I guess if you're asking about an apartment on Trulia, most of them are posted by brokers and agents.
Some are by landlords, and Management company's. Management company's and landlords normally don't charge Brokers Fee.
Brokers and agents normally do.
I hope that i answered your question, or i was any help. and if you have any other concerns. Please feel free to give me a call
and i'll be glad to answer any question.
