Probate Property Question

[Colton Sibley]

Recently came across a probate property that is essentially a duplex type of home. Located right next to a college. It is a SFH with a guest suite in the basement. It is joint tenancy with three sibling. Two of the siblings want out. I am friends with the other.

My questions is...Is there a way to buy them out legally? I know you can but how? while gaining equity to keep a cash flow mindset and partner with the 3rd sibling. 

As a bonus to this question...does any one have any good strategies for claiming a cash flow year around on a college property? It is also located 10 minutes from a thriving down town. 

Thanks for all the insight!
