It is actually possible to negotiate a pretty good settlement with payments that are broken down into monthly and reasonable payments that you can afford. As erb says, you must have a plan when you call, have a detailed plan ready to go, once you have contacted them, confirm the address and tell them that you will be sending a written proposal, you will need this documentation later to make them follow through with the agreement. Some things that you may want to put in the letter may be:
1. Agreement to a said amount XXXX, with monthly payments of XXXX, paid in # of payments, place monthly payment schedule and final payment information.
2. What results do you want in the end. They agree to remove the negative status and provide the credit reporting agency with updated and improved status of account.
3. Any revision of the agreement will be in writing and approved by both sides of the agreement.
4. Account will be considered paid in full and any remaining balance will be considered satisfied, not to be sold off to another collection agency to start this process all over again.
Goodluck with this, please keep us updated on your progress, It is a long road, went through this with two companies last year, had some pretty satisfactory results. Some of these things I found out the hard way, hope this helps you.
