 The gain on this, if you have a 401k and you leave work and you roll that into your IRA, you don't pay tax on that money. You only pay tax on that money when you touch it. And the same thing can happen with real estate. There's a little more to it than just a 401k rollover, but it's the same concept. I've got money over here and I haven't paid tax on a certain amount of it.
