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.
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.
