The person who collects the rent is called a "rent collector." This term specifically refers to someone who goes from house to house collecting rental payments for the owner of the property.

Other related terms include "landlord" or "lessor," but these generally refer to the property owner rather than the person hired or assigned to collect rent.

Regarding "Dan word," if it refers to a specific name or term, there is no direct association with rent collection from the standard terms. If more specific clarification on "Dan word" is needed, please provide additional context.
