South Dakota closing cost realities

South Dakota's average effective property tax rate is 1.24%, and homeowners insurance averages around $3,000/yr. Both are collected in your escrow account and factored into the DTI your lender uses to qualify you — so a Conventional approval in a high-tax South Dakota county requires more income than the same purchase price in a low-tax state.
