Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

As reported earlier, on August 14, 2014, Strategic Storage Trust II, Inc. (the “Registrant”), through 26 wholly-owned subsidiaries of its operating partnership, Strategic Storage Operating Partnership II, L.P. (the “Operating Partnership”), executed 26 partial assignments of the purchase and sale agreement originally executed by a subsidiary of the Registrant’s sponsor on July 9, 2014, with unaffiliated third parties (the “26 Property Purchase Agreement”) for the acquisition of a portfolio of 26 self storage facilities (the “26 Property Portfolio”). The 26 Property Portfolio consists of 14 self storage facilities located in California; four self storage facilities located in Michigan; three self storage facilities located in Colorado; two self storage facilities located in Illinois and one self storage facility located in each of New Jersey, Washington and Maryland. The aggregate purchase price for the 26 Property Portfolio is approximately $128.2 million, plus closing costs and acquisition fees. As reported earlier, on January 23, 2015, the Registrant closed on the purchase of the first phase (the “First Phase”) of the 26 Property Portfolio which consisted of seven self storage facilities for approximately $25.9 million, plus closing costs and acquisition fees.

On January 29, 2015, the Registrant closed on five self storage facilities located in California and Colorado representing the second phase (the “Second Phase”) of the acquisition of the 26 Property Portfolio for a purchase price of approximately $28.4 million, plus closing costs and acquisition fees, which was funded with a combination of proceeds from an issuance of Series A Cumulative Redeemable Preferred Units (the “Preferred Units”) in the Operating Partnership, as described further below, and a draw of approximately $16.4 million under the KeyBank Facility, as described further below. The Registrant incurred acquisition fees of approximately $496,000 in connection with the Second Phase of the acquisition of the 26 Property Portfolio. The five properties acquired in the Second Phase consist of approximately 3,420 units and approximately 332,600 net rentable square feet of storage space. The average physical occupancy of the five properties acquired in the Second Phase was approximately 86% as of December 31, 2014.

On January 21, 2015, SSTI Preferred Investor, LLC (the “SSTI Preferred Investor”) invested approximately $24.1 million in the Operating Partnership (the “Preferred Equity Investment”) and the SSTI Preferred Investor received approximately 960,000 Preferred Units in the Operating Partnership. The Registrant used approximately $12.0 million of the proceeds from the Preferred Equity Investment in connection with the acquisition of the Second Phase of the 26 Property Portfolio, approximately $10.6 million in proceeds in connection with the closing of the First Phase of the 26 Property Portfolio and the remaining $1.5 million in proceeds will be used in connection with closing the remaining phases of the 26 Property Portfolio. The issuance of the Preferred Units are governed by the Series A Cumulative Redeemable Preferred Unit Purchase Agreement and Amendment No. 1 to the Second Amended and Restated Agreement of Limited Partnership of the Operating Partnership, each as described earlier in the Form 8-K filed by the Registrant on November 6, 2014.

In order to finance a portion of the Second Phase of the 26 Property Portfolio, the Registrant borrowed approximately $16.4 million under the KeyBank Facility. The KeyBank Facility and the terms of the KeyBank Credit Agreement are described in the Form 8-K filed by the Registrant on January 26, 2015. The amount drawn was in the form of a Eurodollar Loan under the KeyBank Credit Agreement which will bear interest at approximately 3.4%. Pursuant to joinder agreements by the five special purpose entities wholly-owned by the Operating Partnership (the “Property SPEs”) in favor of KeyBank as administrative agent, the five properties acquired under the Second Phase now serve as additional collateral under the KeyBank Credit Agreement and the Property SPEs now serve as additional borrowers.

A summary of the properties acquired in the Second Phase of the 26 Property Portfolio is as follows:

Strategic Storage Property Management II, LLC, an indirect subsidiary of SmartStop Self Storage, Inc., the sponsor of the Registrant, will manage the five properties acquired in the Second Phase of the 26 Property Portfolio and will be paid a one-time fee of $3,750 for each of the five properties. In addition, Strategic Storage Property Management II, LLC will be paid management fees in an amount equal to 6% of the gross monthly revenues collected from the five properties.

The Registrant expects the acquisitions of the remaining 14 properties of the 26 Property Portfolio to close in additional phases over the next few weeks. The Registrant expects to fund the additional phases of the 26 Property Portfolio with a combination of proceeds from the Preferred Equity Investment, additional issuances of Preferred Units and additional draws under the KeyBank Facility.

Since it is impracticable to provide the required financial statements for the acquired real property described in Item 2.01 at the time of this filing and no financials (audited or unaudited) are available at this time, the Registrant hereby confirms that it intends to file the required financial statements on or before April 16, 2015 by amendment to this Form 8-K.
