Collecting unpaid rents after judgement

[Anne Jenkins]

Have a unit that the tenant moved out before the eviction, but have judgement on the unpaid rents and damages.  Before I proceed, I was hoping to hear from those of you who have successfully collected.  What is the next step.  I know the tenants new address.  I know he has assets and a significant disability income.   In addition he runs a handyman under the table business.    Looking to collect but wondering what my costs will be and the pitfalls of the process.   Thanks to anyone who can shed some light.
