Congrats on CLI
I see that you ask for a porportionately small amount when requesting a CLI with AMEX. Any particular reason? The nerds are in consensus when it comes to AMEX. They say to ask for 3x your current limit and at worst, it will end up doubled.
On the contrary, if the CLI seems too big, that is only because you see it as an enticement, I would submit. That is to say, a 50k line will certainly help maintain with ease, a very respectable debt to credit ratio. That UTIL excellence will be shining when you go to buy something big or invest one day. Take the 50k and enjoy it. Just...don't spend it! ✌️😀
