Inwood is a neighborhood in the New York City borough of Manhattan, at the northern tip of Manhattan Island, in the U.S. state of New York. Inwood was a very rural section of Manhattan well into the early 20th century. Once the New York City Subway's IRT Broadway–Seventh Avenue Line, the modern 1 train, reached Inwood in 1906, speculative developers constructed numerous apartment buildings on the east side of Broadway. Construction continued into the 1930s, when the IND Eighth Avenue Line, the modern A train, reached Dyckman and 207th Streets along Broadway and the large estates west of Broadway (Seaman, Dyckman, Isham, etc.) were sold off and developed. Many of Inwood's impressive Art Deco apartment buildings were constructed during this period.

Inwood's real estate rents and values are sharply bifurcated between east and west. According to Manhattan Community Board 12, the districts east of Broadway are predominantly lower-income. This area is also more industrial and commercial and has fewer parks and street trees. Real estate values and rents are correspondingly lower than the area west of Broadway. Almost all of Inwood's co-ops and all of the private houses are located on the west side of Broadway.
