The house is worth alot more now than when first purchased--she is unemployed--and sell it --cash enough to buy something outright-and put $$ aside for kids.
People can lose their minds when it comes to money---I know of a young boy that inherited $50, 000 from his father's life insurance policy. A few of his uncles lined up to take him in--------just b/c they thought they would get some of that money.
I have a feeling that house was totally remodeled (inside too). Possibly, the previous owners did some work, but it looks very Italian in contrast to the other homes (IM's influence and taste?). Possibly, the facade was changed too, by the Mayers. The original value of the home was probably a lot less, because there has been major renovations since. Although, the back and forth of selling the home within the family circle was probably ways to get cash out of the house. In my experience, refinancing, adding or subtracting a spouse to or from the deed only requires a one dollar sale for the booksnot the entire value of the house. JMO
