No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
DV them as you would any other collection agency. Also check your state resources and see if they must be and if so ARE licensed in your state. The foreclosure has already done damage to your credit report and while yes the insertion of a collection account would do some more.. Make sure you follow the correct steps from the onset of the process.
Best of luck.
