Rental ads - Littleton / Denver CO

[Tony SanFilippo]

Hey wanted to see what other investors have been successful using for advertising their rentals. 10 years ago Craigslist did it all, now almost no one is using it for rentals. I use Turbo tenant (who syndicates to apartments.dom, realtor.com, facebook and others), Zillow and the MLS. Response has been slow the last few weeks and wondering if there are some new locations for rental ads? I did increase my rent, so I understand I may need to drop the price to get more action, but thought I would see what everyone says.
Thanks
