The screening process and time is the key to your question.
ADVANTAGE: An agent could clear up some of the major concerns with hows coming and when.

DISADVANTAGES: Time and can they Afford the rent, most landlord request credit checks.
How safe is the apartment, you might not kown the area that well.
There are some listings that are in house only. But if you are comfortable with an agent, employing

As far as real good apartments in my taste and price range, I've seen pretty much everything online that brokers have been showing reccomending me, at least in this current state.
