Whats the diffrence between rent to own and contract for deed?

my " landlady" is trying to evict me. She is giving me 15 days to pay what i have in default or be out . I asked if i was going to get a legal eviction notice. She claims the hand written piece of paper is all she has to give because she claims it is a contract for deed and not a rent to own . however she refuses to give an exact amount of default and refuses to show a title showing the property is in her name . what legal recourses do i have?
