In north/central NJ, 95% of serious arms-length real estate deals (i.e. not wholesales or  family/friend), attorneys will be assisting.

Hire an attorney and proceed with the eviction.In the future, I recommend you don't accept "landlord references" from friends or family members.

NY is a very tenant friendly state, so if he doesn't leave and she's on a month to month.

A good friend of mine has a real estate related service business he wanted to scale.  

He himself was a felon on parole, and his friend who was an addict, he was his cell mate.

Coming from other areas and moving here, I've found Kentucky to be very friendly in the out skirts however my experience is limited to Lexington and Southern counties.

It tends to hide marks better.Walls: Neutral tones like SW Repose Gray, Behr Swiss Coffee, or Moore Classic Gray are renter-friendly and modern.Trim and Doors: Use a crisp white like SW Extra White or Moore Chantilly Lace.Accent Walls: For a touch of style, consider an accent wall in soft blue-gray. 

My father and I have formed an LLC with another friend to start buying some rentals.
