Inspection concern (tenant issue)

[Nidia C.]

Hi everyone, I have a home inspection scheduled for this Saturday in Paterson. The seller explained that the tenant might give me a hard time with the inspection. Reason being that the seller told the tenant he was going to start the eviction process since the tenant wasn't paying rent. 

I worry that the tenant won't open the door, and I'll waste my inspector's time. My main question here is do you have any tips on how I should approach the tenant/situation if they refuse to open the door. How I should introduce myself? Any suggestions?

FYI. The seller doesn't have keys to the property.
