I know we cannot discarnate due to race, gender, disability, nationality and religion. 

But I would not do multiple background/multiple genders folks as room-mate as there would be higher safety issue and continuous drama.Also if you can, try to find property where you can divide the wall, and add bathroom/walls/kitchen,etc.

Word of advice...when renting by rooms, keep it all one gender. 

It's not always a one gender or the other, but more a sense of opposites attract. 

I think that there are two camps trying to make this change.The PC camp is trying to make the change because the word is allegedly gendered (even though landlady is available, landnonbinary and landgenderqueer are not yet popularized).

Prevents discrimination against protected classes (race, family status, gender, etc)How often will I get updates on my portfolio?

The Fair Housing Act - which applies to private landlords too - makes 'it is illegal to discriminate in housing on the basis of a person's race, color, national origin, religion, sex (incuding gender identity and sexual orientation), familial status, or disability." 

In my experience I would recommend avoiding any mention of an applicant’s family status, gender, etc. when discussing your tenant placement decision  (“couple with 3 year old daughter”, “single male”, etc.).

And lastly, if you want to pay for blue and pink hair kids to get gender studies degrees, be my guest, but don't try to force that on the rest of us. 

Credit reports have racial and gender bias.
