Nature of Operations [Text Block]	ORGANIZATION General Except where the context suggests otherwise, the terms “we,” “us,” “our” and the “Company” refer to Jones Lang LaSalle Income Property Trust, Inc. The terms “Advisor” and “LaSalle” refer to LaSalle Investment Management, Inc. Jones Lang LaSalle Income Property Trust, Inc. is an externally managed, non-listed, daily valuation perpetual-life real estate investment trust ("REIT") that owns and manages a diversified portfolio of office, retail, industrial and apartment properties located primarily in the United States. We expect over time that our real estate portfolio will be further diversified on a global basis through the acquisition of additional properties outside of the United States and will be complemented by investments in real estate-related debt and securities. We were originally incorporated on May 28, 2004 under the laws of the State of Maryland. We believe that we have operated in such a manner to qualify to be taxed as a REIT for federal income tax purposes commencing with the taxable year ended December 31, 2004, when we first elected REIT status. As of December 31, 2012, we owned (i) interests in a total of 32 consolidated properties located in nine states and one in Canada and (ii) an interest in one unconsolidated property located in the United States. From our inception to October 1, 2012, we raised proceeds through private offerings of shares of our undesignated common stock. On October 1, 2012, the Securities and Exchange Commission (the “SEC”) declared effective our Registration Statement on Form S-11 (Commission File No. 333-177963) (the "Registration Statement") with respect to our continuous public Offering of up to $3,000,000 in any combination of Class A and Class M shares of common stock (the "Offering"). In order to facilitate the Offering, on September 27, 2012, with the approval of our stockholders, we amended and restated our charter to, among other things, (i) designate our outstanding common stock as Class E common stock, (ii) create two new classes of Class A and Class M common stock and (iii) make certain additional changes requested by state securities administrators. We also amended and restated our bylaws on September 27, 2012 in connection with the Registration Statement being declared effective by the SEC. Additionally, on October 1, 2012, we effected a stock dividend for all Class E shares at a ratio of 4.786-to-1 in order to achieve a Net Asset Value ("NAV") per share for each of the Class A, Class M and Class E shares of $10.00 as of the date we commenced the Offering. Affiliates of our sponsor, Jones Lang LaSalle Incorporated ("Jones Lang LaSalle" or our "Sponsor"), have invested an aggregate of $60,200 through purchases of shares of our Class E common stock. As of December 31, 2012, 26,444,843 shares of Class E common stock, 3,612,169, shares of Class A common stock, and 104,282 shares of Class M common stock were outstanding and held by a total of 1,949 stockholders. Prior to November 14, 2011, the Company (previously named Excelsior LaSalle Property Fund, Inc.) was managed by Bank of America Capital Advisors LLC (the “Former Manager”), a registered investment adviser with the SEC, that had the day-to-day responsibility for our management and administration pursuant to a management agreement between the Company and the Former Manager (the “Management Agreement”). On November 14, 2011, the Former Manager assigned its right, duties and obligations as manager of the Company under the Management Agreement to LaSalle and since that date, the Former Manager has had no responsibility for the management of the Company. LaSalle acts as our advisor pursuant to the amended and restated advisory agreement between the Company and LaSalle, which became effective on October 1, 2012 (the “Advisory Agreement”). Our Advisor, a registered investment adviser with the SEC, has broad discretion with respect to our investment decisions and is responsible for selecting our investments and for managing our investment portfolio pursuant to the terms of the Advisory Agreement. LaSalle is a wholly owned, but operationally independent subsidiary of Jones Lang LaSalle, a New York Stock Exchange-listed real estate services and money management firm. We have no employees as all operations are managed by our Advisor. We have certain executive officers, but they are employees of and compensated by our Advisor.
