Baird & Warner began in 1855 in Chicago as a real estate and mortgage business and grew through the city's rebuilding after the Great Fire and later housing expansion. The company now provides residential brokerage, home financing through Key Mortgage Services, title and closing services through Baird & Warner Title Services, and property management for rental homes, townhomes, condos, and small apartment buildings. Baird & Warner remains a family-owned real estate services company with a long presence in Chicagoland and a business model built around buying, selling, lending, title work, and rental property management.
