Career
Nail got his start in the real estate business working for Philip A. Payton, Junior."s Afro-American Realty Company, another real estate firm catering to African-American customers in New York City. In 1905, he founded the Nail-Parker Company with Henry G. Parker. Starting in the late nineteenth century, African Americans began moving from the southern United States into the New York City area.
Nail realized that most of these new arrivals were not financially able to purchase homes, and began converting or constructing apartments on his land purchases.
By 1925, Nail"s business owned around fifty apartment buildings in the Harlem area. Nail became the most important Black real estate agent in New York City, and sat on the Real Estate Board of New York and the Housing Committee of New New York
In each case he was the only African-American member. After the Great Depression struck, Nail"s business went bankrupt in 1933.
Nail attempted to restart successor businesses but was unable to get them off the ground.
Nail died in 1947. His work left Harlem a community of renters rather than owners, and led ultimately to the area being populated by working-class tenements.
