Pagdi home sale of property

My mom passed away 2 years back. Earlier my younger sister was staying with mother, however, I used to take care of most of her expenses and visit her every weekend. When the expenses being unbearable, my sister ran away and stayed separately. I then had to manage my mom with 2 maids as my mom was dependent on aid for her day to day activities. My mom survived for a year or so and then passed away peacefully. Once she passed away, the sister who had left her, came back and has started staying in the house say 2 days in a week, mostly on weekends. I want to sell the house, however, citing financial problems etc. she is refusing to let me sell the house. I also have another sister who stays far away after her marriage and rarely used to visit mom. I need to know if I am in my right to sell the house? How can I convince her? I have tried talking to her to buy me out, however, she says I do not have the requisite finance. I even tried telling her to pay me a nominal amount every month as I am currently job less as well. However, again she cites helplessness, though she is paying 2 maids to keep the house clean and for taking care of a few cats at the house. Please help. thanks
