Heirs house and confusion

[Trellis Alexander]

So my family owns this house next to my mothers. It’s my dads grandma house he pays property taxes on it every year, it’s vacant. Him and his brother has had a few fall outs over the house because neither agree to come to mutual agreements with the house. My uncle doesn’t pay property taxes at all but he’s basically sabotaging the house and my dad pays the property taxes every year. I think all of my dads brothers and sisters names are on the deed including my crazy uncle. I want to start off with a multi Family home, but this house could be a great way to get my feet wet without all the hard money loans and private loan confusion. Cash flow would be great because the house is paid off for with some rehabbing that needs to be done. I stay in FLORIDA, is it a dead cause for me to be able to get this house without the headache my dad think it will be? How can I legally be able to get the house without having my dad terrified of my uncle going crazy on me or anyone of us?
