I went to UW Seattle...
1. There is plenty of housing around campus (5 block radius) that are not operated by the university and they are cheaper, even for studio or 1 bedroom. In fact if you paid the same price that you would for an UW apartment you could get something far nicer at a private complex. It will also not affect the university feel or social aspect if you stay relatively close. If you really wanted the social aspect then you would find room mates anyways. The only benefit to UW owned complexes is all utilities, UW network for internet, and UW cable tv.
2. Do not park your car with UW, you CAN get other parking at the other complexes in the area. I lived at nordheim and parked my car on the streets for 2 whole years. You just have to figure out where to park and maybe do some creative thinking.
3. Part time jobs are great to make some side money. Find one where you can perhaps study as well. Helpdesk jobs in the library or computer labs are great for this. However, all students know this so openings are scarce. I used to work in the HSL Library in the computer lab helpdesk and it was great to be able to study 80% of the time I was at work. Keep your eyes open, network with current employees, and just keep trying to get at the openings available.
Any other questions, non-whiny, PM me...
