Naw... your sooo smart. Come on. Don't crawfish now.
Just what happened is what most people do. Yall try to sound smarter than yall are by repeating some thing you heard, from some one else, trying to sound smart.
That playing the interest stuff is bs when you apply real world, not book, numbers to it. Best.... absolutely best, case scenario is you have risked a whole paid for asset to make 1 or 2%... at best... if every thing goes perfect. That is re-dic-u-lous. You put up collateral at maybe $2 to $1 in order to make peanuts on that money... at best. AND, if you really are soo great at making money, it should not be any issue to put the money down since you should be flush with cash from all those profits. Real wealthy people are looking for places, like land, to squirrel away money.
The reality is most people who buy zero down do not have the available cash... and that's ok... but own that. Say I don't I have the cash to put down and fulfill my other obligations. Don't try to sound smart and act like you are playing some interest game that does not exist.
I have actually heard some legit reasons for people buying zero down but they all involved people being flat out honest with what they were trying to do... not hiding behind financial books.
