00The financing decision happens before the offer

Most owner-user buyers I work with in Kansas City have one of two reactions when they hear they only need 10% down: disbelief, then suspicion. Both are fair. The 10% number is real — it's the SBA 504 borrower contribution — but it's attached to a structure that takes 90 to 120 days to close, requires personal guarantees, and locks the senior bank into a specific role.,The other end of the spectrum: conventional at 25-30% down, closes in 45 days, no occupancy mandate, and the bank doesn't care what you do with the building three years from now. In between sit SBA 7(a) (faster than 504, more expensive) and USDA B&I (rural-only, longer amortization, cheaper than 7(a)).,Picking the wrong program doesn't kill the deal. It costs you 100-200 basis points over 25 years, or it costs you the deal because the seller picks a faster buyer. This article is the decision tree I walk every owner-user through before we write an offer.

01The Owner-Occupancy Rule

Every government-backed owner-user program starts with the same question: how much of the building will your business actually use?,For existing buildings, the threshold is 51%. For new construction or substantial renovation, it's 60%. This applies to both SBA programs — 504 and 7(a) — and USDA B&I also requires owner-user status. The percentage is measured by rentable square footage, not by revenue or employee count. If you're buying a 20,000 SF building, your operating business needs to occupy at least 10,200 SF on day one.,The good news: you can lease out the other 49%. A lot of buyers don't realize this. You can buy a $4M building, occupy 55%, lease 45% to a tenant, and still qualify for 504 financing. The rental income even helps debt service coverage — it just can't be the dominant revenue source.,Conventional financing has no occupancy mandate. But pricing tightens noticeably on investment loans — typically 50-75 basis points higher rate, lower LTV cap (65-70% vs 70-75%), and tighter DSCR (1.30-1.40x vs 1.25-1.35x). So even on conventional, declaring owner-occupancy gets you better terms.

02SBA 504: The Rate-Sensitive Workhorse

The 504 structure is 50/40/10. Senior bank takes the first 50% at conventional terms (usually 10-year fixed, 25-year amortization). The SBA debenture takes 40% as a second position loan — 25 years fully amortizing, fixed rate for the entire term. Borrower brings 10% down.,Current 504 debenture rates run around 6.5%. That's a 25-year fixed rate, no balloon, no reset. For an owner-user who plans to occupy the building for 15+ years, this is the single most valuable feature in commercial real estate finance. You're locking 40% of your capital stack at a fixed rate for the full amortization period.,The tradeoffs: 90 to 120 days to close (CDC processing plus senior bank), personal guarantees required from all 20%+ owners, prepayment penalty on the debenture (declining over 10 years), and a hard cap on what counts as eligible project costs.,I use 504 when the buyer is rate-sensitive and time-flexible. Deal size sweet spot is $1M to $12M of project cost. Above $12M you can still do 504 — the cap on the debenture portion is $5M (or $5.5M for manufacturing/green) — but the senior bank takes a bigger share and the structure starts to feel less compelling. Below $1M, the closing costs eat the rate advantage.

03SBA 7(a): Speed Over Structure

The 7(a) is a single loan from the bank, with SBA guaranteeing roughly 75% of the loan amount. The bank handles everything — no second CDC loan, no two-stage closing. You can finance up to 90% LTV.,Pricing is the catch. 7(a) loans are typically variable rate, priced as Prime plus a spread (1.0-2.75% currently, capped by SBA). In today's rate environment that's landing in the 9.5-11% range. Compared to a 504 debenture at ~6.5% fixed, you're paying 250-450 basis points more for the SBA-guaranteed portion.,What you buy with that premium is speed and flexibility. 7(a) closes in 60-90 days instead of 90-120. You can roll working capital into the loan (you can't do this with 504). For mixed-use scenarios — buy the building, finance some equipment, fund 12 months of working capital — 7(a) is the only SBA program that does it under one note.,Hard cap: $5M loan size. That puts you at roughly $5.5M to $6M total project cost before you're forced into 504 or conventional. I recommend 7(a) for first-time owner-users buying $500K-$3M buildings where speed matters and they want minimum down payment without splitting the closing across two loans.

