As I recently posted, South Florida has always had some of the highest numbers of real property fraud in the country. 

In order to keep the liability protection on the homes owned through the LLC, I need to maintain "separate identities" between myself and my LLC. 

First, if you put a property under contract when you don't have both the intent and ability (funds) to close on it subjects you to charges of "Fraud in the Inducement" (a tort). 

A professional manager will:1) Limit the risk of lawsuits and risk on tenant safety2) Perform home turns between tenants quicker than you can3) Screen tenants with advanced knowledge on Fair Housing Laws, identity theft, and filtering false references4) Be able to monitor and handle scams5) Provide you with the quickest eviction process if needed6) Have problem solving skills, so that most days you don't even know there was an issue because it resolved with little or no involvement from you.7) Have resources that include eviction attorney, repairs, cleaners, appliance repair, screening companies, mortgage properties, emergency line coverage. 

Not to condone mortgage fraud, but I BELIEVE the stipulation is you need to plan to be there for at least 1 year. 

Using owner occupied mortgages would allow you to purchase with a lower down payment, but to use it a few times would require you to move to not commit mortgage fraud. 

At worst we report it as attempted mortgage fraud.

In the situation you described, renting a million dollar house at $100 a month would be considered tax fraud.

They said a lot of people say they are going to live in one of the units but never move into the property (which is essentially home occupancy fraud).

Those numbers are identical to the neighborhood I live and invest in.
