You will need a lawyer.You will need an appraisal.You will need a home inspection.You will need title insurance.You will need a contract with the Seller.You will need some sort of partnership agreement if not a bog standard common law agreement as defined by your state.You will need a survey.You will need to heed the advice of the attorney in whether you need any other documents, and in what any document must provide for.You will need to have in your above documents what happens if you don’t like what is revealed or if there is a failure to get a document.The presence of a real estate agent is irrelevant to those things.Do NOT focus on saving the commission.
