Perhaps you can even get your kids involved in the rehab process.

I believe you've gotten overly involved already. 

The option agreement is what gives one the option to buy the home without being obligated to purchasing it3- more involved process than simply signing a lease or a purchase agreementIf your main objective is to prevent breaking a lease, finding a property with "month to month" leasing may be your best bet. 

I purchased the property over a year ago at a Sheriff sale. I am now in escrow and the new title company which by the way resides in a different county is stating that the publication of seal performed by the law firm...

Sounds like your going through the right motions getting your attorney involved in drafting the lease. 

Having multiple LLCs is not likely a red flag, nor is the realtor being involved in the deal.

I currently operate out of my personal bank account, but was told it's a good option to set up a separate business bank account for everything involving this property (rent, any expenses associated, property management fees etc.)

@Gene Hacker Thank you, Gene! 

Is there a way that I can avoid involving an attorney if we come to an agreement in person?
