FESTUS, Mo. (KSDK) - A cave house hit the auction block Sunday in Festus.
Bidding on the unique residence started at $100,000 and quickly climbed to $220,000.
However, sellers Curt and Deborah Sleeper are still accepting bids on the cave home for another two days.
If they do not receive a more satisfactory bid, they will attempt to sell the cave home through more traditional means.
