Owner-user CRE has three primary tracks: SBA 504 (50/40/10 with 25-year fixed CDC tranche), SBA 7(a) (single loan up to $5M), and conventional bank perm. Sale-leaseback and CTL convert real estate into long-tenor capital priced off the tenant's corporate bond curve. 1031 exchanges require equal-or-greater debt at replacement.
Why owner-user, SLB, CTL, and 1031 belong in the same financing discussion
These four structures share a common DNA that separates them from generic investor-deal financing: the operating business's credit and the real-estate underwriting are linked. An owner-user loan underwrites the operating company. A sale-leaseback or credit-tenant lease prices off the tenant's corporate bond curve. A 1031 exchange ties replacement-property debt sizing back to the relinquished property's debt, a tax-driven constraint, not a credit-driven one. None of these decisions can be made in a vacuum: the right answer almost always lives at the intersection of capital cost, balance-sheet strategy, and tax outcome.
Per FDIC Quarterly Banking Profile, small-business owner-occupied CRE has been one of the more resilient bank-loan categories through 2024 to 2026, and bank appetite for owner-user paper remains stronger than for investor CRE in most markets. Per NAREIT data, net-lease REIT activity in single-tenant retail and industrial has continued to grow as operating businesses open real-estate equity to fund operations.
This pillar is not tax or legal advice. SBA program rules, IRS 1031 mechanics, CTL structuring, and SLB accounting (ASC 842 lease classification) all require professional counsel before structuring any specific deal.
Owner-user financing, SBA 504 vs. SBA 7(a) vs. conventional
SBA 7(a) is the alternative for sub-$5M deals or where multi-purpose use of proceeds (working capital + equipment + real estate) is needed. Up to 90% LTC, 25-year amortization, partial 75% to 85% SBA guarantee, prime + 2.25% to 2.75% variable (~10% in 2026). Closes faster than 504 with a Preferred Lender (60 to 90 days), more flexibly structured, but does not offer the long-fixed CDC tranche.
Conventional bank perm is the third path: 60% to 70% LTV, 1.20x to 1.35x DSCR, 5/10 yr fixed via swap or fixed long-bond, 20 to 25 yr amortization, full recourse with deposit relationship. Best for borrowers above SBA caps, who do not need the SBA leverage, or who want fastest execution (60-day close possible with an existing bank relationship).
Decision factors: deal size (sub-$5M favors 7(a), $5M to $15M favors 504, $15M+ leans conventional), leverage need (90% LTC favors 7(a), 90% combined LTC favors 504, sub-70% favors conventional), rate certainty preference (long fixed favors 504), and timing (60 to 90 days favors 7(a) PLP, 90 to 120 days favors 504, 60 days favors conventional). The owner-user SBA sizing tool walks the math step by step.
Sale-leaseback and credit-tenant lease: capital off the tenant's bond curve
A sale-leaseback (SLB) is a transaction where an operating business sells its real estate and leases it back long-term, typically on triple-net (NNN) terms. SLB opens 100% of real-estate equity, converts owned real estate to a lease liability (ASC 842), and frees up balance-sheet capacity for operating investment. Pricing is set by the cap rate the buyer accepts on the lease, which is a function of tenant credit, lease term, escalations, and asset quality.
Credit-tenant lease financing evaluates the tenant’s credit, lease obligations and real estate. Compare the proposed loan with other financing options using the complete terms.
Per NAREIT net-lease data, single-tenant net-lease cap rates in 2026 sit in the 5.5% to 7.5% range for investment-grade retail and industrial tenants on long leases (15+ years), widening to 7.5% to 10%+ for sub-investment-grade tenants and shorter leases. Dark-store risk, tenant bankruptcy or vacate during the lease term, remains the largest underwriting concern on retail SLB and CTL deals.
1031 exchange debt mechanics
Per IRS Section 1031, a like-kind exchange of real estate held for investment or productive use in a trade or business defers the recognition of capital gain. A common misconception: 1031 only requires equal-or-greater value at replacement. Reality: the rules require both equal-or-greater value AND equal-or-greater debt (or additional cash to cover the debt shortfall). Boot, receipt of cash or other non-like-kind property, triggers immediate recognition of gain.
Debt replacement is the most-overlooked piece of 1031 deal sizing. If the relinquished property had $5M of debt and the replacement property has $4M of debt, the $1M shortfall creates mortgage boot taxable as gain, unless the sponsor adds $1M of additional cash equity at closing.
Delaware Statutory Trust (DST) structures let 1031 sponsors place exchange equity into a fractional interest in a larger institutional asset. The DST sponsor places debt at the entity level; the 1031 investor's share of that debt counts toward the investor's debt-replacement requirement. DST debt is typically 50% to 60% LTV, 7 to 10 yr fixed, non-recourse to the investor, coordinated with the 45-day identification and 180-day close window.
Owner-user imputed rent and dark-store underwriting
Owner-user borrowers don't pay external rent, but lenders underwrite an imputed rent (market rent on the space) to compute a hypothetical DSCR independent of the operating business. The imputed-rent test is a backstop: even if the operating business fails, would the real estate cash-flow on a market-rent basis at the loan's debt service? Per SBA SOP 50 10, this test is part of the 504 / 7(a) underwriting; conventional banks apply it informally on owner-user deals.
Dark-store risk is the inverse problem on net-lease and CTL deals: if the tenant goes dark (vacates while continuing to pay rent), the replacement-tenant economics may be far below the existing rent. Lenders model dark-store re-tenanting cost (TI/LC, downtime, rent re-set) into the LTV and stress-DSCR test. Single-tenant retail in challenged categories (drug stores, large-format big-box) trades wider on dark-store risk concerns.

Frequently asked questions
When should an owner-user choose SBA 504 vs. SBA 7(a)?
504 is the long-fixed-rate workhorse for $5M to $25M+ deals where the 25-year CDC debenture matters. 7(a) is the single-loan, faster-to-close, multi-purpose-of-proceeds option for sub-$5M deals. For $5M to $10M, the choice often comes down to whether the borrower needs working capital folded into the loan (favors 7(a)) or wants the long fixed CDC tranche (favors 504).
Does a sale-leaseback replace conventional owner-user debt?
It replaces it entirely. SLB converts owned real estate to a lease, there is no debt on the company's balance sheet from the real estate. The trade is real-estate equity for a long-term rent obligation that runs through the income statement, not the balance sheet (ASC 842 lease accounting added the lease asset/liability, but the economics are still rent vs. debt service).
Why is CTL financing typically cheaper than real-estate financing?
Tenant credit and lease terms can influence a credit-tenant lease loan. They do not establish a universal rate advantage over a conventional mortgage.
How does 1031 debt replacement actually work?
The replacement property must carry equal-or-greater debt than the relinquished property, or the sponsor must contribute additional cash equity to cover the shortfall. A debt shortfall not covered by cash creates mortgage boot, taxable as gain. The 1031 debt replacement calculator walks the side-by-side.
What is dark-store risk in net-lease underwriting?
The risk that a tenant vacates during the lease term while continuing to pay rent (going dark). Replacement-tenant economics may be far below existing rent, so lenders model the re-tenanting cost (TI/LC, downtime, rent re-set) into LTV and stress DSCR. Drug-store and large-format big-box categories trade wider on dark-store concerns.
