The minimum credit score to buy a house in Sioux Falls is generally 620 for a conventional loan and 580 for an FHA loan with 3.5% down, while USDA loans usually want 640 and VA loans set no federal minimum. But getting approved is only half the story: the higher your score, the lower your interest rate and mortgage insurance — which can save you tens of thousands of dollars over the life of the loan.
Quick Answer: Most Sioux Falls buyers need a credit score of at least 620 for a conventional mortgage, 580 for an FHA loan (3.5% down), or 640 for a USDA loan. VA loans have no federal minimum, though most lenders look for 580–620. Scores of 740 and above unlock the best rates. The good news for local buyers: South Dakota’s average credit score (731) already clears most of these thresholds.
Minimum credit score by loan type in Sioux Falls
There isn’t one magic number — the minimum depends on the loan you choose. Here’s where most Sioux Falls lenders set the bar in 2026:
| Loan type | Typical minimum score | Minimum down payment |
|---|---|---|
| Conventional | 620 | 3% |
| FHA | 580 (3.5% down) · 500–579 (10% down) | 3.5% |
| VA (veterans / active duty) | No federal minimum; lenders usually 580–620 | 0% |
| USDA (eligible rural areas) | 640 | 0% |
| Jumbo | 700+ | 10%+ |
Keep in mind these are lender minimums. A score that barely clears the line will still qualify you, but you’ll usually pay a higher rate and more mortgage insurance than a buyer with a 740. Many parts of the Sioux Falls metro — including Harrisburg, Brandon, Tea, and the rural edges of Minnehaha and Lincoln counties — can also qualify for zero-down USDA financing, which makes that 640 benchmark worth aiming for.
What’s the average credit score in South Dakota?
South Dakotans tend to have strong credit. The average FICO score in South Dakota is about 731, well above the national average of 714 (Experian data, 2026). That puts the typical local buyer squarely in FICO’s “good” range (670–739) and comfortably past the 620 conventional threshold.
Here’s how the FICO ranges break down:
- 800–850: Exceptional — the best rates available
- 740–799: Very good — still top-tier pricing
- 670–739: Good — qualifies for most loans
- 580–669: Fair — FHA territory, higher costs
- 300–579: Poor — limited options; focus on rebuilding first
How your credit score affects your rate (and your monthly payment)
This is the part most buyers underestimate. Two people can buy the same Sioux Falls house on the same day and walk away with very different payments — because of their credit scores.
As of the week of November 5, 2026, Freddie Mac put the average 30-year fixed rate at 7.18%. But that’s an average. A buyer with a 760 score might land below it, while a buyer in the low 600s could pay half a percent more or higher. On a $279,000 loan (roughly a median-priced $310,000 Sioux Falls home with 10% down), a 0.5% difference in rate is about $95 more a month — nearly $34,000 over a 30-year loan. A stronger score also means lower private mortgage insurance if you’re putting down less than 20%.
In other words, spending a few months raising your score before you shop can be one of the highest-paying moves you make as a buyer.
Credit scores and down payment help in South Dakota
If you’re a first-time buyer, South Dakota Housing offers down payment assistance — including the new “Give Me Five” program (launched November 2026), which provides 5% of your loan amount toward your down payment on homes priced up to $410,000. These programs run through participating lenders and set their own credit requirements, typically in the low-to-mid 600s. If your score is close, it’s worth a conversation before you rule yourself out.
How to raise your credit score before you buy
If you’re not where you want to be yet, a few focused months can make a real difference:
- Pay every bill on time. Payment history is the single biggest factor in your score.
- Lower your credit utilization. Try to keep balances under 30% — ideally under 10% — of your limits.
- Don’t close old accounts. Length of credit history helps you; keep long-standing cards open.
- Avoid new debt before closing. Hold off on financing a car or furniture until after you have your keys.
- Check your report for errors. You can pull all three bureaus free at AnnualCreditReport.com and dispute any mistakes.
What if your score isn’t there yet?
Not quite at 620? You still have options. An FHA loan can work with a 580, a creditworthy co-borrower can strengthen your application, and a short, deliberate rebuild often gets buyers across the line faster than they expect. The worst move is guessing. We can connect you with a trusted local lender who will pull your credit, tell you exactly where you stand, and map out the shortest path to a “yes.”
Frequently asked questions
Can you buy a house in Sioux Falls with a 600 credit score?
Yes — a 600 score is above FHA’s 580 minimum, so an FHA loan with 3.5% down is usually on the table. You likely won’t qualify for a conventional loan (620+) yet, and you’ll pay a higher rate, so it’s often worth nudging your score up first.
What credit score do first-time buyers in Sioux Falls usually have?
Most first-time buyers who qualify fall somewhere in the 640–720 range. With South Dakota’s average score at 731, plenty of local first-timers are already in strong shape.
Does checking my own credit score hurt it?
No. Checking your own score is a “soft inquiry” and never affects it. Only a lender’s “hard inquiry” when you formally apply can ding it slightly — and even then, rate-shopping within a short window counts as a single inquiry.
How long does it take to raise my credit score?
It depends on what’s holding it down, but many buyers see meaningful gains in three to six months by paying down balances and making every payment on time.
Do I need a perfect 800 score to get a good rate?
No. Lenders generally reserve their best pricing for scores of 740 and up, so anything in that range puts you in top-tier territory — no perfection required.
