Buying siblings out to obtain an investment property

I have a question for you my parents deceased and left my siblings (five other children) a home that is paid off. I want to buy the siblings out, but I don't know what to do. Could you advise me on the best way to buy them out. it may be one of the sibling ,that might want to invest in the house as well. It's a nice home. Well taken care of but it does need need few cosmetic updates but it's in a location that's growing and thriving and it would be a great investment deal and I would love to keep the house if all possible as an investment property.
