Screening for MTR and Coliving (Education Requirement?)

[Kristine Ann]

Dumb question, but is coliving (renting out rooms individually) and MTR the same thing?  

I'm looking into starting renting individual rooms in an area that has a housing shortage.  I'm thinking of making the main requirement to live in the home be a master's degree.  I'm looking to rent to new teachers and health professionals and my thinking is that besides nurses, most have a master's degree or are currently working on their master's degree. Is that a strange thing to require?  I'm just trying to think how to create a community of individuals who will get along and are similar in some way without discrimination.  

Also, can I insist on single occupancy in each room without violating antidiscrimination laws?  I'm not against couples, kids or families at all, I'm just concerned about the ratio of people to bathrooms.  I'm accustomed to the regulations on LTR, but not sure about MTR.

Are there any resources you can recommend?
