Help w/ Deal! I need to negotiate down credit card debt

[Joshua Hill]

I came across a deal knocking doors on the pre-foreclosure list, and in negotiations with the seller, she wants enough money to pay off all her debts from the sale of her manufactured home. In order for this deal to really be a win for her, I need to pay off her debts. In order for it to be a deal for me, there needs to be more margin than what I'd get paying enough to settle her debts.

Here are the numbers:

• 45k ARV
• 5k Rehab
• 15k home loan
• 12k credit card debt
• 4k car loan debt

The clearest way to both help them out and make enough margin for me is to get third party authorization and negotiate down the credit card debt. However, I've never negotiated with a bank. I haven't talked to the homeowner about this yet, so I don't know if/how far behind they are. Without knowing this important information, what is the best advice you have on how to negotiate with the credit card company, and what I can expect them to come down to?

Thanks in advance!
