There’s a well-established protocol that buyers and sellers are to communicate with each other solely through their agents and not directly during the course of a transaction to buy and sell a home. Here are two things you may not know.
Sellers can talk with buyers and/or their agents at open houses as long as they only discuss features of the house and not price or terms. They can also give their cell number to inspectors to answer questions that may arise during the home inspection.
At closing, buyers and sellers are advised to exchange contact info so they can be in direct communication later on for any reason. During a pre-closing final walk-through, I like to make the seller available to provide an orientation to the buyer to explain how things work.
