Frugal siblings catch heat when their sisters get jealous, especially when it comes to family inheritance disputes. 

Likewise, when this young woman, the most financially savvy of the family, was in her early 20s, she invested in a house that she and her mother could share together as roommates. After living with one another for 5 years, she moved in with her husband, continuing to rent to Mom until her final days. 

But now the siblings want «their cut» of the house their mom lived in, despite the house being 100% owned by Lil Sis.
