House inheritance through probate

[Kevin Vasquez]

Hey guys!

So my grandma passed away and her home was spilt into 4 shares between my mother and her 3 siblings. None of the siblings communicate with each other nor seem to have a vested interest in the home. My mother lives in Florida and would like to acquire the home fully for rental purposes. She has been paying the property taxes through her own funds since my grandmothers passing 4 years ago.

#1: Since my mother is a partial owner can she legally rent this home out? 

--- Even considering going the month to month route for a tenant----

#2: Does she have any legal advantage since she has been paying the taxes out of pocket to avoid liens?

#3: If she wanted to transfer her share to me what is the process and do the other siblings have to agree?

Any advice and recommendations would be helpful
