Rental property not moving - how long?

[Jamie Bergstrom]

Hello, we are in the midst of moving and want to rent out our unit (Buena Park area in Chicago). I looked around the area and knowing the size of our place, number of beds/baths, plus other benefits such as it being a top floor unit, two parking spots and dogs allowed.. I feel it is priced fairly. However, we are not having much interest. How long have your properties been listed before seeing interest? How much in advance of when it is available? When I was a renter years ago I began looking about two months prior to needing a place. Also, sites you have had best luck getting interest? We have our place posted on Zillow (and rental network - Trulia, Hotpads), Domu, Craigslist, Padmapper, and Apartments.com.

Thanks in advance!!
