I did add a clause about personal property and plan to go through the inventory with the new tenant, who will sign upon moving in.

If anything, have a small sign in front of the house that says who the builder is and phone number (that's common for contractors to do, and also so that neighbors feel they have some to call if there is dust blowing from the site or whatever), and then you may have people calling you asking about availability (people always want something more that they had to chase and can tell their friends the story of how they got the house). 

Why do people willingly sign up for such nonsense?  

Sign up for my course and use my proven system to become a top syndicator."

Then they won't need an upfront payment for work they haven't provided yet.Also, get a signed contract, copy of the drivers license, contractor's license and be added to their liability insurance.

I even have a creative deal signed if I don't flip the contract.The purchase would be 300 + closing costs. assignment would be 15.

Put down deposit, lease isn't signed. 

Keep in mind that you will probably be required to sign a personal guarantee of the loans.

In Alabama the utilities being turned off is a sign of abandonment so we would not have put it in our name.

You have no case.If the lien was bc seller has a brother on title who won't sign off then you're owed your EMD back.
