Happy New Year - Septic systems - knowing what questions to ask when selling or buying to confirm that the system is working properly

An issue I ran across with a home that was sold by another agent where incorrect information was provided to potential home buyers on the validity of the home's septic system and the permits of the addition to the home. Even in our very competitive market, it is always best, as a buyer, to ask questions before buying a home to confirm that what the seller is stating is true and correct, especially when it comes to the home's septic system.
