My mother owned a home in FL and listed my uncle as a tenant in common. She passed away last year w/o a will. So basically my uncle is listed as the first owner and the estate is the second owner. My uncle is willing to let me buy out his share of the home for the amount he put into it. I am currently in the process of becoming the estates personal representative, but I need to know how to get my name on the deed since I cannot make any changes (i.e. homeowner's insurance, re-fi). Any suggestions as to how I should proceed. Unfortunately, I do not have expendable cash.

If you become the personal representative you can make any changes that have to be done to the insurance and the such.

Who ever will inherit the estate will inherit and the probate judge will issue a order to do a new deed adding the person who inherits to the deed.

So when you legally inherit from the esate you get your name added.
