Andrea,
Consider using Redfin to search and Auburn is some what reasonable. The markets's pretty hot this time.
We bought a four plex in December of 2013 which was the very end of the crash in the Seattle area. The market started going back up a year later and is now touchable for us. Two four plex units across from us sold this summer for $150k above the 2013 price. They sold in four days and over the asking price. This is not to discourage you but to show you where the market is.
Remember you make all your money when you buy. A good, quick rule: you need to be able to make 1% of selling price in rent for it to be considered. We're not buying in this market we're saving and getting out of debt at this time.
We buy when the economy is terrible and unemployment is high. Unless a great deal comes our way. Remember this is a business.
Since you haven't started and may need some resources. You can look at our website Soundtenement.com and at Washington's RCW 59 landlord and tenant act.
Good luck!
