First, look at your purchase agreement. If the home was sold "as is where is", you will have a harder time recovering against the seller. However, if you can prove "fraud" on behalf of the seller, the "as is where is" clause can be overcome. Fraud is when the seller knew of a defect and failed to disclose/hid it. This sounds quite likely in your case, but I would need more facts.
Depending on whether your contract is "as is where is" and the nature of the defect, you may have a suit for breach of contract, fraud, and redhibition. Redhbition means you file a lawsuit asking to "return" the house to the seller because the nature of the defects are such that it is not fit for its intended use, and/or you would not have bought it had you know of the defect.
Good luck,
