Meet Gravity Realty Group

Jack Baum has built his commercial real estate practice the old-fashioned way — by knowing the streets. As Principal Broker of Gravity Realty Group and an affiliate of Link Brokerages, Jack specializes in landlord representation, retail leasing, and multifamily investment sales across Manhattan and Brooklyn with a hands-on, direct-to-client approach that sets him apart in one of the world's most competitive commercial markets. His expertise spans the full commercial transaction lifecycle — from matching business operators with the right retail storefronts to facilitating complex multifamily investment sales and securing long-term tenants for building owners looking to maximize their property value. What defines Jack's practice is street-level knowledge and disciplined follow-through — physically scouting New York's commercial corridors, maintaining direct relationships with property owners, and keeping transactions moving with the focused attention that complex commercial deals demand.
