 Every time I buy another one, I think, wow, I'm going to really expand all the fun things I do. I never can expand it fast enough. But I do it anyway because the money builds return. You put your money in a 401K, do you get any return? No. How much did your 401K pay you this year? Nothing. Last year, nothing. Year before that, nothing. In fact, you pay it. It's even worse than that. Can you imagine if I said, here's what I want you to do for a real estate deal. I want you to buy a rent house and not rent it.
