Item 2.01. Completion of Acquisition or Disposition of Assets.

The Laurel Condominium

On September 5, 2014, American Realty Capital New York City REIT, Inc. (the “Company”), through its wholly-owned subsidiary, completed the acquisition of three commercial condominium units (together, the “Unit”) located at 400 East 67^th Street in the Upper East Side neighborhood of Manhattan. The seller of the Unit was USPF IV Laurel Retail Owner, L.P. (the “Seller”). The Seller has no material relationship with the Company, its operating partnership, its sponsor or advisor or any of their respective affiliates.

The contract purchase price for the Unit was $76.0 million, exclusive of closing costs. The Company funded the purchase price with proceeds from its ongoing initial public offering. The Company may seek financing for the Unit after closing from a lender yet to be identified. There is no assurance that the Company will be able to secure financing on terms that it deems favorable or at all.

The Unit contains 58,750 rentable square feet and is 100% leased to three tenants: Cornell University, which represents 58% of annualized cash base rent, TD Bank, N.A., which represents 23% of annualized cash base rent, and Quik Park East 67^th Street LLC (“Quik Park”), which represents 19% of annualized cash base rent, in each case based on leases in place at the time of acquisition.

The following table provides information relating to lease commencement and termination dates, rentable square feet, rental escalations, renewal options and annualized cash base rent for each of such three tenants:
