He had a for-sale-by-owner sign in his yard and I told him I'd buy his property. He said he'd give it to me for $45,000, half down and he'd carry half at $350 a month. I agreed. He said there were two liens he had to pay off and if i would give him $20K secured by a note on the property, he'd use that to pay off the liens and we'd close the deal with the note being given back as part of the down payment. The remaining down payment money was to be paid at closing. He told me he felt like we were partners because I was helping him. He helped me to move my belongings in, along with my food supply, and tools and stuff I sell to make a living. Then he went crazy and told me I could not return. He stopped communicating. He never made a payment on the note. I need help.It turned out there were more than $20K liens more than he said there were. One of them was paid by him but he refuses to file the paper saying so. He has been squatting there making no payments to anyone for years. I am without income except from selling the things he is keeping away from me that I need to sell to make a living. He won't let me come get my stuff, nor will he honor his agreement to sell per his sign-offer, Now he's taken in a woman to live there with him.