04USDA Business & Industry: The Rural Card

Most KC commercial buyers assume USDA is irrelevant because they're in a metro. They're half right. The USDA B&I (Business & Industry) program is restricted to rural areas — defined as populations under 50,000, with specific geographic boundaries that get checked at the property address.,In the KC metro, that knocks out most of Jackson, Johnson, and Wyandotte counties. But several growing submarkets are still eligible: Smithville, Liberty, Excelsior Springs, Kearney, Platte City, Lawson, and most of Cass County south of Belton. I've closed B&I loans in Smithville at 85% LTV with a 25-year amortization on rates 100+ basis points below SBA 7(a). The address eligibility tool on the USDA Rural Development site tells you in 30 seconds whether your target property qualifies.,Structurally, B&I works like 7(a) — single loan, government guarantee to the bank, owner-user requirement. LTV runs 80-90%. Amortization can stretch to 30 years on real estate (longer than SBA's 25). Rates are typically fixed for 5-10 years then adjust, priced lower than 7(a) because the USDA guarantee is structurally different.,I use B&I when the property is rural-eligible, the deal is $2M-$10M, and the buyer wants longer amortization than SBA offers. The closing timeline is similar to 504 (90-120 days) but the rate advantage over 7(a) makes it worth the wait.

05Conventional: When Down Payment Isn't the Constraint

Conventional owner-user financing typically caps at 70-75% LTV. The structure is usually a 5-year fixed rate with a 25-year amortization and a balloon at year five. 10-year fixed terms are available at a premium of 25-50 basis points.,The pitch for conventional isn't the rate or the leverage — both are worse than SBA. It's speed, flexibility, and no occupancy mandate. A conventional loan closes in 45-60 days. There's no CDC, no SBA review, no 8-page eligibility checklist. The bank underwrites the deal, approves it, and funds.,More importantly, conventional gives you optionality. With SBA financing, your occupancy is locked at 51% for the duration of the loan. If your business outgrows the building in three years and you want to lease the whole thing out, you have to refinance to conventional first (and the SBA may require a portion of the proceeds to pay them down). Conventional lets you start as owner-user, convert to investor, and back again, without restructuring the debt.,I recommend conventional for buyers with $1.5M+ cash to deploy, deal sizes above $5M where SBA caps create friction, and any buyer who has a credible plan to convert the building to a leased asset within five years. Also: any buyer who needs to close in under 60 days to win the deal.

The 10% down number is real. The other 90% of the decision is whether you want fixed rate certainty for 25 years, or you want to close in six weeks. You almost never get both.

Note

Underwriting DSCR varies by program and matters as much as the headline LTV. SBA 504 and 7(a) target 1.20-1.25x global DSCR (the operating business plus rental income vs total debt service). USDA B&I sometimes allows down to 1.10x with a strong sponsor and conservative real estate. Conventional banks typically require 1.25-1.35x on owner-user deals, and 1.30-1.40x on investment.,Practical implication: a deal that pencils at SBA underwriting may not pencil at conventional. If you're bumping against 1.20x on the operating business cash flow, you're likely SBA or USDA, not conventional. Run the DSCR math against all four programs before you commit to a structure.

Frequently Asked Questions

Yes — as long as your operating business occupies at least 51% of the rentable square footage (60% for new construction). The other 49% can be leased to third-party tenants, and that rental income actually helps your debt service coverage calculation.

At $2M, 504 gives you a ~6.5% fixed rate on 40% of the loan for 25 years, but takes 90-120 days to close. 7(a) is single-loan, closes in 60-90 days, but the rate is Prime plus a spread — currently 9.5-11% variable. Over 25 years on a $1.4M loan, that rate delta is roughly $400-600K in interest. Use 504 unless speed is critical.

In specific submarkets, yes. Smithville, Liberty, Excelsior Springs, Kearney, Platte City, Lawson, and most of Cass County south of Belton qualify based on rural area definitions. Check the USDA Rural Development address eligibility tool — it's definitive in 30 seconds.

Yes, and it's common. The SBA prepayment penalty on the 504 debenture declines over the first 10 years (starts at 3% in year 1, drops 30 bps per year). After year 10 there's no prepayment penalty. Many owner-users refinance to conventional in years 7-10 when occupancy mandates become inconvenient.
