How much is the take-home pay if you make $200k a year? About 12K a month? A rent of 5k would take away almost half of that. A $4K rent would be at the limit of the 1/3 recommendation but not sure what you can find these days for a $4K rent. It's doable, but I don't think it's sustainable if you want to save money or live comfortably
You can get very nice (NYC level nice) 1bd in a good spot easily for $4k. So a 30 year old professional working at bigcorp as a senior _____, they can afford it. I wouldn't want to pay that though. It's just 4k a month being thrown away to do the NYC thing. Good for 1 year if you're single, but after that it's like been there done that.
