Which prospective tenant gets my house?

[Ken Gurta]

I am showing one of my homes to 3 separate applicants. I have reason to believe that all 3 of them are going to pass credit and background checks. I do not know who contacted me first as they contacted me on the same day via different means. Therefore, I can not simply tell one applicant that he or she gets the first opportunity. Also, I'm not sure what to say to the 2 applicants that I have to decline. How would you handle this situation? Thanks.
