The other precedent is that to evict a tenant, the landlord has to take them to court. This could take months, maybe years now for their court date. In the meantime the tenant, once served with notice, could legally live there rent free. But if the courts order it, they could get socked big time. And it’s still a while before the landlord sees a penny. Yes, the courts tend to favor the tenants, but that still doesn’t mean they can abuse the system.
Still, the longer the virus goes on, the more landlord/tenant courts will get backed up.
