But who knows.....When I talked to them a couple of months before, they told me they can extend my term by "a few months" and repeatedly ask me to shop for refi and document it and send proof (that I shopped around) to them... yes even with this equity, it is NOT easy to get a lender...

Do I need to show proof of funds or the buyer
