13th Floor Investments

13th Floor Investments is a vertically integrated real estate investment and management company based in Miami, Florida. Through our family of real estate fund vehicles, we acquire real estate assets, either directly or indirectly, by investing at various levels of the capital stack. We seek to invest in real estate assets at a cost-advantageous basis and drive value through a focus on operations and cash-flow management. Critical to our success has been the ability to invest opportunistically and to assume the role of both investor and operator, across all asset classes and stages of the economic cycle. We have experience negotiating through and structuring around complex, special situations. In fact, we thrive in these situations and believe outsized returns can be realized with manageable risk through prudent due diligence and structuring. We have closed transactions involving financially constrained developers, complex joint ventures, special servicers, banks, and other financial institutions, acquiring fee simple real estate, performing and non-performing notes, bonds, and other real estate-related securities. Our ability to perform extensive due diligence on, understand, and appropriately structure complex, special situations gives us a significant competitive advantage.

Managing Principal

Arnaud Karsenti

Arnaud Karsenti is the Managing Principal of 13th Floor where his core focus is new business origination, risk evaluation, and financial structuring. Mr. Karsenti is primarily responsible for the general direction of the firm’s investment strategy and overall capitalization. In this capacity, Mr. Karsenti’s role is one of revenue generation and fund raising from investors and lenders. Mr. Karsenti has been active in the real estate business since 2003 when he began his real estate career assembling and developing land parcels in Miami’s urban cores. These initial one-off acquisitions led to the creation of 13th Floor as a fully vertically integrated real estate investment firm which has acquired and managed approximately $425 million in real asset value (projected total project cost) since inception. The consummated transactions have ranged between simple property acquisitions to restructuring of distressed debt, fractured residential inventory, community district development bonds, and a host of joint venture structures. In each case, Mr. Karsenti’s role is to first identify intrinsic value within the underlying property, and then determine the most optimal structure by which to acquire it. When faced with uncertainties and risk, Mr. Karsenti is well versed at pricing those risks and identifying the required business plan required to extract value made on the purchase. Prior to founding 13th Floor, Mr. Karsenti founded Collegeboxes, one of the nation’s leading college-based shipping and storage company. Originally the subject of an engineering class project, Collegeboxes grew to over 40 markets across the United States before being acquired in 2004. Today, the firm is owned by U-Haul and remains nationally recognized as one of the premiere solutions for college students across the country. Mr. Karsenti graduated cum laude from the Pratt School of Engineering at Duke University, with a degree in Mechanical Engineering, and holds an MBA from the Harvard Business School.
