Kushner has experienced immense growth and dynamic accomplishments in 2018. With more than $4.34 billion in transactions, we have expanded our multifamily portfolio, launched a hotel division, increased our lending platform, and grown our network of partners and lenders.
We successfully closed a $200 million refinancing for 65 Bay Street, a 447-unit luxury tower in Jersey City, and $500 million of financing for newly acquired multifamily units. As a result of leasing more than 95% of the 750,000 square feet at Dumbo Heights in Brooklyn, we closed a $480 million financing with our partner RFR.
Our hospitality development and management platform is led by two executives who are well-respected in the industry. We are now operating six hotels, two of which are ground-up developments. We are excited to penetrate different markets with hotels such as Rivington in the Lower East Side of Manhattan, Princeton Marriott at Forrestal in New Jersey, and Bungalow in Long Branch, New Jersey.
Kushner continues to aspire to be the best developer, partner, operator, and lender in the industry. Our mission is to provide our tenants with productive, efficient, and state-of-the-art environments. Investment decisions are based on our successful experiences in the past, and more importantly, our vision for the future.
