A benefit-cost analysis of New York State's Limited Profit (Mitchell-Lama) housing program as it has operated in New York City. Both city and state agencies supply long-term, low-interest mortgage funds to private developers of middle-income housing. From a study of 123 projects, general findings are that net tenant benefits amount to $695 annually per household on average. Neighborhoods in which projects are located have increased their assessed valuation annually by 9.89 percent, whereas control areas increased only 4.64 percent. The findings lead to two policy recommendations: locate future projects in medium quality areas; and focus on serving middle-income families with children by revising admission standards, providing more two- and three-bedroom units, and exercising more control over eligibility of families after their admission to the program.
