I've been doing a little research....
The laws in Oregon and Washington are very similar. Tenants do have rights...it seems they also have to look at any loopholes that might be exploited. One of those is the month-to-month rental agreement. It seems landlords can raise the rent as much as they please on a month to month basis. That law seems to apply anywhere you go, which is why people sign a lease. The other thing is losing one's deposit due to shady landlord "fees". I think this can be taken care of with a thorough walk-thru and perhaps photos of moving in, and moving out. You may still end up in small claims court
When I visited the apartmentratings.com site it was very disconcerting how many people feel ripped off. I think Dignan is right in dealing with smaller properties, and perhaps a small property management company. Even if the property looks perfect when you visit and move in...things can still change. I presently live in a complex that has changed with a few "party animals" that have moved in and changed the whole energy of a once quiet community. The landlords used to care, but have now allowed things to go to hell. My choice? Move. For $1000 a month I can do better.
It's sad that the good tenants have to pay for what the bad one's do...
