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.
If you are familiar with the area and its neighborhoods, that gives you a distinct advantage for your apartment search. If, however, you are relocating to a new city or are not particularly knowledgeable about the city, you may want to contact an Apartment Locator or an Apartment Finder.
As a potential investor for such apartment home, you may want to know of the extra facilities that your future home boasts of. Is there swimming pool in the complex? Some expect to see hot tubs and saunas on the site. Others prefer that there will be fitness center in the apartment building, which they can join.
