Am I creating a potential discrimination claim for myself?

[Craig McCarter]

I have one rental property - a house that I used to live in for 5 years. Each of the past tenants have been great and I have been very transparent with them - we're looking for the right fit, someone that will take care of the place, not be a headache, etc. Basically out of all the people that were interested, I have chosen the people I liked/trusted the most. 

The unit is coming up for rent again soon and I'm wondering if I am opening myself up for a claim of discrimination with this process - where a tenant who is not chosen could claim that I rented to someone else based on their (fill in the blank of protected class)?

Any tips on how I should potentially navigate this differently? but also, I really like being able to hand pick my favorite from a pool of applicants.
