National Realty Investment Advisors

National Asset Services (NAS) is a U.S.-based commercial real-estate asset and property management firm. Founded in 2008, NAS specializes in managing a broad and diversified portfolio of commercial real estate — including office, retail, medical office, industrial / flex, multifamily, student housing, senior housing, and mixed-use properties.

NAS focuses on maximizing value for property owners — they position themselves not just as passive managers, but as active asset-managers who apply strategic leasing, cost optimization, capital improvements, and proactive operational oversight. The goal is to enhance cash flow, stabilize occupancy, and increase long-term value for investors and owners.

Because of their breadth and longevity, NAS offers property owners and investors a “turn-key” solution for managing commercial real-estate assets across many markets — often stepping in when properties are underperforming or need repositioning, refinancing, or recapitalization. Their claim: a track record of delivering hundreds of millions in distributions and managing multi-billion-dollar portfolios over time.
