thanks for 东南风起 and 小小石头's help, here is my understanding (if this is wrong, it must be I misunderstood them, not their fault):
Rental Operating Loss = Rent - (martgage/interest+repair+Ad+Fees) - Depreciation
If your AGI > 150k, you can't claim any loss, but you can carry over to next year to offset your future profit (if you get one).
==============================================================
Should you take depreciation if you AGI > 150k?
Someone say don't take it, because when you sell your house, the depreciation you took will be deducted from your cost, and make the profit larger. Since your AGI > 150k and you can NOT deducted it anyway, you might as well not taking it, so by the time you sell your house, your paper profit will be less, hence you pay less tax.
This trigger my question:
Should you take the depreciation ANYWAY, even though you can not deduct the depreciation? 
Somehow it seems like one should still do the depreciation, so you can accumulate more loss to offset future profit.
Yes the depreciation will be added back in when you sell the house, make the sell profit higher. But as long as the selling profit is 
Does this theory make sense, or not?

                    Unforunately, you have to depreciate the house. However
