NEW YORK CITY-Carlton Advisory Services arranged two simultaneous mortgage transactions aggregating $718 million on behalf of the Sapir Organization: $515 million of fixed-rate financing for Sapir's acquisition of 11 Madison Ave. concurrently with $203 million of floating-rate financing for 260-261 Madison Ave.

Eleven Madison is a 2.3-million-sf, class A, 29-story Midtown tower that serves as the world headquarters for Credit Suisse First Boston, which leases in excess of 85% of the building. Sapir purchased the building last month for $675 million from MetLife.

The other properties, 260-261 Madison, are two prime office assets facing one another in Midtown Manhattan that contain an aggregate of 900,000 sf of office and retail space. The properties are occupied primarily by long-term, credit and national tenants. Zar Realty is the asset and property manager of 260-261 Madison.
