Collections for back rent
Hey all! In my previous life as a dumb landlord, I let a tenant not pay for a few months. Once all was said and done and after a few hundred in damages were fixed, they still owed about $4k. They agreed to a payment plan and were actually paying for a few months but have stopped. So, I want to send them to a collections agency. Are there certain collections agencies that deal with this type of debt? Anything I should be looking for in such agencies? Thanks!
