get a real estate license and do it part time.Trust me.Its a few grand for every house you sell.My cousin does it and he also has a real job.Always ends up making a few extra grand that come in handy.Downside= You drive people around and end up wasting gas if they dont buy anything but its still a good deal.Just do it on the weekends and on evenings when most 9-5 folks go house hunting.
