renting indevidual rooms

[Brad Pietrzak]

I just had a buddy advise me to house havk i agree with it. Ive been looking for duplexes for a while now have a few in mind for my va loan. He also said when you get one try and rent each indevidual room out if you can to get more money so your start in real estate investing goes alittle smoother. How would i go about renting each room exept mine in the duplex work? Legally. Can i do it on both sides? Im really curious about the legalitys of it?
