A few years back I used to argue with people here at FR who were out there borrowing every dollar they could on some house that was priced twice it was worth. And they were telling me how dumb I was that I wasn't sinking every dollar in it (my primary home) so that I could then flip it in 4 or 5 years when the note comes due and make $$$$$$$. The fact that I bought, and paid for a home on a golf course and had no debt made me just a stupid old school guy.
Those freepers might be a little worried in this day and age.
