Getting a Mortgage in South Dakota: 2026 Guide

The Sioux Falls metro (Minnehaha, Lincoln counties) anchors most of South Dakota's mortgage volume, with steady move-up and first-time buyer activity. Pricing has risen materially over the past several years as the metro has expanded.

Rapid City (Pennington County) is the second-largest market, anchored by Ellsworth AFB and tourism around the Black Hills. Smaller cities (Aberdeen, Brookings, Watertown, Pierre) anchor regional submarkets at lower price points.

South Dakota has no state income tax, which often gets compared to higher-tax states. For mortgage qualifying, what matters is gross documented income and the actual property tax line.

For 2026, the conforming one-unit loan limit in every South Dakota county is $806,500 and the statewide FHA one-unit floor is $524,225. There are no high-cost designations anywhere in South Dakota.

At typical South Dakota price points, the agency cap is essentially never the binding constraint on a purchase.

South Dakota's effective property tax rate runs around 1.17% of market value statewide. Local mill rates vary by county and school district. Recent property tax relief legislation (including the owner-occupied classification's reduced school general fund levy) has reshaped some of the credit dynamics.

Always pull the actual county tax line for the specific parcel rather than running a percentage of purchase price and confirm the owner-occupied classification.

South Dakota Housing Development Authority (SDHDA) runs the dominant first-time buyer first mortgage program family in the state. The First-Time Homebuyer Program pairs a discounted-rate first mortgage with optional Down Payment Assistance for income-eligible buyers.

SDHDA also runs the Repeat Homebuyer Program (for non-first-time buyers in some target areas) and the Mortgage Credit Certificate (MCC) program. Funding and parameters are reviewed periodically.

South Dakota has heavy eligible-veteran demand around Ellsworth AFB (Pennington County) and the broader Sioux Falls metro veteran population. The 2026 VA county loan limit in every South Dakota county matches the conforming baseline of $806,500.

VA funding fee on a no-down-payment first-time use is 2.15% of the loan amount; subsequent use without a down payment is 3.3%. Borrowers receiving VA disability compensation are exempt.

Plan for buyer-side closing costs of roughly 2 to 3% of the purchase price in South Dakota, plus prepaid escrows. South Dakota charges a real estate transfer fee of $0.50 per $500 of consideration on the deed, customarily paid by the seller.

Standard purchase closings run 30 to 35 days. South Dakota allows both judicial and non-judicial foreclosure; most residential foreclosures use power-of-sale.
