Selling Xbox One X, question

Hey all. Im looking to sell my Xbox One X and I'd like to sell it with the gold membership I still have left and the downloaded games I have on it.Is there a way to do this? If not does anyone recommend using a site like playerauctions to sell my xbox account first before selling the actual console? Im a bit worried that if I do the 2nd option that my credit card details might be able to be found on my account somehow?

I have about 10 months membership left and about 3 or 4 games on the account so I don't really want to wipe that before selling the console.

Thank you

You definately need to go to your account settings on the ms page, and remove the payment option.
