Yes, you can try and apply for a loan after bankruptcy. But it is not a good idea to apply shortly after filing because you risk being denied. It will be better if you wait at least a year. After that you will be able to apply for a secured credit card. Secured cards have lower rates and fees than CareCredit. Also if you use your card responsibly (make payments on time every month and stay within the credit limit), you will be able to request an increase. Most credit issuers allow up to a $3,000 credit limit increase on secured credit cards. They can be used everywhere credit cards are accepted, whereas CareCredit is only for medical treatment at certain doctors.
If you decide to apply, don’t forget to check your credit reports and credit scores, the bankruptcy might have significantly lowered it. Also, make sure all the records are correct in your credit reports.
