Re: "emotional defect" laws
You call the same person you should have called before you signed the contract, a real estate lawyer. It always amazes me that people will call a lawyer if the get a traffic ticket, don't don't invest in one for probably the biggest purchase of their life. In jurisdiction where they don't have full disclosure laws a good real estate lawyer would have a full disclosure clause in the contract.
