Based on standard two-dice rolls from GO. Properties near Jail are landed on most frequently.
Value Score = expected rent income weighted by landing probability and housing cost.
• The orange set (Ventnor, Marvin Gardens, Connecticut) is the best value for the price because
players sent to Jail frequently roll out onto these spaces.
• The red set offers excellent return on investment with moderate cost.
• The dark blue set (Park Place, Boardwalk) has the highest individual rents but is the worst
value relative to cost & landing probability.
• Monopolies with houses are far more valuable than hotels on cheaper properties.
• When trading: prioritize complete color sets over individual expensive properties.
More Monopoly games are won and lost at the negotiating table than on the dice. The trouble is that a property's face value tells you almost nothing about what it is really worth. This calculator scores a proposed trade using rent potential, how often each space gets landed on, and whether the deal completes a color set, so you can tell a good offer from a trap.
Enter the properties and cash on each side of the trade. The tool weighs each property by its rent potential and landing probability, adds the value of completing a monopoly, and returns a fairness score showing who really comes out ahead.
A property is worth roughly its expected rent multiplied by how often opponents land on it, and that value jumps once you own the whole color set, because rent doubles on undeveloped monopolies and multiplies fast with houses. Landing probability is not even across the board either. Spaces just past Jail get visited most, since so many players leave Jail each game, which is why the oranges and reds are prized far beyond their price tags.
You are offered a cheap purple property plus cash for one orange property.
Does it account for landing probability? Yes, high-traffic spaces are weighted more heavily.
Does it value monopolies? Yes, completing a color set is a major factor in the score.
Can I include cash and multiple properties? Yes, on both sides of the trade.
