I'm mainly interested in the outlying areas like Banks, Forest Grove, Scappoose & St.

Mainly high credit card utilization.

My main focus is to provide great service for managing and leasing rental property.

Would it be feasible as a flip (not my main interest)  or to get the second unit rentable and producing income and refinance it once it is cash flowing?

I attempted to research properties, mainly in the IE, Riverside area, but the property descriptions were difficult to discern, w/o the background and no experienced person to reference, I didn't pursue it further. 

While real estate investing is the main goal and line of work I want to be in.

Is there a way I can do this on my own, for mainly just basic research in the beginning to be able to cross out the ones that are not financially wise at the time?

You're main deflationary risk with rentals is always population decline in the city or nieghborhood where you have rentals though.  3.  

Main expenses would include closing costs (loan origination and fees, and title fees).  

My interest in Rochester is mainly due to the potential cash flow.
