Some questions about how to play a game of Monopoly are not answered in the official rulebook that comes with the board game (not surprisingly). For example, under the header of Building Shortages...
When the Bank has no houses to sell, players wishing to build must wait for some player to return or sell his/her houses to the Bank before building. If there are a limited number of houses and hotels available and two or more players wish to buy more than the Bank has, the houses or hotels must be sold at auction to the highest bidder.
Several questions come to mind...
Suppose multiple houses are available that two players wish to buy. Is there a single auction for all houses in contention (i.e., with bids like "$100 per house"), or is each house auctioned one at a time?
If houses and hotels are in contention, the result of one auction may influence player decisions in another, or if hotels are auctioned first, even make auctioning houses unnecessary as more return to the Bank. Who decides the order of auctioning between houses and hotels?
Is there a specific order that actions between turns are executed? For example, suppose Player A wishes to buy the last house in the Bank and has enough money on hand to purchase it for at least one of their properties they could put it on, and Player B wishes to buy the house but would have to mortgage or trade with another player to acquire the cash to purchase it for any of their properties they could put it on. Presumably, Player B cannot immediately force the house to go to auction, since they could not legally buy the house normally, but can Player B perform other between-turn actions, such as mortgaging or trading with another player, before Player A has a chance to purchase the house? How is priority to act between turns managed?
Broadly, I am interested in how these types of questions should be answered as objectively as possible. I know there are official Monopoly tournaments, so presumably answers to these types of questions have been worked out. Is there a more advanced rulebook or other official rule source that teaches how to play Monopoly in more detail?
