Illinois Underground ‘Caveman’ Home Built in 1977 Now on Market for $59,000

An underground house in Armington, Illinois, originally constructed in the 1970s, is now listed for $59,000. The property features rock‑lined interiors and circular windows, offering a spacious layout that remains largely unfinished. Buyers are advised to factor in renovation costs when evaluating the low asking price per square foot. The unique design could make the home suitable as a vacation retreat or rental property, but its unfinished state requires significant work before it can be occupied. The listing highlights the niche market for unconventional, subterranean homes in the region.
