Regarding questions:
These are buyers and they really don’t need to be concerned but if you feel more comfortable answering this is easy.
What do for a living? Answer: Whatever you do or I’m taking some time off.
How long have you owned it? You can answer this many ways: pushback answer: Why? or Id rather not say are you interested in buying or not?
Nice answer: It’s been in the family for years are you interested? Don’t waste time on questions that serves no useful purpose. Your offering a property up its always best to remain friendly but don’t give away information that leads them to think you are flipping.
