Waive Rent for tenants and Issue Grants for private landlords to recoup lost rent

I've spoken with private landlords who are willing to waive their tenants rent if they can receive some form of compensation to cover their loss in rental payments. Example, if a landlord owns 3 properties and waives rent of $1500/mo for 3 tenants, that landlord should receive a grant from the Federal government in the amount of $4500 or have their mortgage payment in the same amount forgiven. In this scenario, the tenants rent is waived and the landlord still gets their money from the Feds. (grant, not a loan)
