BuzzBuzzHome.com -Macklowe Properties condo project 737 Park Avenue is officially launching sales today, with two model units open for touring.

The 20-story pre-war conversion, located on the northeast corner of 71st Street, offers about 60 three- to six-bedroom homes ranging from 3,000 square feet to over 6,000 square feet. Pricing begins at $3.825 million and zooms to over $30 million — not a deterrent to buyers, since over 30 percent of the units are already in contract.
