Bankruptcy (but great credit score?)

[Clare Cui]

Hello all, 

I have a prospective tenant for a rent by room strategy, we're in initial stages (he hasn't officially filled out the application to verify his credit score) and he is letting me know he filed bankruptcy in 2020, but his credit score should be above 620. 

Any thoughts on a good credit score but a bankruptcy in the past? I could also ask him to provide a report from his business (he is self employed) of his P&L and transaction reports to make sure he is making money etc. 

Thank you in advance!
