If you have seen the play book of Mormon you can get the drift  LOL  just kidding 

The FHA, to date, includes seven protected classes: race, color, religion, national origin, sex, disability, and familial status.

Mormons are highly educated and business savvy... 

To answer your question: in theory, you can rent any place for any amount you want and can disqualify people for any reason so long as it's not a protected class (race, religion, etc).

As long as you are correctly informing your custodian and they are preparing your IRA reports accurately, the rest is just interesting cocktail conversation like religion and politics where everyone has an opinion and few people change their minds. 

Source of income is just like any of the other protected classes...race, religion, familial status, ethnicity etc.

Dont think its about religion at all.

If not, you may even be setting yourself up for possible fair housing violations if the other tenant is a different race/gender/religion etc.

The late nights discussing politics, religion, and world affairs with people from all different walks of life can truly help make you a more thoughtful and compassionate person.

Jesus is not religion.
