Tenant Discrimination (House Hacking)

[Blake Reynolds]

If I am trying to rent out 2 spare bedrooms in a property that I own and live in can I be more selective as to which tenants I select since I also live in the house? Not that I would actually discriminate due to race/color/religion etc. but could I use personality/age as a reason not to accept someone who applies for one of my bedrooms. 

I want to be careful not to get in any hot water when declining prospective applicants. TIA.
