It is possible that through the apartment showcase, the potential renters can expect to get high-end amenities on the property. Through this showcase the potential apartment renters can have it customized to their preferences. There are also other people who would prefer that their apartment space contain lots of cabinets and an island kitchen. The apartment display is actually trying to resolve potential problems arising after the purchase.
You can see through the apartment showcase if the management has invested money for the unit owners. Is there available cardio equipment, free weights, exercise balls and other machines for the number of renters? You may even prefer the free community type where there is WiFi area, phone and fax capabilities and business center too.
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.
