For example, if you don't specify if a certain item is reoccurring or 1 time, you can't collect it.

Get the judgment and frequently the court personnel will instruct you on how you can collect.

@Michael Darten  Most property management agreements have the monthly PM fees based upon a percentage of rents collected.

Just a point of fact Class action suits are a pipe dream at this level in almost all circumstances. there has to be money to collect.
