walk around the neighborhood you're thinking of renting in, and look around for signs advertising rentals with phone numbers on them.

call them with the bdrm count you're looking for, and if they know exactly what building you're talking about and units they have available, sometimes they'll give you the code to walk right in and check the place out.

you can use this convo to push the rate down a bit or ask for a rent concession, and since you're likely talking to the landlord/agency it'll be no-fee.

that's how i've found my last 3 rentals :) gl!
