Investment Insights

Based on property information with market context.

150 Sixth Ave is a turn-of-the-century, four-story three-family brownstone with significant original character throughout. The home is currently configured with a ground-floor 1-bedroom garden apartment, a three-bedroom, 1.5-bath duplex on the parlor and 3rd floors, and a 2-bedroom apartment on the top floor. A large unfinished basement adds additional flexibility, while the interior features original doors, moldings, several marble fireplace mantels, plaster ceilings, and parquet hardwood floors. The property also includes a large rear yard with a mature cherry blossom tree.

Set up as a rare 22-foot-wide townhouse built 50 feet deep, the building totals approximately 4,400 square feet on a 22 x 100 lot. It is located on a tree-lined block in Park Slope, very close to Prospect Park, and near the shops and restaurants along 5th and 7th avenues. Transit access includes the B/Q trains at 7th Avenue and the 2/3 trains at Grand Army Plaza or Bergen St.

This configuration can work well for an owner-operator or investor seeking multiple residential units within a single property, supported by substantial interior detail and outdoor space. The large unfinished basement and the overall size of the townhouse provide room to tailor the layout to different living or operating needs, subject to applicable approvals.
