That could be a PM or you can hire a person to work full time for you. 

Signing the lease demonstrates they agree to the terms and then you can hold them accountable.If you don't do this, then the person named on the lease and paying the rent could disappear and you would have no legal authority to charge the remaining three for unpaid rent.

I’m personally based in Houston, TX, and I’ve noticed over the years that a good realtor can do a lot more for an investor than just listing a property.

The key is to identify personal property from real property.

Personally, I bought a 3 bed single family home soon after starting my job and had two friends from college rent which covered my mortgage plus a little extra.

For in person connections try some local real estate meetup groups.

If you are just a plain person they usually must serve you in person. 

This could give you the cash you need for the purchase and also eliminate your personal guarantee for the loans.

@Leslie L Meneus, while the forums can be pretty good, in-person networking and sharing ideas is much more valuable.
