My uncle has lived in my house for six years and can ask him for rent. According to relevant public information, rent refers to the rent paid by the renter to the owner of the house, which is the money needed to rent the house in a popular sense. My uncle has no money and can borrow it for a short time, but he can ask for rent for a long time.
