South Dakota Home Loans 2026 — Complete Guide

From 3.5% down FHA to state-funded down payment assistance — here is what home buyers in South Dakota can access in 2026.

South Dakota has no state income tax, and its property tax rate sits close to the national average — but the gap between counties is dramatic, ranging more than fivefold from one end of the state to the other. This guide covers loan limits, current rates, that variance, and the SDHDA programs available to general buyers this year.

The number people miss: South Dakota's effective property tax rate swings more than fivefold across its 66 counties — from around 0.44% in Oglala Lakota County to over 2.2% in Todd County. A statewide average tells you almost nothing about what you'll actually pay; the county matters far more here than in most states.

South Dakota Down Payment Assistance — SDHDA Programs

The South Dakota Housing Development Authority (SDHDA) offers down payment help through its Fixed Rate Plus option, paired with an SDHDA first mortgage.

SDHDA Down Payment Programs

Fixed Rate Plus3% or 5% of loan amount, 0% interest second mortgage
StructureDue on sale or payoff, no monthly payments, no additional fees
HAPI (Brown County / Aberdeen area only)$3,500, non-forgivable

3% or 5% — the tradeoff is your rate: Choosing the higher 5% assistance tier typically comes with a slightly higher interest rate on your first mortgage than the 3% tier. Both come as a 0% interest second mortgage with no monthly payment, repayable when you sell or refinance — not a forgivable grant.

The Governors' House Program is a different kind of help: Rather than cash assistance, SDHDA offers income-qualified buyers a subsidized, factory-built home (1,008 to 1,200 square feet), constructed in part through a state workforce program. It's not traditional DPA, but it can substantially lower the total cost of homeownership for eligible rural buyers.

New for 2026 — manufactured home DPA: House Bill 1113, passed in the 2026 legislative session, establishes new down payment assistance specifically for manufactured homes, expanding SDHDA's reach to a housing type not previously well-served by state DPA. Ask your lender whether this option applies to your purchase.

Eligibility & Income Limits

SDHDA programs are open to first-time and repeat buyers, with a minimum credit score around 620 and household income under limits that vary by household size.

South Dakota funds local government primarily through property tax, since the state levies no income tax at all — a tradeoff that keeps overall tax burden low for most residents but places more weight on the property tax line specifically. Rates vary dramatically by county rather than following a predictable statewide pattern, so always check the specific county rather than budgeting off a statewide average. Homeowners 65 or older or disabled, who've owned an owner-occupied home in South Dakota for at least 5 years and lived there 200+ days a year, can apply for the Assessment Freeze for the Elderly and Disabled by April 1 each year, which locks in their assessed value so future increases don't apply, provided the home's value stays under $514,500 and household income stays under roughly $56,595 (single) or $66,885 (multi-person). Sioux Falls, Rapid City, and a few other municipalities also offer additional local refund programs on top of the statewide options.

Frequently Asked Questions

Is SDHDA's Fixed Rate Plus assistance forgivable?
No. It's a 0% interest second mortgage with no monthly payment, but the full amount is due when you sell or pay off your first mortgage — it's deferred, not forgiven.
Should I choose 3% or 5% assistance?
The 5% option typically comes with a slightly higher rate on your first mortgage. If you need less cash upfront, the 3% option paired with a lower rate may cost less over the life of the loan — compare both with your lender.
Can I use HAPI's $3,500 assistance anywhere in South Dakota?
No, it's limited to Brown County and the Aberdeen area. Buyers elsewhere in the state should look to SDHDA's statewide Fixed Rate Plus program instead.
Why is South Dakota's property tax rate so different from county to county?
Property tax is levied and set at the county level, funding local schools, law enforcement, and infrastructure directly, with no equalizing statewide rate. Counties with lower populations or different budget needs can end up with dramatically different effective rates from their neighbors.

Bottom Line: South Dakota combines no state income tax with generally affordable home prices, and SDHDA's Fixed Rate Plus program meaningfully lowers upfront cash needs for both first-time and repeat buyers. Property tax genuinely depends on the specific county you're buying in, so check local rates directly rather than relying on any statewide figure.
