Even in NYS it is just a moratorium on evictions...rent is still accruing, late payments and fees are still growing. 

My commercial banker is helping me apply to defer the loans, meaning the payments are deferred to the end of the 10 yr balloon note (but still accruing interest).

I know the LOC was for 61K but do not know about any interest accrued etc.

Owner shall pay Agent all management fees which would have accrued through the end of the term of the lease, or in the event of a month-to-month tenancy, all management fees which would have accrued through the expiration of the thirty (30) days following notice of termination. 

In some cases I may even be able to wave 20%-30% of the accrued payment, as long as tenant commits and is comfortable with a payment plan.If tenant is unable or unwilling to pay or negotiate, proceed with eviction and collect payments via collection agencies.

Will the mortgages accrue interest if not paid for the 3 months?

I would just advise that forbearance is not forgiveness and still accrues interest; you probably know this if you have student loans. 

They will cause the landlords temporary pain, accrue late fees and back rent, and eventually when America reopens, get evicted, sued, and have their credit ruined.In that third case, a minority of landlords are being forced to basically donate free housing to the very worst behaving tenants.

During the potential 360-day forbearance period, no fees, penalties, or interest beyond the amounts scheduled or calculated as if the borrower made timely contractual payments shall accrue on the borrower’s account.Reciprocally, servicers may not collect any such fees, penalties, or interest during this forbearance period.

When you use private or hard money to do a BRRRR deal, all these costs accrue (interest, insurance, taxes) when you are doing the rehab and unable to obtain cash flow.
