Description

A prewar two-bedroom in the heart of Williamsburg, priced to move. Built in 1910, 407 Keap Street has held its corner of Williamsburg for more than a century: six stories of solid prewar brick that newer buildings spend decades trying to imitate. Unit No. 5 is a genuine two-bedroom co-op, generously proportioned in the way prewar apartments are and increasingly rare in this pocket of Brooklyn. Oversized windows pull in the light. The layout gives you two real bedrooms, not a one-bedroom asking to be more. Offered as-is: honest bones, and room to make it your own. Maintenance runs $521 a month, taxes included, one of the lowest carrying costs in Williamsburg for a home this size. As an HDFC co-op, it keeps ownership attainable for income-qualified buyers and the building's character intact. The location does the rest. You are moments from the Marcy Avenue subway, the Williamsburg Bridge, and the restaurants and storefronts that made this neighborhood a destination. At this price, this is prewar Williamsburg on terms that rarely surface: a true two-bedroom, a monthly cost that leaves room to live, and a building with a hundred years of standing behind it. Private viewings are booking now. Serious, income-qualified buyers: reach out to the listing agent to schedule a showing before it's gone.
