Collecting balances for current and previous tenants are two different matters.
For current tenants I recommend never allowing a tenant to become two months behind in rent. When a tenant is allowed to go two months the chances he will catch up are slim. Most likely he will either skip or be evicted owing you a lot of money. You mention damages. If a current tenant damaged my property he would either pay to have it repaired or leave regardless whether the unit was affordable or not.
For previous tenants you have three choices to collect debt.
1. Court- Depending on where you are, and the specifics about the debtor, this option may not be worth the time and money you would spend going to court.
2. Hire a collection agency- If you do hire one make sure you hire an agency that specializes in tenant debt. Know that all agencies are having a difficult time collecting in this economy.
3. Report the debt all three credit bureaus- This is the option I recommend in this economy. Report the debt and let it follow the debtor for seven years after move out. Eventually the debtor will have to clean up his credit report and pay you in order to obtain credit.
I have a lot more information on the subjects of tenant debt and screening at my blog.
