Fraud and Non-Disclosure in Residential Real Estate
In Florida a seller has an absolutely duty to disclose all known facts and materially effective value to property that are not readily observable by the buyer. A seller cannot stick their head in the sand and answer, "Don't know," when they know for a fact that there is a problem with their property. Even if the house is sold as is, the seller still that obligation to disclose any defects to you. I would recommend consulting with an experienced Florida real estate attorney if you think that the seller has lied or omitted an answer on a defect in the property.
