However, my wife and I would need some help.The choice was to look in the Akron, OH area where my mother and her boyfriend, a general contractor, life.

Became a registered nurse and moved a whole 30 minutes to Pembroke Pines for about 4 years.

I am interpreting this as a gift of equity, which means that your wife's initial basis is half of her mother's basis. 

Hey @Petra S JordanAs for the question of legality, I can tell you that in order to rent out out a mother in-law apartment or accessory apartment you are required to owner occupy the home.

Before this I was working a 9-5 in a nursing home which taught me patience and hard work.

The mother of a friend of mine passed away and the children didn't want to keep the property.

An elderly tenant had trouble coming down 2 flights of stairs to let in her visiting nurse -- an electronic keypad entry lock fixed that.

@Thomas S.....I swear you are like a "brother from another mother" when it comes to your posts on BP....99% of your posts are like the words coming out of my mouth...seriously.....not kidding.....But I would argue that in some cases it may be a better financial decision to do cash for keys vs a legal eviction.
