Now let me throw a monkeywrench into the pot to see if your suggestions change:1.  

in the city where i work, there is a company owned by koreans and they made the engineers go out and put asphalt in the pot holes because they were too cheap to fix the parking lot.i have not heard about having to go out drinking with the boss.

Perhaps Grandma is tired of the behavior of the teens too and will voluntarily ask the grandsons not to come around any more.  

If you have $50K, instead of putting it all into a single property, split it into 4-5 pots of money to fund 4-5 leveraged deal. 

It is great that your husband works in construction as labor is always the biggest cost associated with rehab and my wifes commision sweetens the pot every time we do a deal.  

Any advice on how to get her out once I receive the deed if she won't leave voluntarily?

Your tenant allowed the person to live there for at least a year, and so did you by not doing anything to remove him once you became aware of him being there.Therefore, he has established residency there and would need to be evicted (if he had not already left voluntarily). 

So my question/discussion is concerning Tax incremental financing (TIF), this seems to be a big pot of money in many areas.

By bright future, I mean 1) Population growth2) Vibrant tech community and tech jobs3) Sustainable Job growth and entrepreneurial soil.4) Great year-round weather, mild winters & an excellent lifestyle.5) Low business, sales, and property taxes6) International city7) Immigration gateway city, melting pot of all cultures8) No history of natural disasterAtlanta possesses all 8, and is known as the NY or the LA of the South. 

I hope he turns out better then the last bad apple who is voluntarily leaving after moving in last month for refusing to have his electricity turned on.
