This calculator starts with South Dakota’s statewide averages: property tax of 1.02% of the price per year and homeowners insurance of $3,740 per year. They are estimates — replace them with your local rate (or the home’s actual tax bill) and a real insurance quote for an exact payment.
Monthly payment on a typical South Dakota home
The median owner-occupied home in South Dakota is worth $289,600 (U.S. Census Bureau, 2024 ACS 1-year). Here is the full monthly payment on a $290,000 home with a 30-year fixed loan at 7.03%, the Freddie Mac 30-year average for the week ending September 24, 2026, with 20% down and with 5% down:
| Monthly cost | 20% down | 5% down |
|---|---|---|
| Home price | $290,000 | $290,000 |
| Down payment | $58,000 | $14,500 |
| Loan amount | $232,000 | $275,500 |
| Principal & interest | $1,548.18 | $1,838.46 |
| Property tax (1.02% a year) | $246.50 | $246.50 |
| Homeowners insurance | $311.67 | $311.67 |
| PMI (0.5% of the loan a year) | $0.00 | $114.79 |
| Total monthly payment | $2,106.35 | $2,511.42 |
| Total interest over 30 years | $325,344 | $386,346 |
Putting 5% down instead of 20% raises the payment by $405 a month: $290 more in principal and interest on the bigger loan plus $115 for private mortgage insurance. PMI drops off automatically after about 11 years 10 months, when the balance is scheduled to reach 78% of the home’s original value (if your payments are current). Property tax and insurance make up 26% of the 20%-down payment.

What drives housing costs in South Dakota
On the $290,000 example home, homeowners insurance is the larger add-on to the loan payment in South Dakota: $312 a month versus $247 for property tax (about 1.3 times as much). South Dakota’s median home value of $289,600 is 15% below the middle state’s $341,900, and each extra $50,000 of price adds about $309 to the monthly payment with 20% down at 7.03%.
- Local property tax rates. Property taxes are levied mainly by local governments — such as counties, cities, school districts and special districts — so bills in South Dakota can sit well above or below the 1.02% statewide average. Your local assessor or tax collector can tell you the rates that apply to a specific address.
- Exemptions and assessment limits. Many states offer homestead exemptions or credits for owner-occupied homes, and some limit how fast a home’s assessed value can rise. Where limits reset when a home sells, a new buyer usually pays a higher effective rate than the statewide figure, which averages long-time owners and recent buyers.
- Insurance risk and coverage. Premiums depend on the cost to rebuild, local weather and wildfire risk, the roof’s age, your deductible and claims history. Most homeowners policies do not cover flood damage; flood insurance is a separate policy.
- Down payment and PMI. With less than 20% down on a conventional loan, PMI adds to the payment until it is canceled: automatically when the balance is scheduled to reach 78% of the original value, or earlier at your request at 80%.
- HOA dues and extra costs. Condos and many newer subdivisions charge HOA dues. Add them in the calculator’s “Taxes, insurance, PMI & HOA” section to see your true monthly cost.

Frequently asked questions
What is the mortgage payment on a median-priced home in South Dakota?
About $2,106 a month. That assumes a $290,000 home (near South Dakota’s $289,600 median value), 20% down and a 30-year fixed loan at 7.03%: $1,548 in principal and interest, $247 in property tax and $312 in homeowners insurance. With 5% down, the payment rises to about $2,511 because the loan is larger and PMI is added.
What is the property tax rate in South Dakota?
The statewide effective rate is about 1.02% of home value: the median homeowner paid $2,940 in real estate taxes on a median home worth $289,600 (U.S. Census Bureau, 2024 ACS 1-year). That is the 18th-highest rate among the 50 states and D.C. The Tax Foundation’s aggregate method gives 1.00%. Your own bill depends on where the home is, how it is assessed and any exemptions you qualify for.
How much is homeowners insurance in South Dakota?
Two 2026 rate surveys put the average at $3,740 (Insurance.com) and $2,724 (Insurify) a year for a policy with $300,000 of dwelling coverage, or roughly $312 a month. The two estimates differ by 31%, a sign that premiums vary widely. Your premium depends on the rebuild cost, location, roof age, deductible and claims history, so compare quotes before you buy.
How much are property taxes on a $400,000 home in South Dakota?
About $4,080 a year, or $340 a month, at South Dakota’s 1.02% statewide effective rate. At the middle state’s rate of 0.75%, the same home would owe $3,000. Actual bills vary with local rates, assessments and exemptions, and in states that cap assessment increases a sale can reset the assessment to market value, so check the home’s current tax bill before you buy.
Is South Dakota more expensive for homeowners than neighboring states?
For the same $400,000 home, South Dakota has the 3rd-highest monthly payment of the 7 (itself and its 6 neighbors): $2,787 with 20% down at 7.03%. Its neighbors range from $2,498 in Wyoming to $3,068 in Nebraska. The loan payment is identical, so the differences come entirely from property tax and insurance, before any difference in home prices.
How long will I pay PMI with 5% down in South Dakota?
On a $290,000 home with 5% down, PMI at 0.5% of the loan a year adds about $115 a month. Under the federal Homeowners Protection Act, if you are current on payments, the servicer must cancel PMI automatically when the balance is scheduled to reach 78% of the home’s original value — about 11 years 10 months into the loan at 7.03%. You can ask to cancel it earlier, at 80%, if you have a good payment history.
