Waiting for the right rental

I'm in no rush, but I'm looking to move to a 1 bed downtown or west of downtown. Probably in the new year.

Is there any anecdoteal evidence of being able to get a place for slightly less than advertised? Some of the units I'm seeing online are just not worth the money when you're on the 3rd floor above a busy intersection.

And another question, where's the best place to search? Is there somewhere you can filter on things like floor, orientation? I'm currently using pad mapper and FB marketplace.

Thanks in advance!
