Funny thing is whoever buys it, the second they do the country is going to come after them to either fully remediate the property or demolish the house and have it hauled away and disposed of in a biohazard landfill which will cost the new owners more that they paid for the property. The county doesn't want to do it because it will cost a fuck ton of money, so sell it, profit, then come after the new owner before the ink is dry on the sale papers.
