Buying the building your business already occupies is the most common real estate transaction in SBA lending, and it is the one the programs were most clearly designed for. The logic is straightforward: the business is already paying rent, the rent is already underwritable cash flow, and converting that payment into equity in an asset the owner controls is a defensible use of long-term debt.
What surprises operators is how different the underwriting feels from an investment property. Nobody is analyzing market rents or a rent roll. The analyst is looking at whether your operating business can carry the mortgage payment, which means the building is being underwritten on the strength of the company inside it. That reframing changes what you should prepare.
The occupancy requirement
The distinction between an eligible owner-occupied purchase and an ineligible investment property comes down to occupancy. For an existing building, the operating company must occupy a majority of the rentable square footage (commonly cited as at least 51 percent) with the remainder available to lease to third parties. For new construction the initial occupancy requirement is higher, with a plan to occupy a larger share over time.
The specific percentages and the timelines attached to them are set by SBA policy and should be confirmed for the current rule set. What does not change is the principle: the loan finances a building that houses a business, not a business of owning buildings.
The two-entity structure
Almost every owner-occupied SBA deal uses two entities: an operating company that runs the business and a holding company that owns the real estate. The holding entity is typically the borrower for the mortgage, the operating company leases the space, and both are obligated on the loan: usually as co-borrowers, with the operating company's cash flow supporting the debt.
This structure is normal, expected, and generally motivated by liability and estate planning rather than by SBA rules. What SBA cares about is that the two entities have common ownership, that the lease between them is documented on reasonable terms, and that the rent is not set at a level that distorts either entity's financials.
How the intercompany rent is treated
In the cash-flow model, the analyst typically consolidates the two entities, removing the intercompany rent so the mortgage payment is measured directly against the operating company's earnings. That is the number that matters, and it is worth computing yourself before you make an offer.
One consequence catches owners off guard: setting the intercompany rent artificially high to shift income into the holding entity does not improve the file. The analyst removes it either way, and an unusual rent invites questions about whether the operating company can genuinely support the occupancy cost. Document the lease at a defensible market figure and let the consolidated numbers speak.
Rent versus own, honestly
The pitch for buying is usually that the mortgage payment resembles the rent. Sometimes it does. But ownership carries costs a triple-net tenant may already pay and a gross tenant does not: property tax, insurance, maintenance, capital repairs and the reserve you should be funding for a roof you will eventually replace.
| Line item | Leasing | Owning |
|---|---|---|
| Base occupancy cost | $108,000 rent | $118,000 debt service |
| Property tax and insurance | Often in rent | $28,000 |
| Maintenance and reserves | Largely landlord | $15,000 |
| Total annual cash cost | $108,000 | $161,000 |
| Principal reduction (year 1) | $0 | About $26,000 |
| Escalation risk | Rent resets at renewal | Fixed or capped on the debt |
The example above deliberately makes ownership look expensive in year one, because in cash terms it often is. The case for owning is not the first year. It is the absence of a rent escalation every renewal, the principal reduction accumulating each month, and the fact that in year twenty the payment stops entirely while rent would not have. Underwrite the first year honestly and hold for the long one.
Appraisal and environmental review
Two third-party reports drive the real estate timeline. The appraisal is ordered by the lender from an independent panel (you cannot supply your own) and SBA requires an independent appraisal for commercial real estate above a stated dollar threshold. If the appraised value comes in below the purchase price, the loan is sized against value, and the difference becomes a negotiation with the seller or additional cash from you.
Environmental review starts with a records search and risk assessment. Depending on the property's history and the industries that have operated there, it may escalate to a full site assessment and occasionally to subsurface investigation. Properties that have housed gas stations, dry cleaners, auto repair, machine shops or any manufacturing with solvents routinely escalate, and escalation adds both time and cost.
Which program for the building
If the transaction is purely real estate and the property is general-purpose, 504 usually deserves the first look, because the debenture portion carries a long fixed rate and the blended cost is frequently lower. If the deal includes working capital, equipment, buildout or the purchase of the business itself, 7(a) handles all of it in one note with a blended maturity.
Special-use properties: those with limited alternative uses, such as certain hospitality, medical or industrial assets: carry higher injection requirements in both programs, because the collateral is worth less to anyone other than you. Factor that into your cash planning early.
Preparing the file
Owner-occupied real estate document set
- Purchase agreement with a closing date that allows for appraisal and environmental turnaround.
- Current lease for your existing premises, including remaining term and any termination penalty.
- Square footage breakdown showing what your business will occupy versus what will be leased out.
- Any existing tenant leases, with rent roll and lease expirations.
- Prior appraisal, survey, title work or environmental report if the seller has them.
- Property tax bills and insurance quotes for the specific building.
- Estimates for any planned buildout or improvements, with contractor documentation.
- Entity documents for both the operating company and the holding company.
- Draft lease between the two entities on documented, reasonable terms.
The item borrowers most often skip is the tax and insurance detail on the specific property. Underwriting will build them into the payment analysis regardless, and a guess that turns out to be low is a coverage problem discovered late.
Can I count the rent from other tenants as income?
It is generally considered, but conservatively, and it is not the primary repayment source. The loan is underwritten on the operating company's ability to carry the payment, with tenant income treated as support rather than the basis of the credit. Do not build a purchase around tenant income you need in order to clear coverage.
What if the appraisal comes in low?
The loan sizes to the lesser of purchase price and appraised value, so the gap becomes yours to solve: usually by renegotiating the price, increasing your injection, or walking. This is why an appraisal contingency in the purchase agreement is worth insisting on, particularly in markets that have moved quickly.
Do I have to own the property in a separate entity?
Not required, but common, and usually driven by liability and estate considerations rather than by SBA. What matters to the lender is that ownership across the entities is consistent, both are obligated appropriately, and the intercompany lease is documented on terms that do not distort either set of financials.
Can I build rather than buy?
Yes. Ground-up construction and major expansion are financeable under both programs, with construction-period disbursement controls, a higher initial occupancy requirement, and generally an interest-only period during construction. Expect more documentation, more inspection and a longer overall timeline than an existing-building purchase.
How much do I need to put down on a building?
It depends on the program, the property type and the lender. General-purpose property with an established operating company typically requires the least; special-use property and newer businesses require more. Ask for the injection requirement on your specific property type before you make an offer, because it moves the cash you need materially.
Can I refinance a building I already own into an SBA loan?
In defined circumstances, yes, under refinance provisions that exist in both programs subject to eligibility conditions on the existing debt. The rules here have been amended several times, and whether your specific loan qualifies depends on its age, terms and how the original proceeds were used. Bring the existing note and payment history to the first conversation.
Where to start
Compute your true occupancy cost today (rent plus everything you pay on top of it) and compare it against a modeled mortgage payment plus tax, insurance and a real maintenance reserve. If the gap is manageable and you intend to be in the building for a decade, the transaction is worth pursuing seriously.
Then ask two questions before you sign: what was on this site before, and how much of the building will my business actually occupy. Those two answers determine your timeline and your eligibility. Bring them to the intake with your operating company's returns and the file starts on solid ground.
