My negativity has been an issue and I have begun to see the light with  positivity.

Should I give them a 3 day eviction warning telling them to pay or else I will evict them or should I just start the process? 

Hopefully you can shed some more light on how it went down.

At least with a letter of intent you're theoretically +/- light repairs when it comes to a purchase price.

I don't do flips and I don't do complicated deals so consider my opinion in that  light.

The town has one of the big x's on the front of the house warning the fire fighters not to go in if there is a fire.Its also one of the few multi families in this particular town.

The City does the plowing and maintains the streets, lighting and parkways.

The light on the floor in the third one makes it look like the floor is gouged and the cabinet backs look really bad from this angle. 

Variables that impact production (lighting, co2, pests) are more easily controlled in an indoor environment.

It exposes some very questionable tactics in your business model (if you can call it that), and bragging about almost ripping off an elderly widower through the unlicensed practice of real estate does not paint you in a positive or professional light.
