If you don't want to go through the hassle of buying a car you can get a crashpad with your own bed for $350-$400/mo in Isla Verde. As your schedule improves you may want to opt for a "hot-bunking" situation for as little as $140/mo. If you plan on keeping your place in the states after 6-7 months you'll probably only need a crashpad 1-2 nights a week.
I currently have a 2 leg commute to the midwest and am finally going to the jet next month (after 17 months of waiting). I am able to commute the entire month without having to spend a single night in the crashpad.
Good luck,
P.S. Eagle ain't worth it, go to COEX or Air Wis
