I still teach at H&R in my free time (what little of it I have)..but dont know of anyone looking to split any kind of housing costs. There are lots of descently priced apartments in the area though.
However, and this is just an idea...you could hire on at one of the schools (H&R, DutchWings, Ascent) in houston but also pick up a line service job at an FBO as well until your business picks up enough to rely solely on your flying.
There are lots of FBO's in houston, especially hobby, where you could make some cash as well as alot of good connections.
Good luck.
