David Dental, DDS, and his unmarried partner, Sally Surgeon, MD, have lived together for the past 5 years. Both are at the peak of their careers and decide to buy a new "show case" home in La Jolla, California. After looking at several homes in the area, they buy one for $2 million. They put a 20 percent down payment ($400,000) on the house and financed the balance ($1.6 million). Each takes out a separate mortgage for $800,000 for a total of $1.6 million. There is no debt (e.g., a home equity loan) on the residence.
