Honestly, if you are looking to rent, I would contact an agent in your area and see if they would be willing to help. Agents have access to investors, stagnant homes that aren't selling (maybe their seller needs to move and would consider renting out their home!) and other relos and rentals.
Another option is to go to the community boards in your area, maybe at a grocery store or a community college. Usually rentals are posted there as well.
