<prompt> Human: Pretty much what the post said. I know theres some sort of rule like dont pay over 13 of your salary on rent each month or something, just trying to see if people know it off the top of their head. I plan on trying to put as much in my 401K as I can early on I think around 10 so idk if that factors into the decision as well. Thanks!  <response>: The rule of thumb is 30. But that can swing wildly depending on all the other factors in your life: Do you eat out a lot maybe spend less on rent Do you not have a commute so you can spend more on rent Do you have roommatesAnd so forth
