You’ve saved for the down payment. You found the house. Then your lender hands you a number for “closing costs,” and it’s thousands of dollars you weren’t planning on.

This catches Sioux Falls buyers off guard all the time. So let’s put real numbers on it, break down every line, and talk about how you actually shrink the check you write at closing.

The short answer, in dollars

Plan on 2% to 5% of the purchase price. The average buyer in South Dakota pays about 3.73%.

Here’s what that looks like across the price points you’re likely shopping in the Sioux Falls metro:

  • $300,000 home — about $6,000 to $15,000, with most buyers near $11,000
  • $335,000 home (the June 2026 median) — about $6,700 to $16,750, with most near $12,000
  • $385,000 new build (the new-construction median) — about $7,700 to $19,250

That’s a wide range because your loan type, your lender, your insurance, and the time of month you close all move the number. But the middle of that range — right around 3% to 3.7% — is where most Sioux Falls buyers actually land.

And to be clear: this is separate from your down payment. If you’re putting 5% down on a $335,000 home, that’s about $16,750 for the down payment plus roughly $10,000 to $12,000 in closing costs. Knowing both numbers up front is the difference between a smooth closing and a scramble the week before.

What’s actually in your closing costs

Your closing costs aren’t one fee. They’re a stack of them, and they fall into three buckets: lender fees, third-party services, and prepaids.

Lender fees. This is the origination side — loan origination, underwriting, and processing. Together they often run 0.5% to 1% of your loan amount, so figure $1,500 to $3,000 on a typical Sioux Falls mortgage. Ask your lender for a Loan Estimate and read this section closely, because it’s the part that varies most from lender to lender.

Third-party services. These pay the people who verify the home is worth the price and clean to buy. Your appraisal runs $350 to $600 in Sioux Falls — more if you’re buying acreage out toward Canistota or Madison, where the appraiser has more ground to cover. Your home inspection is $300 to $500, and if you add a radon test — smart in Minnehaha and Lincoln counties, which sit in EPA Radon Zone 1 — that’s another $150 to $250. Then there’s the title work: the title company runs your closing here in South Dakota (we don’t use escrow companies the way coastal states do), and you’ll pay closing fees plus a lender’s title insurance policy, usually a few hundred dollars. Owner’s title insurance is commonly picked up by the seller in this market.

Prepaids and escrow reserves. This is the bucket that surprises people, because it’s not really a “fee” — it’s money for costs you’d owe anyway, just collected early. It includes your first year of homeowners insurance (often $1,500 to $2,500), prepaid interest from your closing date to the end of the month, and a few months of property taxes and insurance set aside in your escrow account so your lender can pay those bills when they come due. Buy on the 3rd of the month and you’ll prepay almost a full month of interest. Buy on the 28th and you’ll prepay just a few days. Small timing choice, real dollars.

One line you won’t see on the buyer side: the South Dakota transfer fee. That’s the $0.50 per $500 of value under SDCL 43-4-21, and in this state the seller pays it. It’s one of the reasons buying here costs less at the table than in a lot of the country.

Your real target number is “cash to close” — and you have levers

Closing costs are only part of the check. The number that matters is your cash to close, and it works like this:

Down payment, plus closing costs and prepaids, minus your earnest money, minus any seller concessions. Your earnest money deposit — usually around 1% of the price in Sioux Falls — isn’t an extra cost. It’s a credit that comes back to you at closing and counts toward this total.

Now the part most buyers don’t push on: several of these costs are negotiable or coverable.

Seller concessions. You can ask the seller to pay part of your closing costs — written right into your offer. How well that lands depends on the listing. Sioux Falls is still a seller’s market in 2026, with inventory down around 30% and about a 3.3-month supply, so on a fresh, well-priced home in Harrisburg or Tea you’re not likely to win a big concession. But on a listing that’s been sitting, or on standing builder inventory the builder wants moved before quarter’s end, asking for $5,000 toward your costs is a reasonable play. Just know your loan type caps how much the seller can contribute.

Lender credits. Your lender can cover some closing costs in exchange for a slightly higher interest rate. That trade can make sense if you’re tight on cash now and plan to refinance or move within a few years — but run the math, because over a long hold you pay it back in interest.

Down payment assistance. If you qualify, South Dakota Housing programs can cover a chunk of your down payment and, in some cases, help with costs. I walk through those in detail in down payment help for Sioux Falls first-time buyers.

New construction. Builders like Allen Homes, Van Buskirk, and Cordes often cover part of your closing costs if you use their preferred lender. That incentive is real money — sometimes several thousand dollars — but compare the preferred lender’s rate and fees against an outside quote before you commit, because a rate that’s a quarter-point higher can quietly erase the savings.

You can also shop the pieces you control. Inspection and title costs vary by provider, and a good buyer’s agent — which is what I do for a living — helps you order this stack so nothing is a surprise on closing day.

Frequently asked questions

Do buyers pay the transfer fee in South Dakota?
No. South Dakota’s transfer fee (SDCL 43-4-21, $0.50 per $500 of value) is paid by the seller, not the buyer. On a $335,000 home that’s a $335 cost the seller carries, not you.

Can I roll closing costs into my mortgage?
Usually not directly on a conventional purchase — closing costs are paid at the table, not financed into the loan. But you can effectively cover them three ways: seller concessions written into your offer, lender credits in exchange for a higher rate, or down payment assistance if you qualify. Some VA and USDA loans have their own rules that allow more flexibility, so ask your lender.

How much total cash do I need to buy a $335,000 home in Sioux Falls?
Budget your down payment plus roughly $10,000 to $12,000 in closing costs and prepaids. At 5% down that’s about $16,750 plus $11,000, so somewhere near $27,000 to $28,000 before any seller concessions or assistance bring it down. Your earnest money is part of that total, not extra.

When do I find out my exact closing costs?
Your lender must send a Loan Estimate within three business days of your application — that’s your early read. Then you’ll get a Closing Disclosure at least three business days before closing with the final, locked figures. Compare the two line by line, and call your lender or agent about anything that jumped.

Are closing costs cheaper on new construction in Tea or Harrisburg?
Not inherently — but many builders offset them. If you use the builder’s preferred lender, they’ll often cover part of your closing costs as an incentive. Weigh that against the preferred lender’s rate before deciding, and remember new-construction appraisals in a fast-rising corridor can come in low. Here’s what to do if your Sioux Falls appraisal comes in low.

Let’s map your number before you write an offer

The buyers who close without stress are the ones who knew their cash-to-close number weeks ahead — not the ones who found out three days before. If you’re getting ready to buy in Sioux Falls, Harrisburg, Tea, Brandon, or the surrounding communities, let’s sit down and put real numbers on your specific price range and loan type.
