i have always found that Craigslist.com has the most rental listings!

If you are looking for an apartment, check your local area and see if there is a company similar to "Apartment Hunters" or "House Hunters". Online source can be Craigslist.org. You can also call "Property Management" firms in your local area, as they have a current list saying which properties are available now, or next month. Happy Hunting!

Rentclicks.com or Craigslist.org are good places to start. Local newspapers online or printed, of where you are looking are good ways to start too.
