First-time buyers in Sioux Falls can tap South Dakota Housing (SDHDA) programs that offer down payment assistance of 3% or 5% of the loan amount, a Mortgage Credit Certificate that turns part of your mortgage interest into a dollar-for-dollar federal tax credit, and competitive fixed-rate loans. You generally qualify if you haven’t owned a home in the past three years, your income is within local limits, and the purchase price is at or below $410,000. The assistance comes as a no-monthly-payment second loan, and you apply through an SDHDA-participating lender — not the state directly.

If you’re trying to buy your first home in Sioux Falls, the down payment is usually the wall — not the monthly payment. The good news: South Dakota has real programs built to get you over that wall, and a lot of buyers I work with don’t realize they qualify until we run the numbers. Here’s how the help actually works.
Most of these programs run through South Dakota Housing (SDHDA), the state housing authority. You don’t apply with the state, though — you apply through an approved local lender who offers SDHDA loans, and they walk you through eligibility. That’s an important detail, because the “only way to know for sure” is to apply with a participating lender.
Who counts as a first-time buyer
The definition is more forgiving than it sounds. For SDHDA, a first-time buyer is simply someone who hasn’t owned a home in the past three years. So if you owned years ago and have been renting since, you may qualify all over again. A couple of useful wrinkles:
- Previously owning a mobile home that wasn’t permanently attached to a foundation generally doesn’t disqualify you.
- Veterans may qualify through a waiver even if they don’t meet the first-time rule — worth asking your lender about directly.
Beyond the three-year rule, you’ll need your household income to fall at or below the local SDHDA income limits, and the home’s purchase price to be at or below $410,000 — a ceiling that covers a large share of Sioux Falls listings. Income limits vary by county and household size and change periodically, so those are the numbers to confirm with a lender for Minnehaha or Lincoln County before you count on them.
The down payment assistance — how it actually works
This is the piece that moves the needle for most first-time buyers.
SDHDA’s Down Payment Assistance (DPA) gives you either 3% or 5% of your loan amount to put toward your down payment and closing costs. The way it’s structured matters:
- It’s a “silent” second mortgage — 0% interest, no monthly payment.
- You don’t pay it back month to month. It’s repaid only when you sell or refinance the home.
- The trade-off: taking DPA bumps your rate on the main mortgage slightly — about 1% higher for the 3% option and 1.125% higher for the 5% option.
That trade-off is the whole decision. If the thing standing between you and a home is cash at closing, paying a bit more on the rate to get in now — and refinancing later if rates drop — often makes sense. If you already have enough for the down payment, you might skip DPA and take the lower rate. There’s no universally right answer; it depends on your cash on hand and how long you plan to stay.
The tax credit most buyers miss
SDHDA also offers a Mortgage Credit Certificate (MCC). This one is easy to overlook because it’s not cash up front — it’s a dollar-for-dollar reduction in your federal income tax based on a percentage of the mortgage interest you pay each year. In plain terms, it can put money back in your pocket every tax season for as long as you have the loan, which improves what you can comfortably afford. Your lender can tell you whether pairing an MCC with your loan makes sense for your situation.
There’s also the state’s Governor’s House program, which provides affordably priced, modest homes to income-qualified buyers — a narrower option, but worth knowing exists.
What this looks like in Sioux Falls right now
Timing matters, and the current market is actually favorable for using these programs. The Sioux Falls metro median sits around $330,000 — comfortably under the $410,000 price cap — and homes are selling in roughly 75 days, so you have a bit more breathing room than during the frenzied years. New construction is also competing hard on affordability right now, which widens the pool of homes a first-time buyer can realistically target.
A realistic first-time path in Sioux Falls often looks like this:
- Get pre-approved with an SDHDA-participating lender first — this tells you your price range and whether you qualify for DPA and the MCC.
- Decide on assistance: compare your monthly payment and cash-to-close with DPA versus without it.
- Shop within your real budget — including the surrounding communities like Harrisburg, Tea, Brandon, and Hartford, where first-time-friendly inventory often shows up.
- Write a competitive but protected offer with your agent, keeping your inspection and financing contingencies in place.

One honest note: these programs have real paperwork and specific rules, and the income and price limits get updated. Everything here is a starting point — your lender confirms the current figures and what you actually qualify for. That’s exactly the kind of thing I help my first-time buyers line up before we start touring homes, so you’re shopping with a real budget instead of a guess.
Frequently asked questions
Do I need 20% down to buy my first home in Sioux Falls?
No. That’s the most common myth I hear. Many first-time buyers use loans that require far less down, and SDHDA’s down payment assistance can cover 3% or 5% of the loan as a no-monthly-payment second. What you actually need depends on your loan type and whether you use assistance — a lender can pin down your real number.
How much is SDHDA down payment assistance?
It’s 3% or 5% of your loan amount, provided as a 0% silent second mortgage with no monthly payment, repaid only when you sell or refinance. Taking it raises your primary mortgage rate slightly (about 1% for the 3% option, 1.125% for the 5% option), so it’s a cash-now versus rate trade-off worth running both ways.
What’s the income limit for first-time buyer programs in South Dakota?
SDHDA sets income limits by county and household size, and they change periodically, so there’s no single number. For a Sioux Falls purchase, confirm the current Minnehaha or Lincoln County limit with an SDHDA-participating lender. The home’s purchase price also has to be at or below $410,000.
Can I use these programs if I owned a home before?
Possibly. SDHDA’s first-time definition means you just can’t have owned a home in the past three years — so prior owners who’ve been renting may qualify again. Veterans may also qualify through a waiver even without meeting the first-time rule.
Where do I apply?
Not with the state directly — you apply through an SDHDA-participating lender, who handles the application, verifies your eligibility, and pairs the assistance or tax credit with your loan. Getting pre-approved with one is the right first step.
