My son is looking for an apartment to rent with a friend of his. All of the complexes we visited have some sort of income requirement, usually gross income of at least 2.5 to 3 times the monthly rent. In one complex, the representative told us that both boys must qualify separately for the total rent. The "boys" are 24 and 26 years old respectively, and meet all other of the apartment's requirements. I asked if they had the same requirement for married couples (both must qualify at three times the rent) and they told me that it is different for married people because one of the boys might leave. This seems like discrimination against single people and a violation of their civil rights. Am I right?
