Note. Schedules filed in paper format shall include a signed original and five copies of the schedule, including all exhibits. See Rule 13d-7 for other parties to whom copies are to be sent.

The information required on the remainder of this cover page shall not be deemed to be “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934 (the “Act”) or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

This statement constitutes Amendment No.7 (“Amendment No.7”) to the statement on Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) by Jonathan Garfield (the “Reporting Person”) in connection with the ownership of Common Stock, par value $0.02 per share (the “Common Stock”), of Reis, Inc., a Maryland corporation (the “Company”), with its principal executive offices at 530 Fifth Avenue, New York, NY 10036, as such Schedule 13D has previously been amended and supplemented (the “Schedule 13D”).

In accordance with Act Rule 13d-2, this Amendment No.7 amends and supplements only information that has materially changed since the December 3, 2014 filing by the Reporting Person of Amendment No.6 to the Schedule 13D (“Amendment No.6”). To the best knowledge of the Reporting Person, there has been no material change in the information set forth in response to Items 1, 2 and 7 of the Schedule 13D. Accordingly, those Items are omitted from this Amendment No.6. Unless otherwise stated, the information set forth in the Schedule 13D remains accurate in all material respects. Unless otherwise defined herein, capitalized terms herein shall have the meanings set forth in the Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration.

The matters set forth in Item 4 below are incorporated in this Item 3 by reference as if fully set forth herein.

On February 10, 2015, the Reporting Person received 14,894 shares of restricted stock units (“RSUs”).

On February 11, 2015, the Reporting Person received 3,663 shares of Common Stock upon vesting of RSUs. The Reporting Person was entitled to receive an aggregate of 6,435 shares of Common Stock but elected to relinquish an aggregate of 2,772 shares, which were cancelled by the Company in exchange for the Company’s agreement to pay federal and state tax withholding obligations of the Reporting Person resulting from the vesting and delivery of the RSUs.

The Reporting Person was entitled to receive an aggregate of 10,780 shares of Common Stock but elected to relinquish an aggregate of 4,444 shares, which were cancelled by the Company in exchange for the Company’s agreement to pay federal and state tax withholding obligations of the Reporting Person resulting from the vesting and delivery of the RSUs.

On November 10, 2015, the Reporting Person entered into a Rule 10b5-1 trading plan with B. Riley & Co., LLC for the purpose of selling up to an aggregate of 150,000 shares of Common Stock from November 10, 2015 through May 6, 2016 for the purpose of obtaining a degree of financial diversification.
