The more you have, dollars and/or accounts typically will get you the best rates. Age of accounts is also a huge factor. Accounts aged 30/60/90 days are more desirable and collectable then ones that are over a year old.
Judgments and Landlord-Tenant
Low 15% High 50% Average 40% plus 10% upfront
These types of files are tricky to negotiate, the most successful companies need an upfront fee to execute a judgment. 10% of the judgment amount upfront plus an additional amount on the backend will typically get you the best results.
