And does that company handle all legal matters (such as payment agreements) using an attorney?

IMO this is the best, most fair and correct way to handle it.    

My question is, with the longer term rentals now being handled by me, what steps should I take to protect myself?

Tell them how you handle multiple applicants.

How will distributions for completed work be handled?

Yes and you said you did not handle evictions in this area.

We have currently moved to San Antonio and are looking for an attorney to help us set up our San Antonio holding company and can also handle multi state holdings which include Wyoming, Idaho, Arizona, and land in California.

Use non-keyed for the handle to avoid lock-outs.

I have properties in two different States handled by PMs that charge a 10% flat fee for their services.
