Use a RE agent to rent out a higher-priced rental house?

[Lee Badragan]

I bought a house in the Chicago northwest suburbs and need to rent it out. Market rent is $2,500-$3,000 per month. This is a house that I plan to move into 3-5 years from now, but need to rent it out in the meantime. 

I have never rented out a house before, so am looking for some advice on whether I should post the listing myself on craigslist, zillow, etc... or if it would be wiser to have a RE agent post it for me, along with putting it on the MLS.

Are renters looking for higher-end rentals more likely to be working with an agent and would need to have my rental on the MLS? Or would I be wasting my money having an agent list it instead of taking care of it myself? Thanks!
