I have properties right on the border of PA in Warren County NJ and I am having a hard time finding a management company to service these properties.

I have a 1/2 acre property with numerous trees (mostly mine) bordering the yard. 

Even within these zip codes there are little pockets of nice rents, older homeowners and kind-of bordering crime areas.

My family living in Mpls and my in laws farming on the South Dakota border MIGHT have had something to do with that.

The closer to the border the better.

If you are looking at SFR you may want to step over the border to NW Indiana, which is still in the Chicagoland MSI, but with substantially more landlord friendly, easier price points, nice returns, and lower taxes.

I'm here in the Lehigh Valley and have been actively looking at Easton and am about the close on a multi right on the Wilson border and am pursuing a short sell in South Easton. 

What kind of borders would you put on Dubuque?  

Sacred Heart University sits on Park Ave on the Bpt/Ffld border.
