Yes, you can use a business loan for real estate investing, and which loan fits depends on one question: will your business physically occupy the building, or are you buying it purely to rent out? Owner-occupied purchases open the door to SBA-backed loans with lower down payments and long repayment terms. Pure investment purchases go through conventional commercial mortgages or portfolio loans, with no occupancy strings but tougher cash requirements.
Owner-Occupied or Pure Investment?
This is the fork in the road. The Small Business Administration guarantees loans up to $5 million under the 7(a) program and up to $5.5 million in debentures under the 504 program, but both are designed for businesses that will use the space themselves.1U.S. Small Business Administration. 7(a) Loans2U.S. Small Business Administration. 504 Loans If your plan is to buy an apartment complex, a strip mall, or a warehouse and collect rent, an SBA loan will not work. You need a conventional commercial mortgage.
A mixed plan is possible. If your business will occupy most of the building and you want to lease out the extra space, an SBA loan can still fit, within limits.
SBA Loans When Your Business Will Use the Space
7(a) Loans
The 7(a) program is the more flexible of the two. It covers land, buildings, and equipment, and real estate terms can stretch to 25 years.3Office of the Law Revision Counsel. 15 USC 636 – Additional Powers The SBA guarantees a portion of a loan made by a participating bank rather than lending directly in most cases.4eCFR. 13 CFR Part 120 – Business Loans
Occupancy rules are firm. For an existing building, your business must occupy at least 51%. For new construction funded with 7(a) proceeds, the statute requires you to occupy at least 60% of the total business space and lease no more than 20% to outside tenants.3Office of the Law Revision Counsel. 15 USC 636 – Additional Powers
504 Loans
The 504 program provides long-term, fixed-rate financing for major assets. A Certified Development Company issues a debenture that the SBA guarantees, and that debenture cannot exceed 50% of the total project cost.5Office of the Law Revision Counsel. 15 USC 697 – Development Company Debentures The typical structure is a bank at roughly 50%, the CDC debenture at about 40%, and you at around 10%. Occupancy rules mirror 7(a): at least 51% for existing buildings, at least 60% for new construction.
Commercial Mortgages and Portfolio Loans for Investment Properties
If you will not operate a business out of the property, you are looking at a conventional commercial mortgage. There is no government guarantee, so the lender sets its own rates and standards. Amortization runs 15 to 25 years, but many of these loans include a balloon payment after an initial term of five to ten years. When that comes due, you either pay off the remaining balance or refinance.
Portfolio loans are a subset worth knowing about. The lender keeps the loan on its own books instead of selling it, which gives it room to customize terms, accept unusual properties, or work with borrowers whose files don’t fit standard underwriting. Rates can run slightly higher in exchange for that flexibility.
Which Properties Count as Commercial
Business real estate financing covers property that generates commercial income or houses business operations. The main categories:
- Multifamily buildings with five or more units. These are valued on net operating income rather than comparable home sales.
- Retail: strip malls, standalone stores, shopping centers with multiple tenants.
- Industrial and warehouse: manufacturing plants, distribution centers, storage facilities. Lenders typically require a Phase I Environmental Site Assessment to check for soil or groundwater contamination before approving.6Fannie Mae. Form 4251 – Environmental Due Diligence Requirements
- Office buildings, including medical and professional suites.
- Mixed-use buildings that combine ground-floor retail with residential units above.
One important boundary: properties with one to four residential units are generally excluded from commercial loan programs and are treated as residential lending instead, even when you buy them as investments.7eCFR. 12 CFR Part 723 – Member Business Loans; Commercial Lending A duplex or fourplex rental goes through a residential mortgage, not the products described here.
How Much Cash You Need Up Front
Federal banking regulators publish supervisory loan-to-value ceilings that shape what a bank will lend against different property types:
- Improved commercial property: 85% LTV, so at least 15% down.
- Commercial construction: 80% LTV, at least 20% down.
- Land development: 75% LTV.
- Raw land: 65% LTV.
These are ceilings, not guarantees. Many banks set stricter limits for riskier property types or thinner borrower track records.8eCFR. 12 CFR Part 34 Subpart D – Real Estate Lending Standards SBA loans often require less cash upfront, sometimes as low as 10% for a 504 loan, which is one of the strongest reasons qualifying borrowers choose them.
