Start a 6 player local game using 1 controller. All human, no AI.
After you start the game just auction every property that every player lands on and win them all with your player until you get a set of 3 to build on. The first set of property you can earn over M700 is the light purple set with Virginia Avenue, States Avenue and St. Charles Place. You will need to build hotels on these properties to earn that much.
You can build on more property, just make sure the houses or hotels needed are on the property to earn over the M700.
If you don't have enough money, just trade with another player where you give M1 and take all you need from the another player.
Once the property can earn over M700, just keep rolling the dice until another player lands on it and pays you rent.
