBS) structure to access retirement funds without early withdrawal penalties. The retirement funds are used to capitalize a C-corporation, which then invests in the business. This is a legitimate but complex strategy that requires specialized legal and tax guidance.

What Does NOT Count as a Down Payment

Understanding what the SBA will not accept is just as important.

Borrowed Funds (With One Key Exception)

Generally, you cannot borrow money and use it as your down payment. If you take out a personal loan, home equity line of credit, or credit card advance to fund your injection, the SBA will disqualify it. The logic is simple: your down payment is supposed to demonstrate that you have real financial commitment to the project, not that you can borrow from one place to pay another.

The exception: Seller standby notes, which we cover in detail below.

Sweat Equity

The SBA does not count your time, effort, or expertise as equity injection. Even if you plan to do 50,000 worth of renovation work yourself, that labor does not reduce your cash requirement.

Funds You Cannot Document

If you cannot show where the money came from with bank statements, tax returns, or other paper trails, it will not count. Lenders and the SBA require full sourcing documentation.

Seller Standby Notes: Reducing Your Cash Out of Pocket

A seller standby note is one of the most useful tools for business owners who want to reduce their cash requirement at closing. Here is how it works.

The Concept

The seller agrees to finance a portion of the purchase price as a loan to you. This note is subordinate to the SBA loan (meaning the SBA lender gets paid first) and must be on "full standby" for a defined period.

SBA Standby Requirements

For the SBA to approve a seller standby note as part of your equity injection:

• No payments for the full term of the SBA loan (principal and interest are deferred for the entire life of the SBA loan, not just a fixed period)
• The note must be subordinate to the SBA-guaranteed loan at all times
• Interest rate must be reasonable (typically at or below the SBA loan rate)
• Standby seller debt cannot exceed half of the required equity injection. For example, if your required equity injection is 100,000, no more than 50,000 can come from a standby seller note. The remaining 50,000 must come from other acceptable sources such as cash.

How It Reduces Your Cash Need

Example: You are buying a 1 million building with an SBA 7(a) loan.

Without a seller standby note:

• SBA loan: 900,000 (90%)
• Your cash down payment: 100,000 (10%)

With a seller standby note:

• SBA loan: 900,000 (90%)
• Seller standby note: 50,000 (5%)
• Your cash down payment: 50,000 (5%)

The seller is essentially financing part of your equity injection. You still have a 10% total injection (5% cash plus 5% seller note), but your out-of-pocket cash drops by half.

Why Would a Seller Agree to This?

Sellers accept standby notes for several reasons. It can help close a deal that otherwise might fall apart due to the buyer's cash constraints. The seller earns interest on the note. And in some cases, it helps the seller spread their capital gains tax liability over multiple years through installment sale treatment.

Not every seller will agree, but it is always worth asking, especially in deals where the property has been on the market for a while.

Practical Examples by Purchase Price

Here is what your down payment looks like at different price points and loan types.

500,000 Building

1 Million Building

2 Million Building

*The 10% figure shown for SBA 7(a) applies to startups and business acquisitions (changes of ownership). Existing businesses with more than one year of operating history have no SBA-mandated minimum -- the lender determines the adequate equity position, which may be less than 10%.

The savings from SBA financing are significant. On a 2 million building, the difference between 10% and 25% down is 300,000 in cash that stays in your business for operations, growth, or reserves.

Do Not Forget: Closing Costs and Reserves

Your down payment is not the only cash you need at closing. Budget for these additional items.

Closing Costs

Typical closing costs on a commercial real estate transaction run 2% to 5% of the loan amount and can include SBA guarantee fees, appraisal and environmental assessment fees, title insurance and recording fees, attorney and legal fees, and lender origination or processing fees.

Some of these costs can be financed into the loan (rolled in), but not all of them. Ask your lender early which costs must be paid out of pocket.

Post-Closing Reserves

Many lenders require that you maintain cash reserves after closing, typically three to six months of mortgage payments. If your monthly payment will be 8,000, expect to need 24,000 to 48,000 in reserves that you cannot use for your down payment.

Tips to Prepare Your Down Payment

1. Start saving early. The sooner you begin setting aside cash, the stronger your position when you find the right property.
2. Season your funds. Keep your down payment money in your account for at least 60 to 90 days before applying. Lenders will question large recent deposits.
3. Explore seller standby notes. Negotiate with the seller to reduce your cash requirement at the deal table.
4. Consider gift funds carefully. If a family member can help, get the gift documentation right from the start.
5. Budget beyond the down payment. Factor in closing costs and reserves so you are not caught short at the finish line.
6. Keep detailed records. Every source of funds needs a paper trail. Bank statements, tax returns, and transfer confirmations are essential.

Key Takeaways

• SBA loans offer the lowest down payments for owner-occupied commercial property. The 7(a) program requires 10% for startups and acquisitions but has no SBA-mandated minimum for existing businesses, while the 504 starts at 10%. Both compare favorably to 20-25% for conventional and investment property loans.
• Seller standby notes can significantly reduce your out-of-pocket cash by allowing the seller to finance part of your equity injection.
• Total project cost, not just the purchase price, determines your down payment amount.
• Budget for closing costs (2-5% of loan amount) and post-closing reserves beyond your down payment.
• Document all funding sources thoroughly since the SBA requires full paper trails on every source of equity.
