You'll probably still have to pay prepaids, but that's normal, and then you wouldn't have to tie up all your funds and then get a higher interest HELOC down the road.

Since my properties are mostly in separate LLC's, I have separate bank accounts and credit or debit cards for each company.

If you screen properly, collecting rent won't be a problem, but in my opinion even if you collect it ahead of time you shouldn't spend that money until you've earned it- what happens if they need to move out and want the prepaid rent back?

Have your credit card/debit card ready to pay the fee, and start on their website:https://www.njportal.com/DOR/BusinessFormation/CompanyInformation/BusinessName

They prepaid the months rent a few days before the fire and have a decent security deposit i'm holding.

There are retailers open on Sundays that sell money orders and accept payment via debit card/credit card, so they could still be purchased on Sundays.  

Debt wise, I currently have 1 mortgage (~$27K balance), 1 commercial loan (approx ~$42K balance), an unsecured loan ($13K balance), followed by some credit card debit totaling ~$15K.

This was going to be prepaid to me for the two weeks at the closing.

Accepting prepaid rents for 25 years will give you a heck of a tax hit in the year it is received.It would be easier to pay interest and pay that amount back as rents.

@Dawn AnastasiYou've co-mingled deposits with rents (debit to checking) and in some jurisdictions that's a no-no.
