Back about 7 years ago we used to force Greentree to pay the back lot rent because we didn’t care if the home moved out as a new one would move in when the lot was vacant. Once they received notice that the lot rent was due they were forced to pay via state law. However, those days have changed and as the park owner you are in a better position to buy the home as long as you open your lines of communication with them. Plus you don’t have to move the home but you end up eating the back rent.
To my knowledge Greentree does not resell to individuals and rewrite notes - it is cash and as-is to dealers and park owners.
