Everything free (except bulldozing and tax)
At your city hold Ctrl + shift + alt + C. A box should appear at the top left hand of the screen. Type "I am weak" and then press enter for just about everything to be free.
To get $100,000 get the cheat box to come up and type "call cousin vinnie" and press enter. Not go to "meet" and there should be a pentioner there offering you money.If you accept, you get the money. If you decline his offer you get a SIM castle for your city!
