How to choose a lender in South Dakota
The lender that writes the most loans isn't automatically the one that will quote you the lowest rate. Your rate depends on your credit, down payment and loan type — not a lender's market share. The reliable way to find the best deal is to get a Loan Estimate from three or more of these lenders in the same two-week window (it counts as a single credit inquiry) and compare the APRs.
Weigh national lenders and online brokers, which often lead on price, against South Dakota banks and credit unions, which may offer relationship pricing and access to SDHDA programs. Start with the local benchmark and assistance below.
