The SBA 504 is the reason small businesses in the Salt Lake Valley can buy industrial buildings with about 10% down instead of the 30% a conventional loan wants, and most of the owner-user purchases we work on run through it. It is also a program with rules, paperwork, and a clock, and buyers who learn those after falling in love with a building lose deals to buyers who learned them first.
THE SHORT VERSION
- The structure: a bank lends about 50%, a CDC funds about 40% through the SBA, and you bring roughly 10% down
- The tradeoff: a long fixed rate on the CDC portion in exchange for more paperwork and a longer runway than conventional
- The occupancy rule: your business occupies at least 51% of an existing building, and you can lease out the rest
- 504 vs 7(a): the 504 is built for real estate; the 7(a) is the general-purpose tool that sometimes wins on speed or bundling
- The play: get pre-qualified before you tour, because prepared buyers close here in 60 to 90 days
Here is the deep version of what we compress into one section of the buying guide: how the program is built, when its sibling program wins instead, where the occupancy rules bend, and what the process actually asks of you.
How an SBA 504 loan is structured (the 50/40/10 split)
Three parties fund the purchase. A bank makes a first-position loan of roughly 50% of the project. A Certified Development Company, a nonprofit lender licensed by the SBA, funds roughly 40% behind it. You bring about 10% down.
Treat this as illustration math, not a quote, and here is what that looks like on a round number:
| Slice | Who funds it | On a $1,000,000 project |
|---|---|---|
| Bank first mortgage | Your bank, priced and termed like any commercial loan | $500,000 |
| CDC debenture | The CDC through the SBA, long fixed rate | $400,000 |
| Down payment | You | $100,000 |
A conventional commercial loan at a typical 30% down wants $300,000 from you on that same building. The $200,000 difference stays in the business, buying inventory, people, and equipment, which is the entire argument for tolerating the extra paperwork.
$200,000
What a 10% down payment leaves in your business on a $1,000,000 purchase, against the conventional 30%. Illustration math on a round number, not a quote.
The CDC piece is what makes the program worth that paperwork: it carries a long fixed rate, which means the largest slice of your payment behaves like rent that never gets a renewal bump. The bank portion is priced and termed by the bank, so that half of the deal still gets shopped like any commercial loan.
Project cost can include more than the purchase price. Certain improvements, equipment with a long life, and some soft costs can roll into the project number, which matters when the building needs work on day one. Your CDC walks the specifics, and this is one of several places where the answer is always confirm current terms with your CDC rather than a blog post, including this one.
Two situations raise the down payment: a business under two years old, or a special-purpose building, each add about 5%. General warehouse buildings do not sit on the SBA's special-purpose list, which is why 10% is the number that shows up in practice.
One more lever most buyers never hear about: the seller can carry part of the down payment. The 504 allows seller financing to count toward your contribution, and on the right deal a motivated seller will carry a real piece of it. Where it works best is a buyer who has the cash but wants it going into the building on day one, power, dock equipment, office buildout, the improvements that make the space actually run. That version is also the easiest one to sell to the seller: their note sits behind the bank and the CDC, and the strongest thing securing it is a building you are actively improving with the cash they freed up. A seller carry is a negotiated term, and the ask lands differently when it comes with a scope of work attached. Raise it in the pre-qualification conversation, then let your broker negotiate it into the LOI.
504 vs 7(a) for a building purchase
The SBA runs two main programs and buyers mix them up constantly. The insider shorthand: the 504 is the real estate tool, the 7(a) is the Swiss Army knife.
The 7(a) is the SBA's general-purpose loan. It can fund working capital, business acquisition, equipment, and real estate, all in one facility, and it often moves faster because one bank runs the whole show. The tradeoff is structure: 7(a) real estate deals commonly carry variable or shorter-fixed pricing, and the long fixed CDC piece that defines the 504 is not part of it.
When does the 7(a) win for a building? Usually when the building is part of a bigger transaction, like buying a business and its real estate together, or when speed beats rate stability and the buyer plans to refinance later. When the purchase is the building itself and the buyer plans to stay, the 504's fixed piece is hard to argue with. Your lender and CDC will pressure-test which fits, and the right move is asking that question in the pre-qualification conversation, not at the LOI.
Side by side:
| SBA 504 | SBA 7(a) | |
|---|---|---|
| Built for | Real estate and long-life equipment | General purpose |
| Rate on the SBA piece | Long fixed, through the CDC | Commonly variable or shorter fixed |
| Who runs it | A bank plus a CDC | Usually one bank |
| Speed | Longer runway | Often faster |
| Wins when | You are buying the building and staying | The real estate rides along with a business acquisition, or speed beats rate stability |
The 51% occupancy rule and where it bends
The rule everyone quotes: your business must occupy at least 51% of an existing building. The parts that decide real deals live in the edges.
The rest is income. You can lease out the other 49%, which is how plenty of owner-users cover a third of their mortgage with a tenant, and how more than one of our clients became a landlord by accident. Buy a 10,000 SF building, run your shop in 6,000, and the tenants in the other 4,000 help carry the note.
Tenants in place can stay. Buying a building with existing tenants works as long as your occupancy clears the bar, and a seasoned tenant with term left is underwriting help, not a problem.
