Timeshare Income

My brother in law is really trying out the real estate ladder. He's been all over the country looking at vacation properties and his latest venture is orlando timeshare buying. Since I have no idea how they work I'm not sure if he knows what he's doing but he thinks that he can make a lot out of it. It's really good for him but every now and then I can't help but be at least a little bit jealous since we don't have the money to do the same thing. At the same time I really don't want to deal with the things that can go wrong either. All he needs to do is rent to one bad tenant and it can make his life a pain. So really I guess I'm not all that jealous after all.
