You'll regret this defense of staying in the closet in 5, 4, 3, 2...
I am not recommending staying in the closet. There is a difference between staying in the closet and advertising one's affectional orientation. He could have avoided using the word "boyfriend" and simply said "friend" when phoning prospective landlords. If asked over the phone about the friend's gender, he cold simply have answered that he is another man. That carries a fairly neutral connotation whereas "boyfriend" strongly implies that he is more than a friend.
There is such a thing as being practical and not asking for trouble. After renting for some time, they could, without making it seem to be an issue, gradually reveal that they are a couple. Treating it as a mundane fact of life is more likely to result in a favorable response. In any case, it would be less likely to elicit a negative reaction and would be likely to improve the attitude of the landlord and other tenants towards gay persons.
There are many ways to come out of the closet. It does not always require hitting people over the head.
