You’re not the only one. I have to wonder how anyone could seriously think they are entitled/competent to buy another property while they are underwater on the one they are living in.
And, what bank is going to loan them money when the financial documents are presented? This isn’t Costco, where you can take items back that you buy in bulk (after you’ve ripped ’em open) because the smaller, cheaper version just showed up at Vons.
