NEW YORK CITY—Gramercy Property Trust Inc.  said Tuesday afternoon that it has agreed to buy a dozen single-tenant net lease properties from Dividend Capital Diversified Property Fund Inc. for approximately $399 million, including the assumption of $142 million of existing secured debt. Spanning the office, industrial and data center asset classes, the 2.67-million-square-foot portfolio is located mainly in the Los Angeles and Dallas suburbs, with other properties in Houston, the Denver and Miami metro areas, Illinois, Ohio and Northern New Jersey.

GPT says the portfolio is 100% leased, with a weighted-average lease term of about 6.7 years. That average will be bumped up to eight years if DPF's current negotiations to extend and restructure two of the leases are successful.

In an SEC filing Wednesday, GPT identified the properties in the DPF portfolio. A data center at 1920 E. Maple Ave. in El Segundo, CA is the highest-priced of the 12 assets at $58.2 million. There are three other Southern California properties in the portfolio: 3701 Doolittle Dr. in Redondo Beach; 5200 Sheila St. in Commerce; and 2000 Corporate Center Dr. in Thousand Oaks.

There are three Texas assets in the portfolio: 6000 Connection Dr. in Irving and 1460 N. Glenville Dr. in Richardson, both suburbs of Dallas; and 15350, 15355, 15370 and 15390 Vickery Dr. in Houston. Rounding out the portfolio are 6 Sylvan Way In Parsippany, NJ; 1600-1601 SW 80th St. in Plantation, FL; 3201 Columbia Rd. in Richfield; OH; 200 Corporate Dr. in Dixon, IL; and 18300 E. 28th Ave. in Aurora, CO.

In connection with the planned acquisition, GPT has launched an offering of 45 million shares of common stock, with a 30-day option for the underwriters to buy up to 6.75 million additional shares. Morgan Stanley, BofA Merrill Lynch, J.P. Morgan and RBC Capital Markets are acting as joint book-running managers for the offering, which will be used partly to help fund the $257-million cash portion of the DPF portfolio sale and partly to help fund the acquisition of 10 other properties GPT has under contract.

Separately, GPT said last week it had closed on the all-cash acquisition of four industrial properties in four separate transactions totaling $35.5 million. They total 560,000 square feet and include a 109,000-square-foot manufacturing facility in Puyallup, WA; a 240,000-square-foot warehouse in Groveport, OH; a 117,000-square-foot light industrial property in Lewisville, TX; and a 94,000-square-foot headquarters and warehouse in Rolling Meadows, IL.
