If you are asking for a cheat ther is none. But there is another way. first you will need to complete the level where you kill lance vance.you will then own the house and get a check on the front steps for about $5000 every day (every 24 hours, gametime).next you will need to complete the asset mission for the malibu club, the poleposition strip club, the paperworks, the cherry popper ice cream factory, the dock by the truck place, sunshine autos, and the porno place on prawn island. once you have completed all of these mission you will get $35000 a day just for owning these businesses.this is about the most money you can get.and also you will have to go back to these places to pick up the checks.you also get special prizes that come with owning these places like new cars, a plane,and even a ice creaM TRUCK.

this is the best way get a cop car take it to any hide out and start the missions for it drive the car into the garage get out let the door close and do the cheat that blows up all the cars then the threat wll be gone get back in the car and wait for the yellow blips to appear on the map get blow up the car and each time you do this you will get more money

You can also go to the Army Base and get the helicopter, do the missions with it and if you do enough you'll start racking up more than 100,000 dollars.

Well in this game you don't have any cheats to get more money, but you can do it the hard way like for example, kill people and take their money, buy places and get the income, do missions, drive the taxi, or do the rampages.
