You get half of what you paid for put toward your next apartment. There are a bunch of videos on youtube showing the layouts...a lot of the higher end ones have the same features (and in some instances less features for the more expensive) but the view and location is what people find best.
looking back, I like the apartment I have at richards majestic..but I'd of liked to have gotten the one right next to the skate park as I ride BMX bikes usually right when I start playing or right before I quit.
A ten car garage is nice, but I only need like..3 or 4 vehicles max anyway.
so, don't feel like you need to make your way to the 400,000 apartment...but do find one that suits your character and fulfills your future needs.
