Margery Spinney and Carol Smith founded Renting Partnerships to expand opportunities for people who need affordable housing to participate meaningfully in management and build financial assets. While she was the Director of the Cornerstone-Homesource Regional Loan Fund, Margery worked with the Franciscan Friars and Women's Research and Development Corporation to establish housing that would "give hope to people who are left out of ownership." At the time, Cornerstone was a nonprofit community development loan fund which had helped fund many nonprofit groups provide affordable housing. Carol helped to manage the loan fund and later became the administrator for this and two subsequent "renter equity" projects. Residents' incomes averaged about $20,000. However, over 10 years they built over $140,000 in equity credits and earned a reputation as an oasis in a neighborhood otherwise known for its crime and social problems. Cornerstone changed its name to the Cornerstone Corporation for Shared Equity. A third party evaluation of Renter Equity at Cornerstone was funded by the Ohio Housing Finance Agency and conducted by the Corporation for Enterprise Development in 2012. The study found:
- "Positive impact on residents' lives in terms of their physical and financial security, their optimism about the future and their ties with their surrounding community."
- "Property management costs similar to comparable Low-Income Housing Tax Credit properties in the neighborhood, even after taking into account the renter equity credit costs."
- "A majority of residents stay five or more years."
