Seller Not disclosing tenants behind on rent

[Mark Panno]

Is it illegal to sell a rented property(4 plex in this case) and not disclose that a tenant is behind on rent?   

The rent was prorated at closing as if it was paid for the month of December.

Anyone have experience with this?

I have no comment on the "legality" of that. But from a buyer's perspective - it's hard to imagine closing on a 4-plex without asking to see a rent roll report and all other financials (for the past 12 months at minimum) as part of normal due diligence.
