Frequently Asked Questions
Personal Loans in South Dakota: FAQ
Personal loan credit requirements in South Dakota are set nationally by each lender — there are no state-specific minimums. LightStream typically approves borrowers with FICO scores of 670 and above.
Marcus and Discover approve from around 660. Upstart accepts scores as low as 300 through their AI underwriting model, though lower scores mean higher APRs and origination fees.
Check your score free through your bank or credit card issuer before applying.
Loan limits vary by lender: LightStream lends up to $100,000; Marcus and Discover up to $40,000; Upstart up to $50,000. The amount you are approved for depends on your income, debt-to-income ratio, and credit history — not your state of residence.
For South Dakota borrowers averaging $12,400 in loan balances, most major lenders offer sufficient capacity.
South Dakota follows federal lending regulations enforced by the CFPB, which means standard rules on truth-in-lending disclosures, prepayment penalties, and fee disclosures apply. All four lenders on this list are federally chartered or bank-partnered institutions, so South Dakota state-level rate caps do not restrict what they can charge.
Always review your loan agreement for the full APR and any fees before signing.
Funding timelines do not vary by state. LightStream offers same-day funding on applications approved before 2:30 PM ET on business days.
Marcus and Discover fund within 1 to 5 business days. Upstart often funds within 1 business day for straightforward applications.
Direct deposit to your South Dakota bank account is the standard delivery method for all four lenders.
