Why is that a primary concern for you? Would it make you MORE or LESS interested in the property, for example, if the seller was moving for a new job? I understand that your interest might be lessened if the sellers were moving because the basement floods every time it rains -- but those sorts of conditions should be spelled out in the required Property Condition Disclosure. While we're on the subject, why are you moving from your current location? See, your primary concern should be the property you're examining, not the reasons that might underscore it. Talk to your Realtor about any concerns you might have, and good luck.
