Heads up for you people from out of state: Are you folks planning to live in the dorms or "other" university housing? If not, you need to be hunting a place to live, pronto.
The Marcellus shale gas business has taken up all of the rental housing in the Washington area and was moving into former student housing in the Waynesburg area as of last year. Landlords can rent to shale guys for much more money than they can get from students, so students are getting booted out.
Most rentals will be apartments that are carved out of old houses, unless you want to look more toward Morgantown or perhaps at apartments in Washington. I do know that rental houses started at $1200/mo plus utilities for small shabby houses in Washington area on Fall 2010. Nice new townhouses with 2-3 BR are $2000/mo + utilities (or more) and they want tenants to have a gross income at least 3x the monthly rent. Landlords are also not accepting pets, because they have plenty of tenants and they can just say no to pets now.
I was at Washington PA Hospital SoN but one of the major reasons I wound up hating it was that I had to rent a room there instead get a house or townhouse. I am a mature adult who sold a home and I have pets, vehicles, and furniture. A rental room was not what I needed. But I was stuck with that due to the lack of safe and available housing.
I don't have any contacts there, and I am no longer in WashPA. My advice, if you want off-campus housing, is to start contacting realtors now.
