Before finding the unit you like
Application of occupancy must be handed before the preparing of an offer
(Dont Worry is just basic information... name, adress, work, etc). This will SPEED up the process once you find the DREAM rental. Also remember to bring your ID and a check for the first month's rent to send along with the offer.
Some landlords WILL ask for a credit report (can be obtained @ www.creditkarma.com with the free trial) and/or a background check (can be obtained @ Doral police station for 5$).
