All I can say is, I talked at great lengths to SW about bankruptcy, and how to rebuild their credit afterwards.
You rebuild credit by showing you’re credit-worthy. One way to do this would be to get credit cards (which would have incredibly high interest rates due to their creditworthiness after a Ch 7) and use them. Of course you’d be expected to make regular monthly payments to establish good credit.
Not sure if that’s what you’re implying.
