Investment Insights

Based on property information with market context.

Brick two-family duplex spanning well over 2,000 square feet, with separate living arrangements on the top floor and lower level. The upper unit includes two bedrooms with a living and dining area, kitchen with a pantry, a full bath, main bedroom with two closets, and access to a private backyard. The lower level provides two additional bedrooms and a bath, plus a dedicated laundry area and boiler room.

Located in Bedford-Stuyvesant, the property is described as minutes from Manhattan with nearby J/M/Z lines. Walk and transit scores are listed as very strong (walkScore 82 and transitScore 84), and bikeScore is listed as 70. The remarks also note a gated driveway directly in front of the property to help avoid alternate side parking challenges. Broadway is referenced as the street across from the property where Bushwick begins.

This configuration can suit owner-occupants seeking additional income from the second unit or buyers looking for a residential income setup in a transit-accessible area. The private backyard access from the upper level, along with on-site laundry and off-street parking through the gated driveway, adds everyday practicality for both tenants and operators.
