Do I have to file non resident Idaho return?

I have lived fulltime in CA, but I have a rental property in Idaho.  The rental property is reporting a net loss on the federal return.  Gross income is over $2500 for the ID rental income but after including expenses the net income in negative.  Do I have to file an ID non resident return and if so would I report the full gross rental income and then get credit for the tax paid to ID on my resident CA return?
