What Is a Conventional Loan?

A conventional loan is a mortgage that is not insured or guaranteed by a government agency such as the FHA, VA, or USDA. Lenders underwrite these loans based on private guidelines, most commonly those set by Fannie Fannie Mae. Because they are not government‑backed, the borrower’s credit profile and financial stability play a larger role in approval.

Down Payment & Credit Requirements

First‑time buyers can often qualify with as little as a 3% down payment, though many lenders prefer a larger cushion. A credit score of about 620 or higher is typically the minimum for conventional financing, and higher scores can secure better interest rates and lower costs.

Private Mortgage Insurance (PMI)

If the down payment is below 20% of the purchase price, lenders usually require private mortgage insurance. PMI protects the lender if the borrower defaults. Once the loan balance falls below 80% of the home’s original value, the borrower can request cancellation of PMI.

Debt‑to‑Income (DTI) Ratio

Lenders look at the borrower’s total monthly debt payments—including the projected mortgage payment—relative to gross monthly income. A DTI of 45% or lower is commonly the upper limit for conventional loans, though some programs may allow higher ratios with compensating factors.

Loan Limits

Conventional loan amounts are capped by the Federal Housing Finance Agency (FHFA) each year. In most parts of South Dakota, the standard limit applies, which is sufficient for many single‑family homes. In higher‑cost areas, the limit may be slightly higher.

Closing Process in South Dakota

• Most closings are handled by a title company rather than an attorney, though some counties may still use attorneys.
• Because South Dakota has no state income tax, there is no state‑level income‑tax withholding on mortgage interest, simplifying the tax deduction calculation.
• Buyers should budget for typical closing costs such as title insurance, recording fees, and prepaid items, which together usually range from 2% to 5% of the loan amount.

State‑Specific Considerations

South Dakota’s lack of a state income tax can improve a borrower’s net cash flow, potentially allowing a larger mortgage payment than in states with income tax. Additionally, the state participates in the South Dakota Housing Development Authority’s first‑time‑buyer programs, which may offer down‑payment assistance or favorable loan terms for qualifying households.
