Don't use the cheats!! It will mess up your save file and you won't be able to "win the game".
The best way to go about the game by spraying all the tags first so you have all the weapons at your hideout. You can find a tag map and walkthrough by googling it. I forget, where are the pimp missions?
there when your in a pmp car u press R3

Everything you need to know is there, and yes using the cheat ruins your save and takes all the fun out anyways.
But if you want to cheat without really cheating save and go to the horse betting place. Then bet on the horse with the WORST odds, 8-1 or 10-1 I think. If you lose reload and repeat. If you win save and repeat. After about 6 or 7 wins you will have enough money to buy every property etc etc
