No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Check to see if there is an actual public record for the repo (judgment). Look in your county records because the bank will check.
Before you ever make application, if this is a judgment, take care of it. Once you make application for a mortgage, the CA will see it and become much less negotiable.
Does it report as a collection or judgment? Or is it reporting as a charge-off?
So with a charge off, FHA doesn't require it to be paid or in a repayment plan or automatically count 5% of the balance as a monthly payment. That guideline only applies to collections & judgments. However there is a chance that an underwriter could require it to be paid. You could apply and see what the underwriter says, but have the money to pay it just in case. It's also fine for you to settle on the account, if a lender requires it to be paid off you don't need to pay in full, just that it'd be a $0 balance.
