Bradley T. Borden (Washburn) has published Financing Reverse Exchanges and Safeguarding Exchange Proceeds, 22 J. Tax'n Fin. Inst. 33 (Sept./Oct. 2008).  Here is the abstract:

Over the last several years, reverse exchanges have become a fixture of section 1031. A fluid economy and a strained financial industry send a reminder that safe guarding exchange proceeds in reverse exchanges is paramount. This Article reviews reverse exchange structures, both safe harbor and non-safe harbor, and describes how such transactions must be financed to satisfy tax law requirements and safe guard exchange proceeds. The Article is adapted, with permission, from Chapter 5 of Tax-Free Like-Kind Exchanges.