New construction runs on a different number. Ground-up projects require your business to occupy about 60% initially, with a plan to grow into more over time. If your path is building rather than buying, the occupancy math changes with it.
Entity structure matters early. The standard setup is real estate in one entity and the operating business paying it rent, and the loan is underwritten around that structure. Set it up with your CPA before closing, not after.
Is an SBA 504 payment cheaper than leasing?
The question every owner-user actually asks: will the payment beat my rent? Three or four years ago the answer here was often yes. Debt was cheaper, building prices had not caught up, and plenty of buyers ended up with debt service under the lease payment they left behind. Rates and pricing have both moved since, and the honest answer today is that the two usually land close, with the mortgage often slightly higher.
Close is not the same as equal, because the two payments do different things. A slice of every mortgage payment pays down principal, which is money you keep. The CDC portion is fixed for decades, while a lease resets to market at every renewal. And the building's appreciation belongs to you, which along the Wasatch Front has been a real number for a long time.
Here is the part the sticker comparison misses: if you lease warehouse space today, you are almost certainly on an NNN lease, which means you already pay the property taxes, insurance, and common-area costs. Owning does not add those. What it adds is the capex you used to call the landlord about, the roof, the HVAC replacement, the parking lot, and that responsibility is real. The clean comparison is your current all-in occupancy cost against debt service plus a reserve for those items, and that math depends on the building, your rate on the bank half, and the rent you pay now. That is a fifteen-minute exercise with real numbers, and it is exactly what the pre-qualification conversation is for.
What documents the CDC needs from you
The 504 file is thicker than a conventional file, and buyers who show up with it ready move like cash buyers. Expect to produce two to three years of business and personal tax returns, current interim financials, a personal financial statement, entity documents, and, if the numbers are tight, projections that show the payment working.
The good news is that the first conversation costs nothing and settles most of it. Mountain West Small Business Finance, the CDC we refer clients to most, can pre-qualify a buyer in one conversation, and walking into your first tour already pre-qualified is the single biggest speed advantage a buyer can have in this market. Sellers read prepared buyers the way lenders do.
How long an SBA 504 purchase takes
A financed purchase here realistically runs 60 to 90 days from LOI to closing, with the SBA process setting the pace, and that number assumes the financing conversation started before the touring did. Start the paperwork after you find the building and you hand every prepared buyer in the market a head start on your deal.
Conventional financing is the comparison to know. The Architectural Components building at 9387 South 670 West in Sandy went under contract to closed in 32 days on conventional debt, the fastest shape a financed deal takes here. That speed is what the 504 trades away for the smaller down payment, and for most owner-users, keeping $200,000 in the business is worth the longer runway.
The order that works: pre-qualify first, tour second, write the LOI third. It is the same sequence the buying guide preaches, and the 504 is the reason it exists.
Common questions
How much do I need down on an SBA 504 warehouse purchase?
About 10% of the project on a standard deal. A business under two years old or a special-purpose building each add roughly 5%, and project cost can include certain improvements and soft costs beyond the price. Confirm the current structure with your CDC.
Can the seller help with my SBA 504 down payment?
Yes. Seller financing can count toward your required contribution on a 504, and on the right deal a seller will carry a meaningful piece of it. The note sits behind the bank and CDC and the structure gets underwritten as a whole, so raise it early with your CDC and let your broker negotiate it into the LOI.
Can I rent out part of a building I buy with a 504?
Yes. On an existing building your business must occupy at least 51%, and the rest can be leased out, which is how many owner-users cover part of their payment. New construction requires about 60% occupancy with a plan to grow into more.
Should I use a 504 or a 7(a) to buy a building?
For a straight building purchase where you plan to stay, the 504's long fixed CDC portion usually wins. The 7(a) competes when the real estate rides along with a business acquisition or when speed matters more than rate stability. Ask both questions in your pre-qualification conversation.
How long does an SBA 504 purchase take?
Realistically 60 to 90 days from LOI to closing on a financed deal, with the SBA process setting the pace. The CDC can pre-qualify you in a single conversation, and doing that before you tour is what keeps the clock from costing you the building.
Do I apply directly with the SBA?
No. You work with a bank and a CDC, and they run the SBA process. In practice the CDC quarterbacks the program side, which is why the pre-qualification conversation is the real starting line.
Here is the market context that makes the preparation worth it: owner-user buildings in this valley do not come to market on a schedule. They come to market when an operator retires, outgrows the floor, or relocates, which means supply shows up one building at a time and sells to whoever was ready that week. What is listed publicly today sits on warehouses for sale in Salt Lake City. Readiness is three things: a pre-qualification letter, your entity documents, and a spec sheet of what your operation actually needs. All three cost a few conversations and zero dollars.
If a purchase is anywhere on your one-year horizon, the work starts now. Have the CDC conversation, then call me with what you run and what you need on the floor. Some of the best purchases here never hit a listing site, they happen because a ready buyer existed and we called the right owner. When the right building shows up, you will be the buyer who was ready.
Thinking about buying in the next year?
Tell me what your company does and what you need in a building. I'll tell you which lender path makes sense and send you buildings as they come up, including the ones that never hit the listing sites.
