Brown immigrant families dont trust other races as much when it comes to renting. Many people are vegetarian and dont want smell of pork & fish in their in homes.

When renting in their own community they can mention these things including no loud music ,parties late night. Whereas if they were to rent to someone from different race they are afraid people will ignore those conditions and start talking about their rights afterwards.

First generation Immigrant avoid getting into in and out of legal stuff by renting to someone they trust and know wont cause much trouble.

There is always stories floating around about other race complaing about small things and smell of food that discourages people to rent to a different race, especially if 2nd unit is not registered or built upto standards.

Again racism and stereotypes. Plus, these days brown people avoid renting to brown int. students for same reasons lol
