Kips Bay may not be the most trendy ‘hood, but it’s just a few blocks away from bustling Nomad, all the bars in Murray Hill (if that’s your thing) and a quick walk to Grand Central. And as of today, 18 units are up for grabs through the city’s affordable housing lottery at 145 Madison Avenue, a new 21-story rental building between East 31st and 32nd Streets. The mixed-income units are reserved for those earning 30, 60, and 120 percent of the area median income and range from $580/month studios to $2,270/month one-bedrooms.
