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.
So, if you are searching for a new apartment where you can stay, expect to see more than the small box. You can set your preferences and know if the management meets them through their apartment showcase. That way, you can find the apartment that is fully furnished with your taste. You may really not need the help of a property manager if you can see for yourself what the apartment has.
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.
