If I had inherited a property that I was renting from my mother, do I have co-owner rights if the property is still in succession?

I had inherited a property that I was renting from my mother. It is a two unit property that was purchased by my mother (sole owner) for I to live in one unit, (moved down April 2015) and she was to occupy the other. Eventually, she died October 2015 after she went in August 2015 for heart surgery with major fatal complications. That being said, she had left the property per her will, at her death be distributed in equal shares to me and my sister. My "sister" is the executor, wants to sell the house and has gotten me evicted for claimed lease violations. My question is does not the fact my mother granted me the ownership in the property at her death, that null and voids my lease as a renter? And although I have heard that I am technically not an owner yet because title has not transferred but is being sold instead, and the only rights I have in the house is to get half when it sells. Do I not have more rights than that? Does the fact that the will clearly states the property is to be distributed granting me ownership, and not just an interest? I am dealing with an extremely spiteful, vindictive, difficult person my sister. Her attorney is even worse, he has submitted full on perjured statements to the courts (I have a vast amount of documentation proving his statements are outright lies) they have denied me information I, (and even my attorney at the time), had been asking for nine months and the information on the estate and the home itself to enable to see if I could buy her out. It took nine month and a court order for me to receive the appraisal, and the mortgage/insurance information on the property. Despite my love for this house (it is a great place, but even more importantly the sentimental of this house).