Interest Rates and Prepayment Penalties
Commercial loan rates are usually quoted as a spread over a benchmark. Since LIBOR was phased out, most variable-rate commercial loans reference the Secured Overnight Financing Rate, which is based on overnight U.S. Treasury repo transactions.9Federal Reserve Bank of New York. An Updated Users Guide to SOFR Some banks still price off the Prime Rate. Fixed-rate options exist, usually with stricter prepayment terms.
Paying off a commercial loan early is rarely free. Common structures include:
- Yield maintenance. You pay the lender a calculated amount that replaces the interest income it would have collected. The penalty is larger when market rates have fallen below your loan rate.
- Defeasance. Instead of paying off the loan, you replace the real estate collateral with government securities that generate enough income to keep making the loan payments. The loan stays open. This shows up most often on loans that have been packaged into commercial mortgage-backed securities.
- Step-down penalties. A simpler schedule such as 5% in year one, 4% in year two, and so on.
SBA 7(a) loans charge a prepayment penalty only if you pay off 25% or more of the balance within the first three years.1U.S. Small Business Administration. 7(a) Loans
How Lenders Decide
Commercial underwriting relies on the property’s ability to pay for itself. The central metric is the Debt Service Coverage Ratio: net operating income divided by annual loan payments. Most lenders want a DSCR of 1.20 to 1.35, meaning the property produces 20% to 35% more income than the mortgage costs. Multifamily can qualify near 1.15, and hotels or specialty properties often need 1.40 or higher.
Lenders also run a global cash flow analysis that combines your business income, related entities, and personal finances. If you already own investment property, expect to submit a Schedule of Real Estate Owned listing each property’s value, mortgage balance, rental income, and expenses.
Plan on producing two to three years of business and personal tax returns, current profit and loss statements, a balance sheet, and entity documents (Articles of Organization and Operating Agreement for an LLC; Articles of Incorporation and bylaws or a board resolution for a corporation). You will also sign IRS Form 4506-C so the lender can pull tax transcripts directly from the IRS.10Internal Revenue Service. Income Verification Express Service (IVES) A commercial appraisal runs roughly $2,000 to $4,000 and can take several weeks. Underwriting and appraisal together often take four to six weeks for a straightforward deal.
Personal Guarantees and Recourse
Nearly every commercial real estate loan for a small or mid-size investor requires a personal guarantee. Your personal assets stand behind the debt.
With a recourse loan, the lender can pursue your personal assets if the collateral property doesn’t cover the debt after foreclosure.11Internal Revenue Service. Recourse vs Nonrecourse Debt Most smaller-investor loans are full recourse. Non-recourse loans limit the lender to the collateral itself and are generally reserved for larger deals with strong borrowers and low leverage. Even non-recourse loans contain “bad boy” carve-outs: filing bankruptcy, fraud, misapplying loan proceeds, or transferring the property without lender consent can convert the loan back to full recourse.
A note on spouses. Under the Equal Credit Opportunity Act, a lender cannot require your spouse to guarantee the loan just because you’re married. If jointly owned property is being pledged as collateral, though, the lender can require your spouse to sign the security agreement to create a valid lien, without requiring them to sign the promissory note or take on personal liability.12Consumer Financial Protection Bureau. Comment for 1002.7 – Rules Concerning Extensions of Credit Some state laws require both spouses to sign the note for the lien to be enforceable, which can override that protection in practice.
Tax Consequences Worth Knowing Before You Sign
Depreciation and Recapture
Commercial buildings can be depreciated over their useful life, cutting your taxable income each year you own the property. When you sell, the IRS recaptures the benefit. Gain attributable to the depreciation you claimed is taxed as unrecaptured Section 1250 gain at ordinary income rates up to a maximum of 25%, higher than the long-term capital gains rate that applies to the rest of the profit.
1031 Like-Kind Exchanges
You can defer tax on the sale of investment real estate by exchanging it for a like-kind replacement property under Section 1031. The deadlines are strict. You must identify the replacement property in writing within 45 days of the sale and close within 180 days (or by your tax return due date, whichever comes first). Missing either deadline kills the exchange, and the IRS does not grant extensions outside declared disaster areas. Property held primarily for resale, like a flip, does not qualify.13Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment
Business Interest Deduction Limits
Interest on a commercial real estate loan is generally deductible, but Section 163(j) caps the amount of business interest you can deduct in a year at 30% of your adjusted taxable income plus any business interest income. Small businesses with average annual gross receipts at or below the inflation-adjusted threshold ($31 million for 2025) are exempt.14Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense A business that qualifies as a real property trade or business can also elect out of the cap, but doing so forces it to use the alternative depreciation system, which slows depreciation deductions going forward.
