looking for lawyer who takes contingency cases for home purchase which upgrades done with criminal negligence and failed to disclose mold and asbestos

The as-is clause does not preclude suit, as the seller has to disclose any facts or conditions they know about that materially affect the value of the property. Typically, a seller is not required to disclose obvious defects such as a hole in a wall, but is required to disclose hidden or "latent" defects of which they are aware and which a reasonable inspection would not reveal.  The biggest problem with these cases is proving knowledge of the seller, although it seems like that may not be a problem in your case. From your posted question, I can not determine what "all repairs" means or when they occured. Any attorney you contact will need to know when the purchase occured, when you discovered the problem, to see the purchase contract, inspection report and documentation relating to any repairs you have made. They may also want to see your homeowners insurance to see if there is a possible claim under that insurance. Lastly, what is it that you are seeking- monetary damages, to get out of the contract or something else? In terms of a lawyer, you should contact a construction law attorney.   Good luck, Michael R.
