I inherited her when I bought the house and later realized she was playing games with the other landlord other landlord didn't tell me about this until after I closed. she's now playing similar game with me and seems like the courts system is helping her to do this.

Real estate is a relationship game.

If you're taking into account the ballpark number of $900/mo (or whatever you're planning on paying in rent) x 24 months (just an average based on new build timelines and playing the waiting game with material pricing etc) that would be about $21K ish- or about half or 1/3 of the cost (this will be area specific to you of course) of a small modular home maybe. 

You've got Ohio State parents looking for rentals during parents weekend, football games, graduation,  etc...then you've got Cedar Point!

Cash flow is the name of the game. 

I’m learning a bit myself, but I want to at least share a couple of my initial thoughts.First, an asset will make you money but a liability will cost you money.Next, I see two ways to look at the situation: a) the short-game, b) the long-game.The short-game is to view the property/opportunity as a way to pay less while owning the building.

It's a little late in the game, but get what's called an Estoppel Certificate from both Seller & Tenant.

Maybe you watched game tapes.

Don't be anxious to get into the game.

It's a bit of challenge finding good folks for this building given the area, but the long game might be more synergistic.
