There’s also those that use any equity in their house as a revolving credit door - my aunt is one of these. As housing prices went up before the bubble, that increased her theoretical equity. She then refinanced to cash out that equity (for whatever reason) - pay bills, go on vacation, whatever. (I didn’t say it was a *good *idea.) She’s done that two or three times, IIRC. She’d have paid off the house years and years ago, if it wasn’t for all the refinancing. That could be a source of the “paid for it four times already” idea.
Of course the whole “4 times over” part could also be hyperbole to up the fun of flinging poo at JP Morgan.
