We work with, and for, three main audiences: Government agencies, professional organizations such as financial institutions, insurance companies and real estate developers, and individuals, the people who buy and sell homes every day in the United States.

Our information is available in different formats for different audiences. For governments we normally engage directly to drive valuation and reassessment programs as a consulting organization. For corporations, we may act directly as a consultant or may execute a custom research commission or provide existing reports and research. For individuals we offer two free services, one currently for all individuals in New York State interested in accurate valuations, and another for individuals living within certain areas we have specifically reassessed.
