After Louise Machinist, Jean McQuillen and Karen Bush met at church, they turned their friendship into a new lifestyle that allowed them to save money while creating a community. With legal and financial advice guiding the divorced women, they bought a five-bedroom colonial in Mt. Lebanon, Pennsylvania. All three names are on the mortgage, they split their household expenses, and they obey a list of agreed-upon rules that includes no overnight guests for more than seven days. While they’ve managed to save more money by sharing a home for the past nine years, they also enjoy the benefits that come from sharing their lives.
