How much house can I afford in South Dakota?
The median home in South Dakota costs roughly $295,000. With a 10% down payment at a 6.85% mortgage rate, the all-in monthly payment is about $2,442 — which means you'd typically need an annual income near $104,638 to keep housing under the standard 28% front-end ratio.

What the South Dakota numbers actually mean
At today's mortgage rates, the headline payment isn't the only number that matters in South Dakota. Property tax adds roughly $305/month at the median home price — a rate of 1.24%, which is near the national average — neither a tailwind nor a major drag on monthly cost.
The required income ($104,638) is roughly $35,638 higher than the South Dakota median household income ($69,000). That gap is why affordability feels tight even for households earning around the state median — the median home was priced for buyers earning above-median incomes when rates were lower.
The 28% / 36% rule, briefly
Lenders typically want your housing payment (PITI) to stay under 28% of your gross monthly income, and your total debt payments (housing plus car loans, student loans, and minimum credit card payments) to stay under 36%. The first ratio is called the front-end DTI; the second is the back-end DTI.
The math above uses the front-end test. If you have meaningful other debt, you'll likely qualify for less than the income figure above suggests, because the back-end rule binds first. Use the full calculator to factor in your real other-debt monthly payments.
What changes the South Dakota number most
Three levers move your affordability in South Dakota dramatically more than the rest: your mortgage rate, your down payment, and PMI. A 1.0% lower mortgage rate on the median South Dakota home saves roughly $221/month. Crossing the 20% down threshold eliminates PMI, which on a low-down-payment loan costs another 0.5–1.5% of the loan amount per year.

Frequently asked questions
What income do I need to afford a $295k home in South Dakota?+
At a 6.85% rate with 10% down and 1.24% property tax, the all-in monthly payment is about $2,442. Using the standard 28% front-end rule, you'd need roughly $104,638 in annual gross income.
How does South Dakota's property tax compare?+
South Dakota's effective rate of 1.24% is near the national average — neither a tailwind nor a major drag on monthly cost.
Does this include HOA fees?+
No. HOAs vary too much to assume a default. If your target home is in an HOA, add the monthly fee directly to the payment above — it doesn't change the loan math, but it raises your DTI and effectively reduces what you can afford on a given income.
What credit score do I need to qualify?+
Conventional loans typically require a 620+ credit score; FHA loans go down to 580 with 3.5% down (or 500 with 10% down). A higher score lowers your rate, which compounds into thousands of dollars over the loan.
