To buy a median-priced home in Sioux Falls at today’s mortgage rates, you generally need to earn somewhere between $90,000 and $105,000 a year. Your exact number comes down to three things: your down payment, your existing monthly debts, and the interest rate you lock in.
Quick Answer: To comfortably afford Sioux Falls’s median-priced home — about $310,000 as of October 2026 — most buyers need a household income of roughly $90,000 to $105,000 per year, depending on down payment and existing debts. That keeps your total house payment near 28% of gross monthly income at today’s roughly 7.1% mortgage rate.
How lenders decide what you can afford
Most lenders size your loan around two guidelines. The first is the 28% rule: your total monthly house payment — principal, interest, property taxes, and insurance (often called PITI) — should land near 28% of your gross monthly income. The second is the 36% rule: all of your monthly debt, including the house payment plus car loans, student loans, and credit card minimums, should stay around 36% of gross income. These numbers can flex — FHA and other programs sometimes allow higher ratios — but they are the backbone of how a lender decides what you qualify for.
Work the math backward and the income question answers itself. If a median Sioux Falls home carries a monthly payment of roughly $2,100 to $2,450 (depending on your down payment at a 7.11% 30-year rate), the 28% rule points to a gross income of about $90,000 to $105,000 a year.
Income needed by home price in Sioux Falls
Here is a rough look at the household income it takes to stay near the 28% guideline across several price points. These estimates assume a 10% down payment, a 7.11% 30-year fixed rate (Freddie Mac, week of November 12, 2026), Minnehaha County property taxes near 1.16%, estimated homeowners insurance and private mortgage insurance, and no other monthly debt.
| Home price | Est. monthly payment (PITI) | Income needed (28% rule) |
|---|---|---|
| $250,000 | ~$1,975 | ~$85,000/yr |
| $310,000 (median) | ~$2,450 | ~$105,000/yr |
| $350,000 | ~$2,765 | ~$118,000/yr |
| $400,000 | ~$3,160 | ~$135,000/yr |
Put 20% down and the median-home number drops to roughly $91,000 a year, because you erase private mortgage insurance and shrink the loan. Carry a car payment or student loans and you’ll need a bit more. Treat these as planning estimates, not a pre-approval.
What moves your number up or down
Two buyers with the same salary can qualify for very different homes. These are the levers that matter most:
- Down payment. More money down means a smaller loan, a lower payment, and — once you hit 20% — no PMI. That can swing the income you need by $10,000 a year or more on a median home.
- Existing monthly debts. A $450 car payment or $300 in student loans eats into your 36% back-end room, so you’ll need more income to qualify for the same house.
- Your interest rate. Rate drives the payment. Sioux Falls buyers have caught a break lately — the 30-year fixed has fallen for four straight weeks to 7.11% as of mid-November 2026, its lowest in about seven weeks.
- Credit score. A stronger score earns a lower rate, which lowers the payment and the income you need. It also decides which loan programs are open to you.
- Loan type. VA and USDA loans allow $0 down for those who qualify; FHA opens the door with 3.5% down but adds mortgage insurance; conventional loans reward a bigger down payment.
Why South Dakota buyers stretch a paycheck further
A salary goes further here than in a lot of the country, and that is not just talk. South Dakota has no state income tax, so more of every paycheck lands in your bank account to put toward a mortgage. Pair that with a median price well below the national figure, and a Sioux Falls household often buys more home per dollar of income than a buyer earning the same salary in a high-tax metro.
First-time buyers have another lever. South Dakota’s “Give Me Five” program offers 5% of your first mortgage as down payment help that is forgiven after five years in the home, for eligible first-time buyers on homes priced up to $410,000. Less cash out of pocket up front can make a home you thought was out of reach suddenly fit your budget.
How to find your real number
The table above is a solid starting point, but the only figure that counts is the one a lender puts in writing. A pre-approval looks at your actual income, debts, credit, and down payment and tells you exactly what you can borrow — before you fall for a home that stretches you too thin. We work with local lenders every day and are happy to point you to one who will give you a straight answer.

Frequently asked questions
What salary do I need to buy a $300,000 house in Sioux Falls?
Figure on roughly $100,000 a year with 10% down and no other major debts, using the 28% guideline at a 7.11% rate. Put 20% down or carry no monthly debt and you can make it work on less; add a car or student-loan payment and you’ll need a little more.
Is the 28% rule a hard limit?
No. It’s a guideline lenders lean on, not a law. FHA and some other programs approve higher ratios, and buyers with strong credit, big down payments, or no other debt often qualify beyond 28%. It’s a smart ceiling for staying comfortable, but your pre-approval is the real answer.
Does South Dakota having no state income tax help me afford more?
Yes, indirectly. Because South Dakota doesn’t tax income, your take-home pay is larger than it would be on the same salary in a state that does. More net income means more room in your budget for a mortgage payment — one reason the same paycheck buys more house here.
Can I buy a home in Sioux Falls on a lower income?
Often, yes. A larger down payment, paying down debts before you apply, buying below the median, or using a $0-down VA or USDA loan or the Give Me Five down payment program can all lower the income you need. The best first step is a quick pre-approval conversation so you know your real range.
