how to collect unpaid rent after tenants moved out ?

[Hisashi N.]

We have handful rental properties and manage them by ourselves. We have filed eviction to local county court numerous times and tenants moved out. However, we have  never been able to collect unpaid rents (typical amounts few thousand dollars, 2- 3 months worth of rent). What is the realistic way of collecting unpaid rent, even partially ? Using a collection company, filing a claim to munincipal court ??

I have asked this questions to local REIA members, but no solid answer was provided... Do landlords simply give up ???
