Also take into consideration the age of the debt in question and if it is inside or outside SOL. Generally, the older the debt, the more willing the CA is to accept low settlements. It is also a good idea to find out if they have purchased the debt or if they are collecting on behalf of someone else....and if the owner is the original creditor because if it has been bought, they did not pay full price for it and you can also take that into account when negotiating. Whatever you do, make sure that part of the deal is an update with the CRAs (removal is best, settled or paid is good too, but anything with 'less' or 'collection' in it is not worth your time and money since it is nearly as bad as an outstanding debt.
