" The first thing you hear is often an indication (though not proof) of the kind of tenant they might be. If the first words you hear after saying “hello” is a voice yelling into the phone, “How much do I have to have to move in?” you can assume the tenant might not be a great fit. (We get these calls weekly!) After all, they are more concerned with getting in anywhere than even asking to look at the property. "
