Build Brown Houses
When starting the game with limited resources, it is a good idea to place single brown houses on as many spaces as possible. Brown houses give you the best return for money spent available in Monopoly Millionaires.
Smart Power Management
Paying your power bill is a good idea as it allows you to earn lots of money even while offline. Don't pay the bill for too long, though, as it will end up being a waste - pay for too short a time, however, and your houses will go dark and not be able to earn you any money.
