How much of a building do I have to occupy for an SBA loan?

For an existing building, your business generally must occupy at least 51% of the rentable space. For new construction, the requirement is higher, generally 60%. Lenders apply the rules to your specific deal, so confirm with your lender.

Can I lease out part of a building I buy with an SBA loan?

Yes, as long as your business still meets the occupancy requirement. In an existing 10,000 SF building, you could occupy 6,000 SF (60%) and lease the other 4,000 SF to tenants.

Can I use an SBA loan to buy an investment property?

No. SBA 504 and 7(a) real estate financing is for owner-occupied property used by the operating business. Property bought mainly to lease to others is investment property and needs conventional or other financing.

Does rental income from the space I lease out help my loan?

It can help cover the mortgage, and some lenders consider it in underwriting, but treatment varies by lender. Ask your lender how it will count existing or projected leases.

Owner-Occupied vs Investment Property for SBA

The short answer Owner-occupied property is a building your own operating business uses; investment property is held to lease to others. For SBA 504 and 7(a) loans, your business generally must occupy at least 51% of an existing building's rentable space, or 60% for new construction.

Worked example (illustrative numbers)

An existing 10,000 SF building. Your business occupies 6,000 SF and leases 4,000 SF to a tenant.
Occupancy: 6,000 ÷ 10,000 = 60%. That meets the 51% rule for an existing building.

If you occupied only 5,000 SF: 5,000 ÷ 10,000 = 50%, below 51%, so the deal would generally not qualify. To reach 51% you need at least 10,000 × 0.51 = 5,100 SF.

On new construction of the same size, the 60% rule means at least 10,000 × 0.60 = 6,000 SF.

Why does occupancy matter for SBA loans?

SBA loans exist to help operating businesses, not real estate investors. The occupancy rule is how lenders confirm the building is primarily for your business. If you qualify, a 504 loan typically finances about 50% through a bank, about 40% through a Certified Development Company (CDC) and about 10% from you. Startups or special-purpose properties typically need 15% down, and 20% if both apply.

What is the difference between 504 and 7(a)?

The 504 program finances fixed assets like real estate and major equipment. The 7(a) program is more flexible and can also include working capital, equipment and business acquisition. Both generally apply the same occupancy rules to real estate. We compare them in SBA 504 vs 7(a) for buying your building.

How is occupied space measured?

Lenders generally look at rentable square footage your business uses, including your office, warehouse and storage. How shared areas and future expansion space are counted can vary. Rules and terms vary by lender, so confirm the calculation with your lender before you make an offer.

How this affects your purchase

Pick a building sized so your business clears 51% (or 60% for new construction) now.
Leasing the rest can offset your mortgage, but plan for vacancy.
Check existing leases: a building fully leased to others may not free up enough space for you.
Build a financing contingency into the letter of intent.
A flex condo can be a smaller way to own space you fully occupy.
