Thank you so much for the responses! I am running scared from this property. I wanted it as a winter house for retirement but I just don't want to deal with this situation. A sherriff's officer told me about the fines. A 500 dollar fine for me for the first 72 hours to clean up the mess and a warning letter to the renters. They said I would have to clean it up since the renters never do. I told her that if I go in to clean up someone's pot grow, something as small as a bullet could put a quick halt to that procedure. She thought that was hilarious, I didn't.
The guy that is buying the property is not the renter, I don't know anything about him. I found out about the pot farm from a niece. The 100 to 150 value was for cash price after evicting the renters and doing some cleanup. The value of the house after being fixed up is about 250. It is a stupid move to sell this way but I bought the house for 50 thousand, collected about 100 thousand over the years and getting 110 thousand for selling. I understand that I am sounding like an idiot for selling this way but I feel much better about getting a place close to me so I can keep an eye on it and not have acreage with the rental to have a nice big pot grow.
Thank you so much for all the information and help. I appreciate it more than you know.
