Planning a purchase in South Dakota
The prefilled price, tax percentage, and interest rate are illustrative inputs, not verified South Dakota averages or lender quotes. Replace them with the property's price, a local tax estimate, an insurance quote, and your lender's rate.
Check the owner-occupied school levy treatment
South Dakota gives qualifying owner-occupied property a reduced school general fund levy. The classification is handled through the county Director of Equalization. It affects part of the tax calculation; it does not remove all school taxes or other local property levies.
For your estimate: Confirm the property’s classification with the county and request the full annual bill estimate. Use the complete amount rather than subtracting all school taxes from a prior bill.
South Dakota Department of Revenue: property taxCompare Fixed Rate Plus with the first mortgage alone
South Dakota Housing’s Fixed Rate Plus assistance is structured as a zero-interest second mortgage with deferred payments. Choosing assistance also means comparing the associated first-mortgage offer with the agency’s other financing options, rather than evaluating only cash needed at closing.
For your estimate: Request both loan estimates and the second mortgage’s repayment terms. Add any assistance balance to your debt planning even when it has no current monthly payment.

Using local estimates in this tool
The tax field multiplies the home's price by a percentage. If your assessor estimates an annual tax bill, divide that bill by the entered home price and multiply by 100. Do not enter an assessment ratio or millage directly. For example, an illustrative $4,800 annual bill on a $400,000 price corresponds to 1.2%; these are not local averages.
This payment includes principal, interest, property tax and home insurance. Budget mortgage insurance, HOA dues, maintenance and closing costs separately.
Official resources and next steps

How to Use This Mortgage Calculator in South Dakota
Enter the price of the property you are considering in South Dakota, then adjust the down payment and rate. The payment combines principal, interest, property tax, and insurance. It does not include HOA dues, maintenance, or mortgage insurance.
For example, at the illustrative price of $272,000 and 6% down, the base loan is $255,680. These are calculation examples, not a statement about prices or typical buyers in South Dakota.
Compare the same home under different rates and down payments. A lower monthly payment from a longer term can still mean more lifetime interest. Confirm taxes and insurance for the property before relying on the estimate.
