Building
How you build may be your most important strategic decision.
No matter how many monopolies you own, DO NOT start building on more than one monopoly until one of the monopolies has at least three houses on each property. The jump in rent between the second and third house will have more effect on your income than will having monopolies in more than one location, if none of them has at least three houses. A graph showing the importance of a third house is provided on page 119 of Philip Orbanes' The Monopoly Companion.
When deciding where to build, note where your opponents are on the board. If you are playing with dice, remember the numbers that are rolled most frequently: 6, 7 & 8. You may not have many opportunities to collect substantial rent; therefore, you may need to take the risk of developing your properties as fully as possible, as quickly as possible, depleting your reserves, and either mortgaging or selling your properties that are not in a monopoly.
Because houses are less expensive on cheaper color groups, it takes much less money to reach the important three house level; therefore, cheaper color groups may be more valuable than their title deed cards would indicate.
