What Credit Score Do You Need to Buy a House in Sioux Falls, SD?

There is no single credit score that unlocks a home in Sioux Falls, but there are clear, practical thresholds to aim for. In 2026, conventional loans generally start at 620, FHA accepts 580 with 3.5 percent down, and South Dakota Housing's first-time buyer programs require a 620. Here is exactly what each loan type expects, what your score means for your rate and your payment, and how to move your number before you apply.

The short answer, by loan type

The most useful way to think about your credit score is loan by loan, because each program sets its own floor. These are the minimums buyers in Sioux Falls are working with right now:

• Conventional loans: generally a 620 minimum from Fannie Mae and Freddie Mac. This is the most common loan type in South Dakota, and at 620 it is possible to buy with as little as 3 percent down through low-down-payment programs, with private mortgage insurance until you build equity.
• FHA loans: 580 with a 3.5 percent down payment, or 500 with a 10 percent down payment. Scores below 500 are not eligible. FHA's low-down-payment, lower-score path is the most common route for first-time buyers, which is why I walk so many clients through it.
• VA loans: the VA sets no minimum score, but most lenders overlay their own requirement of roughly 580 to 620, with 620 common. VA loans also allow zero down payment for eligible veterans and service members.
• USDA loans: the USDA sets no score minimum either, and most lenders look for around 640. These are zero-down loans for homes in qualifying rural areas, which covers parts of the Sioux Falls region outside the main metro.
• South Dakota Housing (SDHDA): a minimum of 620 to qualify for its first-time buyer programs, which can layer 3 percent or 5 percent of your loan at 0 percent interest toward down payment and closing costs. I cover every program in the South Dakota down payment assistance guide.

One pattern worth noticing: almost every door opens at 620. If you are in the 620 to 660 range, you are not on the bench, you are in the game. The tradeoff is rate and monthly payment, which is where improving your score pays off in dollars, not just approval.

Where Sioux Falls buyers stand right now

Interest rates matter as much as your score, because together they set your payment. The 30-year fixed-rate mortgage averaged 6.95 percent the week of September 17, 2026, according to Freddie Mac's Primary Mortgage Market Survey, up from 6.26 percent a year earlier. Rates have been swinging in the mid to high 6s all fall, which is why the timing conversation deserves its own article on buying now versus waiting.

On the price side, the median sale price in Sioux Falls has run around $327,000 in recent readings, with different sources landing anywhere from the mid-$310,000s to the mid-$340,000s depending on the month and the metric. Here is what the rate does to those numbers: a $300,000 loan at 6.95 percent for 30 years carries roughly $1,985 a month in principal and interest, before taxes, insurance, and HOA dues. Every quarter point you can shave off the rate, whether through a stronger score or shopping lenders, moves your payment in the right direction.

The practical takeaway: a buyer with a 640 and a buyer with a 760 can both buy in Sioux Falls. They will simply be quoted different rates, and that difference is real money over 30 years.

Your score is only part of the loan picture

It helps to know what the lender is actually grading, because credit score is one of four big boxes. The others are your debt-to-income ratio, your down payment, and your employment and income history.

Debt-to-income ratio. Most lenders want your total monthly debt payments, including the new mortgage, at or below roughly 43 percent of your gross monthly income. This is why two people with the same score can get different answers: the one carrying more monthly debt may not qualify for the same loan amount. Paying down a car loan or credit card before you apply helps both your score and this ratio.

Down payment. Your down payment sets your loan-to-value ratio, and the more you put down, the less risk the lender carries. At 20 percent you avoid private mortgage insurance, but you do not need 20 percent to buy, and I have had many clients start with 3 to 5 percent down and build from there.

Employment history. Lenders want two years of stable employment or income, which for most buyers means pay stubs, W-2s, and tax returns. New job in the same field is usually fine; a long gap needs a conversation.

Treat your credit score as one tool in the kit rather than the whole verdict. I have seen buyers with great scores but heavy debt get less favorable terms than buyers with decent scores and clean debt profiles.

Which credit score does the lender actually use?

The number you see in a banking app is usually your VantageScore or a general FICO score, but mortgage lenders pull your mortgage-specific FICO scores from each of the three bureaus, and they use the middle of those three as your qualifying score. That means the score on your credit card app can differ from the number on your Loan Estimate, sometimes by 20 to 40 points.

You are entitled to free copies of your credit reports from each of the three bureaus every 12 months at annualcreditreport.com, the officially authorized free source created by federal law. Checking those reports and your own score is a soft inquiry, which never hurts your score. When a lender runs your credit for a mortgage, that is a hard inquiry, and the good news is that mortgage rate shopping within a focused window, generally around 45 days, is counted as a single inquiry by the scoring models. So comparison shopping for lenders will not wreck your score; it is exactly what I encourage.

How to raise your score before you apply

Give yourself two to three months of runway, because credit scores respond to recent behavior faster than people expect. The moves that work, in order of impact:

• Pay down credit card balances. High utilization, the share of your available credit you are using, drags scores down more than almost anything else. Getting balances under 30 percent of your limits, and ideally well below that, is the single fastest score move for most people.
• Check your reports for errors. A surprising share of credit reports contain mistakes, and a disputed error can be corrected in weeks. Pull all three reports and read them line by line.
• Make every payment on time. Payment history is the biggest component of your score, and even one late payment can cost you more than a whole card payoff might gain. Set up autopay on everything.
• Keep old accounts open. Closing a card can shorten your credit history and raise your utilization at the same time. Unless it carries an annual fee you hate, let it sit.
• Do not open new credit before closing. No new cards for the furniture and no financing for the car in the weeks before you close. New inquiries and new debt right before closing are how otherwise-approved loans fall apart, and a lender can even re-run your credit the day before.

If your score is under 620, you still have a path: FHA at 580 with 3.5 percent down is the most common on-ramp, and it is often the right answer rather than waiting a year to push a score higher. What I tell clients is simple: run the numbers both ways. If six months of deliberate credit work could drop your rate by half a point, the payoff is often worth the wait. If you need to move this season, FHA gets you there now.

Get the number from a lender, not from the internet

The honest truth about credit score articles, including this one: the floors are accurate, but your approval is decided by a lender looking at your complete file. The fastest way to know where you stand is a pre-approval, where a lender pulls your credit, verifies your income, and tells you exactly what you qualify for, your rate, your down payment options, and your estimated payment. It takes a day or two, it costs nothing until you commit, and it turns the whole conversation from hypothetical to real.

When clients come to me, we start with a lender conversation before we ever look at houses. You should know your number, your budget, and your likely payment before you tour a single home, because falling in love with a house you cannot qualify for is the most avoidable heartbreak in real estate. And when we do find your home, my builder's eye handles the condition side: roof, electrical, foundation, water, the things a credit score will never tell you about. The whole picture, credit and condition together, is how confident purchases get made.

If you are not sure what your score will get you in this market, that is a fifteen-minute phone call, not a research project.
