auction rule never comes up because who doesn't buy every single space they land on
-Players who are currently pouring all their money into housing development
-Players who land on a low-value property such as the third of a colour already owned by two other (different) players
-Players in dire straits financially unless the property in question is game-savingly valuable
There are probably other circumstances.
Also I've never heard of this "circle the board first" house rule. That sounds awful. There are much better ways to negate the luck of who goes first, if you even decide that's worth doing.
