When it comes to selling homes, Jacksonville, Florida, real estate agent Todd Arnold likes a challenge. He recently brought "Nightline" along to walk through some of his most unusual listings, including this home for sale. "I don't think about the homes I am selling," he said. "It's the buyers and the sellers I am helping." The homeowner maintains they did not want to be in this situation, and tell ABC News that they lost their life savings and retirement in alleged Ponzi scheme.
