Aaron O'Toole has represented clients in connection with numerous multifamily rehabilitation projects involving the full range of affordable housing finance tools.  In addition to low-income housing tax credit and tax-exempt bond financing, he has been involved in the preservation of expiring use properties, the restructuring of troubled HUD-financed properties, and in public housing/mixed-finance developments.  Many of these projects have involved a mix of residential and commercial uses.  Aaron also represents nonprofit organizations utilizing New Markets Tax Credits to finance community development facilities such as charter schools and health centers.  A considerable part of Aaron's practice involves projects in the District of Columbia, and he is intimately familiar with the District's funding agencies as well as local laws governing cooperative and condominium conversion, rent stabilization, tenant purchases, tax exemptions, and general landlord/tenant issues.

Before joining Klein Hornig, Aaron served as Adjunct Faculty and Staff Attorney for the Georgetown University Law Center's Housing and Community Development Clinic (Harrison Institute for Public Law).  Prior to joining the Harrison Institute, Aaron practiced in the Real Estate and Litigation Departments of Wiggin & Dana in New Haven, CT, and clerked for Judge Lucero of the United States Court of Appeals for the Tenth Circuit.
