John MacAffer

John MacAffer serves as a Broker at the PBS R00 Center for Broker Services within the General Services Administration’s Public Buildings Service, where he facilitates the acquisition and leasing of nonresidential commercial real estate to support federal agency workspace requirements. In this role, he acts as a critical liaison between federal stakeholders and property owners, managing end-to-end leasing transactions for office and operational facilities across the United States. His procurement activities center on securing long-term, cost-effective real estate solutions aligned with federal footprint optimization goals, utilizing lease instruments under GSA’s authority to meet agency space needs without capital investment. MacAffer maintains consistent working relationships with a select group of commercial real estate entities, including TWO CON LLC, ONNI TIMES SQUARE LP, CVD MAIN LLC, BELTSVILLE GSA FDA LLC, and CC OWNER LLC. These partnerships reflect a focus on experienced property owners and institutional landlords with portfolios of Class A and B office buildings in high-demand federal corridors. His contracting approach emphasizes direct negotiations and streamlined lease execution, prioritizing efficiency and compliance with federal real property regulations over competitive bidding for routine space acquisitions. His procurement pattern shows no use of socioeconomic set-asides, with 100% of actions conducted under full and open competition. This reflects a strategic preference for maximizing market access and leveraging the broadest possible pool of commercial landlords to achieve optimal value and location alignment for federal tenants, rather than targeting specific small business categories. MacAffer’s expertise is narrowly focused on NAICS 531120—Lessors of Nonresidential Buildings (except Miniwarehouses)—which encompasses the leasing of office, retail, and mixed-use commercial properties. He specializes in negotiating ground leases, build-to-suit arrangements, and tenant improvement allowances, demonstrating deep familiarity with real estate due diligence, space planning, and federal lease compliance standards under 41 CFR Part 102-80. His domain expertise lies in translating federal space requirements into binding real estate instruments that meet operational, security, and fiscal mandates.
