Finding rental apartments outside of craigslist and MLS

[Kevin Schaefer]

Hello, this may have been covered but I didn't see it in the blogs. I recently got my NJ License and have been trying to do rentals to make some cash while I work on getting listings. Aside from Craigslist and the local MLS (njmls) what is the best place to find apartments that might meet my clients' criteria. I have 2 different people that want apartments and nothing on craigslist or mls is meeting what they want. I thought there would be a section in the Marketplace on Biggerpockets to throw out to all the landlords on this site, but it doesn't seem like this fits anywhere here.

Thanks and apologies if I'm missing something really really obvious.
