Chris,
We live in Gresham, a few miles from Portland, but basically the same thing.
I don't know rent things, but tons of apt's, townhouses, houses for rent around here.
Mabey check out,
www.oregonlive.com and look in the classifieds.
Cable modem (comcast) everywhere here, also dsl, but a bit slower..
If you need any help, let me know.
Todd
