Be realistic about what you can afford. Most apartment renting guides suggest that your rent should not be more than 25% to 30% of your income. This can vary depending on the income bracket, but be sure to be "real world" when budgeting additional apartment expenses such as heating and air conditioning and other utilities. If you fall short of affording the apartment of your choice, you might consider sharing an apartment with a roommate or roommates. Keep in mind that living with roommates can help you afford an upscale apartment or even, in some cases, luxury apartments, but it also has extreme restrictions to your privacy.
Narrow your apartment locating to the size of rental unit you need. Studio apartment or one bedroom apartment or 2 BR apartment or more. Are you considering a furnished apartment or do you possible need a short term rental. If you are renting an apartment with a cat, dog, or other pet, you need to find out which apartments allow renting with pets and which do not. And, if they do allow pets, is there an additional security deposit required and if so, how much it is. Do you need an apartment complex with an exercise room or tennis courts or a pool or a recreation room, etc. or do you simply need and desire a nice clean and quiet pad.
When you are apartment hunting, prepare a rental search plan. Be sure to know in advance what you want in an apartment and what you can live without. Decide in advance what areas of the city you could consider living in and make a list of apartment buildings within that perimeter.
