An agent quoted me a Marietta price without seeing the inside. Should that disqualify them?

A price quoted without seeing the inside of a Marietta home should be treated as a rough starting estimate, not a serious number, since condition, updates, and layout materially change what a home is actually worth. An agent willing to give a real number sight unseen is either guessing or padding to win your listing, neither of which serves you well. A credible comparative market analysis requires walking the property first. Joel Boss will not give you a firm number on your Marietta home until he has actually seen it.
