How can my husband raise his credit score quickly?

He needs to raise his score a little in order for us to refinance our mortgage. He only has one credit card in his name which he doesn't use, he only pays off. Would it beneficial if I added him to my credit card (as a secondary cardholder) which I use frequently and pay off monthly? What else can we do??How can my husband raise his credit score quickly?
He might try simple credit repair to remove any negative items or errors. He could get a 40 point bump or more in 45 days or less.How can my husband raise his credit score quickly?
I don't think it's a quick process. One thing he can do is use his credit card more often, but the important thing is to have the money on hand first.





Don't pay things off completely. If you spend 100 dollars, pay 50 dollars for the next two months. Credit is basically a history of someone responsibly paying for credit debt on time. If you payed the 100 dollars before you get the bill, its like it never even happened.





You will have to pay interest but its a small price to pay to help get good credit.








I'm not sure about putting him on your card unless you're in debt with that card and he can help pay it off on time or something..
