You have listed a variety of issues regarding this residence, from the duties of disclosure of the Seller/Landlord under a Lease Option Agreement to the standards of care and possible misrepresentations of the Realtor and Inspector. You should focus your claims on three (3) areas: (1) breach of contract with the parties with whom you contracted; (2) negligence as against the parties with whom you share no contractual privity and (3) misrepresentation if you can prove that any of the foregoing parties made material misstatements to you.
