(Portland, OR)  --  A new tax deal would use tourism money to help house homeless people.  City officials along with Multnomah County and Metro leaders are working on the agreement to expand the use of the two-point-five percent tax on rental cars and hotel rooms.  It's been used to fund the Oregon Convention expansion, but could now be put toward the Joint Office of Homeless Service.  If it moves forward, over five-million-dollars a year would be going toward the homelessness problem in Portland.
