Just got new rental question on viewing? ????

[Bernie Avila]

I got my second rental this week and posted on Craigslist. I've had 2 people go view the property and one coming tomorrow. The 2 people that have viewed the property both want it. I really liked one family but he other family just gave me a funny feeling. Now since its equal housing opportunity do I need to run background checks on both families or just the one that I want to rent to in order to  fair?
