Can You Trade Properties That Have Buildings?

Yes, but only after all buildings on the entire color group are sold back to the bank first.

The Official Rule

In Monopoly, you cannot trade, sell, or mortgage any property in a color group that has buildings on it — even if the specific property you want to trade has no buildings itself.

The restriction applies to the entire color group, not just individual properties.

What You Need to Do

To trade a property from a developed color group:

  1. Sell all buildings on every property in that color group back to the bank at half their purchase price
  2. Once the group is building-free, you can trade any property in it
  3. The new owner can then rebuild if they complete a monopoly

Example

Say you own all three yellow properties and have houses on two of them. If you want to trade one yellow property (even the one without houses):

  • First sell all houses on both developed yellow properties
  • Then you’re free to trade any yellow property

Why This Rule Exists

This prevents exploits where players could trade away part of a monopoly while keeping buildings that require a complete set. It keeps the game balanced — buildings represent an investment tied to owning the full color group.

Quick Summary

  • Buildings on any property in a color group blocks trades for all properties in that group
  • Sell all buildings first (at half price), then trade freely
  • This applies to trades, sales to other players, and mortgaging
