I think you have it right. If one wants to maximize it all, get a room large enough to keep your stuff, and claim it also as an office expense. You can claim a studio apt. as such, and so much space for business matters. Keep a home address, and you can claim your per diem on the road.
I just got kicked to the curb (at least it feels like it), and moved out of her house quickly. I got a room with a shared kitchen and bath and basement area to store extra stuff. Even in a suburb NW of Detroit, it is only $375 incl. utilities. I have a room large enough for large armoire, a large desk and TV stand, a small fridge, and a full-sized bed, and a chair to watch the telly. What more could one ask for? The lease is only 6 mos., and I can always get a one room apt. for about $150 more. Perfect!
