How much to lower the asking rent to generate more response?

[Johann Jells]

I'm not getting much response at $1890. Departing tenant was paying $1770 and HUD said 2br here went up about $200 in 2 years so I went for it. Now the question is how low should I go to get interest. Does $100 make a lot of difference? My gut says no but people are funny. Arithmetic shows it's not worth losing a month for another $100. Thoughts?
