I checked out Allentown, PA to see about local meet ups?

I could be wrong but you’re should probably be careful with letting your potential personal biases interfere with it.If they meet the requirements together they’re in.

Going by the book of Brandon, my strategy is more focused on working in the corporate world while investing.I’m hoping to meet a lot of people here and hopefully people around the area.

I plan on attending his meeting tonight for advice, tips, tricks, and networking opportunities.

Be sure to connect with the local REIA groups - and when you visit plan around their meetings to meet and connect with local people who might have some of those 200 doors you are looking for.

Just thinking ahead another step... if a cosigner doesn't meet the standards I've set forth (lack of income, subpar credit, etc.) would it make sense to move forward with two instead of three cosigners, or should I require that the student find a different cosigner? 

You could counter will longer terms, lower payments, but keeping your asking price intact (if that solution meets your needs, obviously).

Meet ups?

If they don't meet your rental criteria, don't rent to them!

This all done without ever meeting face to face.
