What do you call a person who owns your house?

Answer 1

It totally depends on the reason you are entitled to stay in the house. If it is because you own the house, the owner is you. If it is because the house is owned by a relative, and you are living there as part of the family, you call the owner father, mother, grandma or otherwise as the case may be. If you are not a member of the family and yet are not paying any money to stay there (as an exchange student might for example), you call the owner your host. If you are employed as a live-in house servant of some kind, you would call the owner "Boss" if he or she is your employer. Otherwise you probably have no contact with the owner. Only in the case where you are entitled to stay in the house as a result of a lease from the owner would you call the owner Landlord.
