Montecito Medical Real Estate announced that it has acquired a three-building oncology medical outpatient building (MOB) portfolio in New York for an undisclosed price.
The MOB portfolio is located on New York’s Long Island and totals 72,638 square feet of rentable space. The buildings are located in Port Jefferson, Southampton and Research Ridge, New York. They are fully leased to New York Cancer & Blood Specialists, an oncology and hematology provider that operates more than 40 locations throughout New York City, Long Island and the Hudson Valley.
Montecito Medical specializes in healthcare-related real estate acquisitions and funding. Since 2006, it has completed transactions involving more than $6.5 billion in medical and veterinary real estate transactions.
“We’re proud to add these assets to our portfolio and to begin a long-term partnership with an outstanding medical group serving patients across New York,” said Rus Gudnyy, Senior Vice President of Investments at Montecito Medical.
“This acquisition represents our company’s entry onto Long Island, and we are excited to expand our nationwide footprint into this important market area,” said Chip Conk, CEO of Montecito Medical.
This marks Montecito Medical’s 17th transaction of the year. Since the beginning of the year, the company has purchased MOBs in Georgia, Florida, Indiana, South Carolina, Minnesota, Arizona, Ohio, California and New York for a total of 915,385 square feet.
According to data captured in the LevinPro HC database, this transaction represents the 100th MOB acquisition of 2025. There were 212 MOB transactions announced in 2024, and 199 announced in 2023. This is also the third MOB transaction announced in New York since the start of the year.
