Welcome! I recognized the name and couldn't figure out why, you joined DISchurners but were a lurker on the thread here
Thanks for coming out of "lurkdom"!
So your husband appears to be 6/24 but he will have 2 cards drop off and be 4/24 in August (is he an AU on any of your cards? - that would make his number higher). You appear to be 8/24 or maybe 9/24 with 3 cards dropping off in the next 2 months. You probably already realize this, but your AU situation is a bit of a mess.
My first piece of advice would be to undo as much of the AU situation as possible. Remove each other as AUs and ask the credit bureaus to remove the accounts.
Were you following our fun discussion yesterday? We were talking about the various side hustles and hobbies we all have that qualify us for small business credit cards. Do you and/or your husband have an activity that would qualify you for small business cards? That could include things as simple as selling on eBay, teaching piano, consulting, mowing lawns, tutoring, babysitting, etc. I really hope you have something as that would open you up to some nice opportunities. I'd actually recommend you look at AA (American Airlines) business cards while you work through the AU cleanup. You and your husband could potentially each earn a quick 100k+ AA miles from 2 biz cards without further hurting your 5/24 status. (Those cards would be the Citi and Barclays AA biz cards).
At any rate, I'll stop now and let you maybe respond to some of this
