Forcing a property/business owner to change a material part of the approval process in an attempt to additionally "accommodate" source of income recipients is contrary to the rationale of a reasonable accommodation.  Individuals that do not qualify without Section 8 funds/HCV is discriminatory in this light.  The rental and housing policies need to be fairly distributed and bring an sense equality to everyone.  This sort of hand-tying property owners will likely be used to push other modifications of a similar nature, such as adjusting deposits, acceptance of poor rental history, poor credit worthiness, and dangerous criminal history to meet the agendas of individuals or groups who may not be stakeholders.  It is these bureaucratic agendas that are of concern to property owners and upsets the free enterprise system.  This is at the heart of the reasoning that many property owners shy away from these governmental programs.
