You may get even higher cashflow in some of the northern parts such as Torrington, CT but growth in those parts may be limited compared to Central and Southern CT. 

Southern OR invester here.

I have also started in areas where I have someone I could get to be my eyes, so Southern Indiana (Evansville, etc.)

I've been in the Western-Southern side of Wake County for a while now. 

it is on the southern outskirts of Houston where the lot sizes range from 1/2 acre to 2, and a few at 4 or 5.

Anyone in the western Kentucky, southern Indiana markets?

Because northern Michigan is nothing like our southern portion of the states reputation......

Southern Adventist University, Amazon, VW and McKee are big economic drivers in the area that I don't see going away soon.

Even though I live nearby to the Poconos, I prefer investing in the Southern US (way higher year-round occupancy rates & way more money to be made) but if you’re really intent on buying a property in the northeast, remember that the 30 million people in the nyc area tend to vacation more in the catskills, hudson valley, berkshires, adirondacks & green mtns (vermont) more than the poconos.

there are plenty of properties that still cash flow. we just listed a 4 unit in southern orchards on the south east side of columbus that someone could live in and offset their complete mortgage, as you get to better areas though that thins out. if you are looking in Class A or B it'll be difficult to completely cover mortgage. areas like 43201, 43202, suburbs, and parts of the urban core that are the most desirable.
