here's my take (i actually worked for housing to save my self a shit ton of hassle).

1) cuz GT makes a living off of raping their own students, u'll learn this in the classrooms once u get there as well one idea is if ur a frat kinda guy, join one and at least u can park near the house.

2) i'd recommend the aptments on the west side or harris on the east side (gl getting in though, it's def one of the better places to stay on east side).

3) u've got a parking deck on both sides of campus as well as small lots and even some roadside parking all over the place.

4) very slim chance of getting both the place u want to live and park, however if u can somehow manage to get a parking pass ANYWHERE, u might be able to trade with someone that has recently moved or something.

5) housing chances and locations for transfer students are actually pretty good, most get put into aptments because they're considered upper class and easy to fill in 1 room vacancies in a lot of the aptments.
