Some suggestions you may consider.
If some characters are rich with gold, they can spend hundred if not thousand to relocate their homes.
I do agree current Family Home looks a little bland. You have an uncle who you dislike but get along after sometime.
Probably the only useful thing I ever had my character doing is having his realm fight another realm over a Family Home region that he wanted to be in his realm hand. Some silly war to fight over. It gets my creativity going. Family home region in someone else realm hand? Go fight for it
