Beware. Rentalsource is a funnel for apartmenthunterz. (who carries complaints of re-listing false/stolen/out-of-date listings and collecting registration fees from rental seekers in exchange for false information.
Here's my experience today [protected])
"Rentalsource" had an apartment listing. I typed in to ask for more info about it. I immediately received a reply from "apartmenthunterz" that said this apartment wasn't available. They offered an alternate listing. But I've already called on the second listing from a Craigslist ad and it's not available and not their listing. I was asked to register and pay to get contact information that's free on Craigslist, has a different agent (property manager) and doesn't belong to them.
I can find no evidence that the agent named on "rentalsource" for any of the many apartments listed under this name exists.
Rentalsource is just a funnel for the apartmenthunterz..
