We're also separated from the main crowd which makes us easier to find and more comfortable. 

I suggest having a separate agent for each as well.

->PropMgmtLLC - separate traditional single member LLC member managed by me, has its own EIN and bank account, has a contract with Cell1, Cell2 and handles all aspects of property management for property1 and proerty2, sends monthly invoice to Cell1, Cell2 and charges a $50/month management fee for each property.

I'm sure this process varies by state, city etc. but figured I would take a crack at the forums to see what I could learn.I've found a SFH in the Myrtle Beach, SC area that has a "mother-in law" suite that has been built with a separate entrance, separate electric meter etc.

I recommend separating your business from your personal life as much as possible.  

For an S or C, this is a completely separate analysis.Given that every LLC has a state fee, there would be an item of deduction. 

However, in your case, you have two individuals doing two separate 1031 Exchanges. 

I am a single female who is just about to separate from the military. 

The apartment buildings will be in a separate entity.

Without an 'out' clause it's very, very hard to get through to an amicable separation if things turn to sour grapes.
