South Dakota 66-County 2026 Conforming ($832,750) and FHA ($541,287) Loan Limits — Prairietally
Updated October 2026
For 2026, South Dakota's baseline conforming mortgage limit is $832,750 across all 66 counties. The statewide FHA single-unit floor is $541,287. Whether you are buying in Minnehaha, Pennington, Brown, Brookings, or a rural county, start with the correct loan category and property unit count before deciding how much financing is available.
Read the limits as financing thresholds
| Mortgage category | 2026 single-unit reference | Practical meaning |
|---|---|---|
| Baseline conforming | $832,750 throughout South Dakota | Maximum baseline loan amount eligible for conforming treatment |
| FHA | $541,287 statewide floor | Compare the FHA base mortgage with the applicable county limit |
| Jumbo | Generally above the conforming threshold | Lender-specific underwriting and pricing apply |
Verify the applicable year and unit count through FHFA Loan Limits and HUD FHA Mortgage Limits. Two- to four-unit properties have different limits; do not use a single-unit figure for a duplex simply because you intend to occupy one unit.
A loan limit is not an approval amount. Income, existing debts, credit, available funds, appraisal results, and lender requirements still determine what a borrower can qualify to finance.
Separate purchase price from mortgage amount
A $900,000 home does not automatically require jumbo financing. With a $100,000 down payment, the proposed $800,000 mortgage is below the 2026 baseline conforming limit, before considering any financed amounts or other transaction details.
Conversely, a smaller down payment on the same home could push the required loan above $832,750. Compare the resulting cash requirement, rate, reserves, and mortgage insurance rather than choosing solely by the label.
FHA comparisons require particular care because upfront mortgage insurance may be financed. Ask the lender to distinguish the base mortgage used for the limit test from the total balance after permitted financed insurance. The mortgage options guide explains the broader differences among financing types.
Apply local costs before setting a budget
Program limits and assistance eligibility are separate tests. South Dakota Housing income and purchase-price restrictions do not automatically rise to match federal loan limits. Verify both when combining a mortgage with state assistance.
Use the monthly payment calculator to add insurance, property taxes, and mortgage insurance to principal and interest. South Dakota has no state personal income tax, but an owner-occupied classification application and realistic escrow estimate still matter. Leave room for maintenance and closing cash instead of treating the maximum available loan as your target.

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.
