You can get property managers who specialize in it and likely you'll pay the same percentage you would for a family.My suggestion would be rent to a group of friends, professionals ideally but college students too.

I have seen a few programs out there that specialize in 2nd non-performing notes.

But if you're looking to determine what market rent is... look around at other properties that are for rent and similar to yours, hire a professional management company that is familiar with the market that can give you an accurate rent number, or talk to a Realtor that specializes in rentals.  

I would create one if not, and make cheap ads, maybe an ad with a move in special.

You can also work with others.To join a team often you need to have special skills.

I would like for them to be investor friendly because that's the area I would like to specialize in....

@Catherine Aubale Epstein is a good broker that specializes in this!

Townhomes or condos - you are paying HOA fees each month which eats into your return and subjects you to special assessments.  

I have a law firm I can recommend, with which I have no affiliation, that specializes in real estate, tax, and asset protection law.
