What property-tax rate does this South Dakota mortgage calculator use?

It uses South Dakota's effective real-estate tax rate of 1.06% of home value per year, from WalletHub's "Property Taxes by State in 2026" study (median tax payment ÷ median home price), as of 2026-02-17. South Dakota property tax is actually set locally by county/city/school district and varies within the state, so treat 1.06% as a statewide average estimate, not a quote for a specific address.

How much is homeowners insurance in South Dakota?

The average homeowners-insurance premium in South Dakota is about $3,760/yr for a policy with $300,000 dwelling coverage — above the $2,543 national average — per Insurance.com / Quadrant Information Services data as of 2026-03-20. Your own quote depends on the home's rebuild cost, age, claims history and the coverage you choose.

What is the total monthly mortgage payment on a $400,000 home in South Dakota?

On a $400,000 home with 20% down ($80,000) at 6.5% over 30 years: principal & interest ≈ $2,023, South Dakota property tax ≈ $353/mo (1.06%), homeowners insurance ≈ $313/mo. That is about $2,689/mo total (no PMI at 20% down). Use the calculator for your own numbers.

Does the calculator include PMI?

Yes. If your down payment is under 20%, it adds private mortgage insurance estimated at 0.5%/yr of the loan balance (the typical conventional-loan mid-range; actual PMI runs roughly 0.2%–2%/yr). At 20% or more down, no PMI is added.

Estimate only. South Dakota property tax is set locally (county/city/school district) and varies within the state; the 1.06% rate is a statewide average. Insurance is a state average for a $300k dwelling; your quote will differ. HOA dues and closing costs are excluded. Not a loan offer or tax advice.
