Three years after I retired the mortgage I had mostly paid off before my divorce came up for possible refinance...they (credit union) told us that we qualified to borrow $350,000...my ex wanted to borrow that and payoff the existing mortgage and buy a vacation home. Unlike her I had been following the financial situation and bluntly told her we were NOT going to refinance....had I done that odds are I would be living in a rented apartment now.
It never fails to amaze me how the uninformed and clueless are the ones who want to borrow money for the present while living in the future. May not have any bearing on my thoughts, but: Several years after the GFC my brother bid on a foreclosed house that had a market value of maybe 85 grand before the GFC. The loan outstanding on the property was about $178,000....now, who in the right state of mind would loan 2X the actual market value on a property and who would be stupid enough to borrow that much???
