I’m going through the process right now in Kansas City Missouri and it seems like it varies from place to place. Leasing agencies seem to be the worst. One of these required everything you mention above except the passport scan, and it was 1.5 months of paycheck stubs from your employer.
I’ve found that if you hold the cat in your lap, use the finger and thumb of one hand to wiggle on either side of their face where their mouth begins to open their mouth, if you can then get the pill on the very furthest part of their tongue closest to their throat, there is an automatic reflex to swallow. I used to try putting it in their food and it never worked. This worked every time.
