Opening New Credit Lines

Hello All,

I asked this in a reply to another post, but thought I would post as a new question in the correct category.

So, I currently have 2 Cap1 cards. I was just approved for a mortgage, and will be closing in April (house is being built).

My question is, should I wait until 6 months after I close to open new accounts, or SHOULD I do it the day after I close?

I’m looking to get a new Cap1 card, a Costco card, and a Lowes card.

Any suggestions/feedback?

Thanks!
