condition=* is a property that usually describes the physical working condition of an object, such as good, fair, poor, etc.
Qualitative tags like this have problems with low verifiability, which is that one mapper's "poor" might be another's "fair".
condition=* can also have issues with ambiguity (i.e. which of the tags on the object is in "poor" condition?). This can be addressed by using condition as a suffix, such as with building:condition=*. Beware that this usage clashes with condition in the sense of a constraint: parking:condition=* describes what conditions must be satisfied to park.
