Credit line increase on credit cards

[Steve Sapowsky]

Obviously you shouldn't lie ;). That being said when requesting a credit line increase for a credit card and they ask for your annual income obviously the more the better, but what about monthly rent or mortgage is it better to give a lower number for that category? Also when they ask how much do you spend monthly with credit cards, is it better to report spending more or less? In other words what information would one need to provide on these specific topics in order to maximize the credit line increase?
