Employment Verification during COVID Times

[Philip Briskin]

I have a rental that is turning over the end of May.  I listed the house for rent on Zillow, and have received several inquiries for the house.  Some have gone as far as to pay (through Zillow) for an application which includes a background check.  I have spoke with a few of these prospective tenants and have used SmartMove - TransUnion to run my own background check.  My question...while both the Zillow and TransUnion say that they are employed, am I over-stepping any boundaries by asking them for either an employment letter or their last pay stub to ensure that they are STILL employed, given the conditions right now?  

Any assistance is appreciated.  Thank you!
