Using Seller Credits for 2-1 Rate Buydowns and SDHDA Closing Costs in South Dakota — Prairietally
Updated October 2026
A South Dakota seller offering $10,000 toward closing costs gives the buyer a budgeting decision, not unrestricted cash. The best allocation depends on allowable expenses, loan-program contribution limits, available assistance, and whether the household values lower upfront costs or temporary payment relief.
What a 2-1 buydown actually changes
With a typical 2-1 temporary buydown, a funded account subsidizes the principal-and-interest payment as though the rate were two percentage points lower during year one and one point lower during year two. Beginning in year three, the borrower pays the full scheduled principal-and-interest amount.
The mortgage note rate does not change. Taxes, insurance, and association charges are not reduced by the buydown and can increase independently. Borrowers generally must qualify using the full note-rate payment rather than the temporarily subsidized amount.
Compare today's rates and a full-payment scenario in the monthly payment calculator. The Consumer Financial Protection Bureau offers resources for comparing mortgage costs beyond the initial payment.
Coordinate credits with South Dakota Housing
South Dakota Housing offers the First-Time Homebuyer Program, Repeat Homebuyer Program, and Fixed Rate Plus assistance options of 3% or 5% for down payment and closing costs. Confirm current eligibility, repayment terms, participating-lender requirements, and compatibility with any temporary buydown.
Also ask how Homeownership Education Resource Organization (HERO) credits apply to your transaction, including qualifying education and lender procedures. Do not count an anticipated credit until its availability and treatment are confirmed.
A useful allocation sequence is:
- Identify the required borrower contribution and eligible assistance.
- Cover allowable lender charges, settlement costs, prepaids, and escrow funding.
- Compare remaining credit capacity for a temporary buydown or permanent discount points.
- Remove any unused credit that cannot legally or contractually benefit the buyer.
Seller-contribution ceilings vary by loan type, occupancy, and down payment. A larger negotiated credit does not override those limits.
Distinguish concessions from seller obligations
South Dakota's statutory seller-paid Real Estate Transfer Fee is $0.50 per $500, equivalent to 0.10%. Seller property-tax prorations address ownership periods rather than serving as interchangeable buydown money. The lender determines how each item is classified under the applicable program.
Review the arrears tax-credit guide alongside your proposed concession. Finally, budget for the year-three payment without assuming a refinance: future rates, property values, and qualification may not support one.

Editorial Methodology & Primary Sources
Verification date: Not recorded; check the primary source and lender timestamp before relying on an estimate.
Rate comparisons use participating lender feeds, not a whole-market survey or guaranteed offers. Freddie Mac PMMS is a market benchmark, not a personalized quote. Calculator models rely on published regulatory formulas and disclosed assumptions rather than fabricated first-person loan testing.
Monthly principal and interest use the amortization formula P × r / (1 − (1 + r)−n), where r is the monthly note rate and n is the number of payments; at zero interest use P / n. PITI adds monthly property taxes and homeowners insurance; PMI is separate. APR includes applicable finance charges under Regulation Z and is not the note rate used for payments.
