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.
Once you have located your "dream apartment", or as close to your perfect apartment as possible, now it is necessary to pay extremely close attention to the particulars of the rental agreement. An Apartment Lease is a contract between you and the landlord. Once agreed upon and signed by the tenant and the landlord, the rental lease creates obligations and restrictions for both parties. The most obvious covenants of the apartment lease are the length of the rental, (Six month lease, one year lease, two year lease, etc.) The amount of the security deposit, when the rent is due, who is responsible for what utilities. Also in that apartment lease, however, are stipulations, (sometimes in small print) that can cover a great variety of landlord and tenant obligations and restrictions.
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.
