Welcome to the BP community @Asia Butler! 

Daren, thanks for the excellent post.

We do deals in Hamilton and Butler Counties, and sometimes in northern KY.

@Robert Butler Adjusting the dollars per foot of comparables is never an exact science.

The Book on Managing Rental Properties by the TurnersLandlording on Autopilot by Mike Butler

Within the MSA, the cheap houses are to be had in four distinct locations: within the urban slums of the actual city, within the urban and suburban slums of the surrounding municipalities of Allegheny County, the limits of Allegheny County, and finally, in the surrounding counties, excluding $$$ pockets with strong school districts and a few purpose-built tax-haven bedroom communities just over the Allegheny County line (Cranberry Township in Butler County, where my brother lives).My target area for those $30K properties is just outside the southeastern limits of the city, which actually used to be very prosperous when the steelmills were running.

@Matt Butler, $500 cash flow per door is a good target for long term rentals.

For Butler county, it's $1178 for a 3BR home which seems high to me. 

My partner on a 32 unit (in Lancaster SC) and friend, @Wendell Butler, lives out there and may be able to direct you to some cool meetups in the Charlotte area.
