Real Estate


Mr. Mantell has extensive experience in virtually every facet of the real estate industry. He oversaw development activity for a national real estate brokerage firm. He ran his own vertically integrated company that developed more than 5,000 apartments and owned office, retail, and hotel properties around the United States. That company was the property manager of the properties it owned. Mr. Mantell also has extensive experience in real estate finance. He founded a national multi-family lender and headed the commercial mortgage-backed securities division of a global investment bank. In addition, with respect to distressed debt, Mr. Mantell has renegotiated hundreds of millions in loans with dozens of financial institutions, and oversaw debt management regarding the multi-billion dollar non-performing commercial mortgage portfolio of an international bank.

Today, Mantell Advisory consults to real estate owners and developers involved in complex situations across the U.S. Whether replacing a global financial institution acting as the asset manager of a multi-block development site in mid-Manhattan, guiding the re-zoning and development of a high-rise project in the Washington D.C. metro area, or assuming temporary control of the operations of a business owning and developing dozens of shopping centers around the US, our knowledge and creativity add value for our clients.
