Cost of Living & Housing in Interior

Interior's cost of living picture centers on a real, disclosed research limitation: the town's extremely small, 65-resident scale means no dedicated, Interior-specific housing or property-tax data was found this pass, so this record relies honestly on broader Jackson County proxies.

A real, disclosed housing-data scope gap

Interior's own minimal residential housing stock (beyond its lodging, dining, and gas-station businesses serving Badlands visitors) means no Interior-specific median home price was found this pass. This record applies Jackson County-level figures as the best available proxy, disclosing a real, wide cross-source spread ($54,600-$117,300) it does not resolve to one number (base record).

A real, disclosed property tax rate conflict

Jackson County's own effective property tax rate carried a real, disclosed cross-source conflict this pass found -- approximately 0.69% per one source versus approximately 1.43% per another -- neither figure Interior-specific, and this record does not resolve the discrepancy to one confident number (base record).

South Dakota's real, complete absence of a state income tax

South Dakota levies no state individual or corporate income tax whatsoever, applying in Interior as it does statewide (base record).
