what is your question?
are you asking how does it work? or you are interested in renting to own a property? what is your situation?
in any case, all depends on the property, the market activity, the current owner, and if there is a special situation.
Among all, it is easier done in some parts of the country than others, even it varies from one county to another. Put yourself in the place of the seller! He will ask "what is in it for me?"
