Moving from Washington to Portland

Hello I currently just finished nursing school and planning to move to Portland. I really don't know anyone and don't know much about it except it is a very beautiful city to live. I was thinking about applying for the residency programs at one of the local hospitals and unsure of which one has the best reputation and which one I would most likely be hired in coming from another state. Also I would like to know a little about what areas of the city are nice to live but yet affordable? Last question is would I be able to afford to buy a house in Portland on RN wages? Thats it! Thanks for everyones input
