Are C class tenants in worse shape than b class?

[Gordon Starr]

I have eight active sf rentals. Six are c class and two are low B. Last month the b class tents both came through with full payments, but two of the six c class tenants could not pay due to Covid Layoffs. What are your experiences with c class tenants? How do I tell the delinquent tenants they need to pay if they want to stay ? I’d hate to put them out, plus eviction court is temporarily cancelled.
