80%? Whaaaaa? Of my family's (we own warehousing together) commercial tenants all have paid April rent. It's primarily trucking and warehousing and so they're still all working as they're considered essential.
I can understand how non-essentials aren't paying rent as they're closed down and their income is zero (though some are receiving government money) but for essential businesses all should be paying rent. It would be interesting to have an idea as to what % of commercial is presently not shut down.
