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.
If you do not understand every single clause of that apartment lease then do not sign it until you do understand it. If necessary and if possible, request assistance in interpreting the lease from a trusted source such as a knowledgeable friend or family member or employer or professional, or anyone else who can understand it and explain it to you. If necessary get legal advice. It can cost additional funds if you do not qualify for free legal assistance, but that additional cost might save you a ton of money and save you a ton of heartache and aggravation down the road.
Prospective tenants should read an Apartment lease thoroughly. Prospective apartment renters should understand everything that is contained in that lease and make an informed decision to be 100% accepting of all the provisions for both the tenant and the landlord, that you are positive that you can live up to your end of the bargain and that you are comfortable with the provisions on the landlord`s end.
