What to know about getting a mortgage in South Dakota
South Dakota’s market is small and bank-heavy — the Sioux Falls financial sector gives the state more local lenders per capita than its size suggests. Hail exposure pushes insurance premiums well above the national average, and that line item moves the monthly payment more than typical lender-to-lender rate spreads.
The 2026 conforming loan limit in most South Dakota counties is $832,750 for a single-family home (designated high-cost counties go higher). Loans above that are jumbo — expect tighter underwriting and different pricing.
The credit-union rates are taken from each lender's public rate sheet on the effective date shown. We don't take affiliate fees, sell contributor data, or rank lenders by commission. The full methodology is on the methodology page.

Frequently asked: mortgages in South Dakota
Straight answers, grounded in the data on this page.
What is the best mortgage rate in South Dakota right now?+
The lowest conventional 30-year rate we're tracking in South Dakota this week that anyone can join is 7.000% from PenFed Credit Union, 0.40% below the U.S. average of 7.400%. It's a real posted rate, not a teaser — your actual rate depends on your credit, down payment, and loan type. Credit unions with restricted membership (military or employer-based) sometimes post lower; those are listed below with their eligibility.
How much do you need to put down for a house in South Dakota?+
The median home price in South Dakota is about $290,000, so 20% down is roughly $58,000. Many buyers put down far less: conventional loans go as low as 3%, FHA 3.5%, and VA/USDA can be 0% for those who qualify (with mortgage insurance when you put down under 20%).
Which credit unions can South Dakota residents join for a mortgage?+
South Dakota residents can currently get posted mortgage rates from Navy Federal Credit Union, PenFed Credit Union, Connexus Credit Union, and others. Many credit unions let anyone join through a small one-time association membership — each one's eligibility and exact join steps are on its page.
What first-time homebuyer programs does South Dakota have?+
South Dakota's housing finance agency is the South Dakota Housing. The First-Time Homebuyer program offers below-market rates with down-payment assistance up to 5% of the loan. These programs work through participating lenders, so you can (and should) still compare the program rate against the credit-union rates on this page.
What is the conforming loan limit in South Dakota?+
For most South Dakota counties the 2026 conforming loan limit is $832,750 for a single-family home (designated high-cost counties go higher). Loans above the limit are jumbo, which typically means tighter underwriting and different pricing.
Does RatePerch take referral fees from lenders in South Dakota?+
No. We don't take affiliate or referral fees, sell contributor data, or rank lenders by commission. Borrower-quoted rates are submitted anonymously by real South Dakota residents, and credit-union rates are copied straight from each lender's public rate sheet.
