Also wanted to mention that the tenants are already paying via ACH deposit.

There are a variety of options regarding auto pay and tenant initiated payment via ACH.  

Our owners never receive one document in paper it is all electronic in their owner portal, and our tenants hardly come in the office because they of new technology which allows tenants to pay online with an ACH-E Check or Credit card or they can pay their rent at 7-11 or Ace Cash express.  

If your account gets compromised it could create a ripple effect account into your checking account causing checks to bounce, ACH payments to be returned etc.  

It is free to the landlord and free to the tenant as long as they use the ACH option.

It isn't "hard" in the way construction or medicine is hard, but you will have time when it drains you.  

Exercise is the best medicine.

With that I signed up for Quickbooks payment processing and accept ACH/Electronic Checks.

You would have far to many specialist would not work.Think of a Doctor... they have to know all about medicine then they can go into a specialty that may or may not ever involved what they learned in med school.Same thing in my mind..

I am looking to see what services are available that will automatically take the tenants rent payment from their checking/savings account (ACH) every month.
