Trulia doesn't list rentals. You can review Craig's List, conduct an internet search, walk around the Bronx looking for apartments and neighborhoods yourself or you can hire a Realtor to help you with your search. As a renter, you will be responsible for paying the broker's fee unless the owner is willing to pay for the fee or unless it's a no-fee apartment. If you hire a Realtor, I suggest hiring a Realtor from the Bronx or has extensive knowledge of the Bronx. Good luck.

Sorry Carmen
