Subsequent Events	Note 12. Subsequent Events *Acquisitions* USA SF Self Storage, DST Between January 22, 2014 and February 25, 2014, we through an indirect wholly-owned subsidiary, closed on the purchase of an additional approximately 86% in beneficial interests (the “SF Interests”) in USA SF Self Storage, DST (the “SF DST”), a Delaware Statutory Trust sponsored by our Sponsor, from approximately 45 third-party sellers pursuant to separate purchase agreements with each seller. None of the purchases were contingent upon any of the others. The agreed upon purchase price of the property relating to the SF Interests acquired was approximately $20 million. The acquisition brought our ownership of the SF DST to approximately 98%, including approximately 12% that we acquired previously in unrelated transactions. The consideration provided was primarily in the form of cash, an assumption of the pro rata debt of approximately $10.2 million and the issuance of approximately 245,000 limited partnership units in our Operating Partnership. We paid our Advisor approximately $0.2 million in acquisition fees in connection with these acquisitions. SF DST, owns a self storage facility located in San Francisco with an aggregate of approximately 1,120 units and 76,000 rentable square feet. SF DST leases its property to a master tenant (the “REIT I Tenant”) on a triple-net basis pursuant to a master lease (the “San Francisco Lease”) that had an original term of ten years and will expire on December 19, 2016. The REIT I Tenant is a wholly-owned subsidiary of us. Under the San Francisco Lease, the REIT I Tenant is required to pay a stated monthly rent equivalent to the monthly debt service payment under the loan, which is paid directly to the lender on behalf of the SF DST, a monthly stated rent, and certain annual bonus rent per the terms of the San Francisco Lease. As an Interest holder, we are entitled to our pro rata share of the total rent less the debt service under the loan. The loan had an aggregate principal balance of approximately $10.2 million as of January 1, 2014. The loan bears a fixed interest rate of 5.84%, and matures on January 1, 2017. The loan required monthly interest-only payments during the first five years of its term and now requires monthly principal-and-interest payments based on a 30-year amortization period. Hampton, VA On March 5, 2014, we through an indirect wholly-owned subsidiary, closed on the purchase of a self storage facility located in Hampton, Virginia for approximately $6.7 million.

We paid our Advisor an acquisition fee of approximately $0.1 million in connection with this acquisition. The facility has approximately 480 units and 51,000 rentable square feet. *Potential Acquisition* On March 13, 2014, we entered into a purchase and sale agreement for a parcel of land located in Toronto, Canada. The purchase price for the acquisition is $3.8 million Canadian dollars. We expect to close this acquisition by the end of the second quarter of 2014. There can be no assurance that we will complete such acquisition. In some circumstances, if we fail to complete such acquisition, we may forfeit some earnest money as a result. Our intent is to develop this parcel of land into a self storage facility with approximately 900 units and 80,000 rentable square feet. *Key Bank Revolver* Subsequent to December 31, 2013 the aggregate commitment under our KeyBank Revolver was increased from $75 million to $100 million and two additional financial institutions became participating lenders. *Declaration of Dividends* On March 20, 2014, our board of directors declared a distribution rate for the second quarter of 2014 of $0.001917808 per day per share on the outstanding shares of common stock payable to stockholders of record of such shares as shown on our books at the close of business on each day during the period, commencing on April 1, 2014 and continuing on each day thereafter through and including June 30, 2014. *Distribution Reinvestment Plan* As of March 21, 2014, we have issued approximately 0.9 million shares of our common stock for gross proceeds of approximately $9 million under our DRP Offering.

The receipt of the distribution by the advisors to REIT I and REIT II is subordinate to return of capital to the original REIT I and REIT II stockholders plus at least a 7% cumulative, non-compounded return, and such advisors’ share of the distribution is 15%.
