The mortgage companies aren't going to go off your FICO 08's. They use a different version. Unfortunately for you, the mortgage score versions are more sensitive to maxed out cards and multiple cards with balances, so your score will be probably lower and take you out of prime rate territory.
Did you ask the mortgage company what your scores were on your 3 bureau report that they pulled?
You should have paid all of your cards to $0, and left one to report with $2-$5. It's called the $2 trick and it is most effective for mortgage scores.
