Most Americans live in a state where unemployment benefits is easily enough for food.
It's extremely unlikely your landlord is going to be able to rent it to someone new in the foreseeable future. Most landlords are highly leveraged and need income.
Make an offer to cut it in half and see if they bite.
They have had 0% success and the only response is really that rent is due on the first.
There will be a massive commercial real estate crisis soon.
I suspect that the managers of REITs and partnerships that own most commercial property worry that accepting lower rent would make it harder for them to delude their investors into thinking their property values haven’t tanked. “We appraise this property based on a rental income of $5k/mo, it’s just between tenants right now”
I've seen it for years: Empty shop buildings, a glut of local businesses wanting to rent them, but they are kept empty until some chain willing to pay double turns up a year later. For the landlord, it's worth waiting if that will be the outcome.
