When somebody makes it very easy for you to do it by saying you don't really have to put up my money, you can lie about your income a little, or we'll give you 100 percent mortgage, you're going to do it, because everybody that's done it has been proven right. You have social tools, and you're going to feel like an idiot if you didn't do it, because the house cost more.
