It will be difficult because the law is very clear on that, and not in a good way. I can run background checks. I can make a slightly higher-end house and charge more in rent. I can charge a full-month's rent as a security deposit (as opposed to a smaller amount). Those choices should help weed out many of the least desirable. I can avoid following vasto shastra, the hindu equivalent of feng shui. I can invest a lot into trees and making it look natural. Whites will pay extra for that, others won't.
