Transferred all my points (~20k) to AS. I don't spend on this card other than the first of the month because I put dining on CSR. Will hit Silver by EOY.

Let's say that you hit 50k points from rent alone and don't really spend on the card otherwise. Then you're at Silver. (Rent is capped at 100k points per year which isn't enough for Gold.) By the qualifying points method you need 75k more points to hit Gold and 150k more points to hit Platinum, which is (if you can't consistently use rent day promos) 25k / 50k on dining.
But you can just organically hit Gold/Plat by spending the same amount (not just on dining) with nothing on rent. VFTW says he hits Plat with card spend on the Rent Day promotions, hmm...
