Does she in fact have the ownership of that property or would the lady who has bill of sale?

I ran across a piece of property (little over one acre) with a trailer house in the country that really should have been condemned but after asking around I found who owned it and asked about fixing the place up and renting it. I was told sure thing and rent was $300 a month and would take off for repairs I did. I was told that if I wanted to buy the place she would take $10,000 and it would be mine. I fixed the place up completely and then started looking into buying the place. I couldn't get a loan because she did not have a deed to the place. I went to courthouse and found out that the place was actually in someone else’s name. There was a deed of trust signed in front of a notary where the place had been given to a daughter by her step dad. It had a stipulation at the end that said this piece of land could not be sold. Well I had a huge falling out with the lady I thought was the owner and ended up not talking to her or even paying rent for 19 months. During this time I could not locate the daughter. The lady ended up taking me to court to evict me and it was there that she produced a bill of sale for the same property by the same stepdad who had already given it to his stepdaughter. But it was not notarized and it was dated several years after the date on the deed of trust. I finally got hold of the daughter and she verified that her stepdad had indeed given her that place and she didn't even know her stepdad had then sold it later.
