<prompt> Human: I have 3 cards, a capital one venture card, amex blue cash preferred for gas and groceries, and a Target card used exclusively for Target. The thing is, I only have a 15k limit on the first two cards and have had a really tough time getting them to raise it. I have good credit over 700 and make a severe amount of money software developer in SV. I pay everything off 100 each month. How come I cant get a 25k or higher limit? I shouldnt have to max out the venture card anytime I take a nice vacation.  <response>: I have good credit over 700If its low 700s, thats not all that great. Humongous difference between, say, a score of 710 and a score of 780.Your income has surprisingly little to do with your credit rating. I havent even worked in well over a decade SAHM and have nearly an 800 score.Sometimes they will raise it if you ask. Sometimes you have to threaten to close the card. I have had limits raised by calling and asking how to close the card, and when they ask why saying it doesnt meet my needs because the limits are too low.
