SBA loans in South Dakota: low rates, heavy 504 use, and how to approach lenders

Cheaper money, and more of it fixed

South Dakota's median 7(a) loan, $150,000, is almost exactly the national median. Its pricing is not. The median rate at approval was 9.25%, a full point under the national 10.25%, and the middle half ran from 8% to 10.5%. Acquisition loans priced lower still, at a median of 8.5%. Loan size does not explain it: the typical South Dakota loan sits in the same SBA cap tier as the typical loan nationwide. The difference is in what lenders chose to charge, which suggests competition for good credits among the state's 58 active lenders, though the data do not show why each lender priced as it did.

The fixed-rate share, 41.6%, means two South Dakota loans in five carried a payment that cannot rise. A fixed rate costs something at the outset but removes the risk that a rising base rate erodes coverage over a ten-year term. Lenders here plainly offer that choice, and a borrower should ask for both quotes. Fixed vs variable rate business loans and the SBA loan rates page cover the trade-off.

A 504 state

South Dakota recorded 213 SBA 504 loans at a median of $518,000, against 361 7(a) loans. That is more than half the 7(a) count. Owners who buy the buildings they operate from are using the program designed for that.

504 finances owner-occupied real estate and long-life equipment in three pieces: typically 50% from a bank in first position, 40% from a certified development company in second, and 10% from the borrower. The borrower's share rises to 15% for a new business or a special-purpose property, and to 20% for both. The CDC's share goes up to $5 million, or $5.5 million for manufacturers and energy projects, and since July 2026 the 504 and 7(a) limits are counted separately, so a business can use both. The business must occupy at least 51% of an existing building, or 60% of new construction.

With so many start-ups in the 7(a) figures, the 15% tier matters: a new business building its first facility will need more equity than an established one buying its current premises. The CDC portion carries a fixed rate over a long term, which gives a property buyer a fixed payment on a large part of the project. SBA 7(a) vs SBA 504 and SBA 504 vs a conventional commercial mortgage compare the routes, and refinancing with SBA 504 covers moving an existing mortgage into the program.

Start-ups, franchises and quick-service food

Start-ups made up 23.5% of South Dakota loans, nearly one in four, and franchises 11.6%. The top industries by loan count fit that picture: limited-service restaurants (19 loans), snack and nonalcoholic beverage bars (15), local general freight trucking (13), fitness and recreational sports centers (11) and full-service restaurants (10). Quick-service food, coffee counters and gyms are the kinds of business a new owner opens, often under a franchise.

A start-up has no history for a lender to measure, so the file carries the weight: a business plan and use-of-proceeds narrative, projections with the assumptions stated, and an owner resume that supports the management experience SBA asks about on Form 1919. For a start-up, SBA requires an equity injection of at least 10% of total project costs, and many lenders expect more. A franchise brings a system a lender can compare against other units, which helps, and the lender will read the franchise agreement for the controls the franchisor keeps over the unit. See SBA loans for limited-service restaurants and SBA Form 1919.

Trucking and the farm economy

Local freight trucking is the one industry in the top five that is not a consumer concept. In South Dakota much of it hauls grain, livestock, feed and building materials, so the revenue follows harvests and the farm economy. A lender will read the trucking company's revenue by customer and by month, look at the age and financing of the fleet, and ask how the business did in a weak crop year. Trucks are collateral, but their value falls quickly, and a lender will lean on cash flow more than on the fleet. SBA loans for local trucking and financing a trucking company acquisition go further.

The same exposure reaches businesses that never touch a farm. A restaurant or gym in a small South Dakota town depends on local spending, and local spending depends on farm income. Lenders do not ask for crop prices, but they do look at whether revenue held up in the weaker years, which is another reason to show more than one year.

Buying a South Dakota business

Lenders approved 51 acquisition loans, 14.1% of the state's total against 10.4% nationally, at a median of $550,800 and a median rate of 8.5%. That median is above the $350,000 line where SBA caps the spread at the base rate plus 3%, and well above the $250,000 threshold for an independent business valuation, which applies when the amount financed, less appraised real estate and equipment, exceeds $250,000. The loan for the purchase cannot exceed the valuation.

The rest of the rules are national. The buyer injects at least 10% of total project costs, and a seller note counts for up to half of that only on full standby for the life of the SBA loan. SBA prohibits an earnout to the seller. From 1 October 2026 a change of ownership must show 1.25x coverage on historical results, needs financial due diligence, and amortizes over no more than 10 years except the real estate share. SBA 7(a) business acquisition loans and a business acquisition with real estate set out the structure.

South Dakota has no personal or corporate income tax, which simplifies one part of the file: for owners who live in the state, the personal tax returns are federal returns only, and the lender's global cash flow test, 1.0x including the owners, is read from those. It does not change the lender's other tests.

When conventional debt is the better answer

When SBA loans already price low, the rate advantage of the guaranty matters less, and SBA's costs weigh more: the guaranty fee, the program paperwork, personal guarantees from every 20% owner and, on loans of 15 years or more, a prepayment charge: prepaying more than 25% in any of the first three years costs 5% of the prepaid amount in year one, 3% in year two and 1% in year three. An established South Dakota company with property, equipment and coverage above the 1.25x conventional banks commonly look for may do better without the guaranty.

Transparent's lender book holds 1,800+ lenders: 278 write SBA 7(a) and 504, 1,148 write conventional term and private credit, and 244 write equipment. A South Dakota file, with its tax returns, P&L, balance sheet, debt schedule and a personal financial statement for each 20%+ owner, can be priced against all three at once. Transparent charges nothing before a loan closes, and on SBA loans the lender pays Transparent, not the borrower.
