With facebook I can specifically target the ideal buyer I want to work with all the way down to income level, and zip code.

But you can be just as successful in a niche.

I do some private lending in some parts of Atlanta...feel free to send me details if you have a specific deal you're considering...

Several law firms have 'standard' forms where you can fill in dates, amounts, and any specific criteria. 

(I am okay with that in this particular instance as the property is REO and wholesaling with banks is not my niche quite yet).

Can I work specifically only with investors?

The management agreement you sign is with the brokerage and not that specific manager.  

It's okay to be different.A couple examples:1) If everyone is going after Pre-Foreclosure Lists, or Probate leads, maybe you should attack Tax Delinquent Lists.2) If everyone else is contacting by direct mail, maybe you could get actually call, or knock doors.DARE TO BE DIFFERENT (you might fine that a niche acquisition strategy will serve you best).We wish you the best of success,Reach out if you have any questions,ADAM ADAMS

Any suggestions on who to specifically reach out to to help you define what your investment criteria should be?

Is anyone familiar with the RE market in PA? What are the areas to invest in rental properties? Currently, I'm looking at properties in Allentown. Low priced homes in small populated zip codes.
