Selling property owned by multiple owners

I built a home on a piece of property that my father put into my name and also my 2 siblings. My father wanted one of us close to him to help take care of him in his old age, which I did. He has since passed away and no one lives in his home, it needs a lot of work. I am the only one that lives on the property in the home that I built. The home that I built is separate property if I understand correctly. The problem now is I want to sell the home that I built and my 1/3 interest in the property but my 2 siblings do not want to sell. One sibling is offering to buy me out at a big discount price. How can I sell my home and my interest in the property without taking a big lose in value? Thank you for your response.
