Reference check for tenant for "small storage space"

[Ian S.]

Hi, I got a voicemail out of the blue from a guy who says he owns a small storage locker and is doing  a reference check on my tenant to see if he pays his rent on time.  My tenant does indeed pay on time and he's a good tenant, but I thought it strange that the guy who called is just some guy, and not a company. I'm thinking I check with the tenant to see if it's a legit reference check, then provide the info.  Does that make sense?
