So if your interest payment is $1000 then the servicer automatically ACH debits your account that plus the servicing fee (assuming you set up automatic payments as @Christian Ehlers suggests).

They get an ACH from my tenant in their account same day, but won't do the same into my account.

It comes with ATM/VISA (Debit) cards, checks, online bill-pay, mobile banking, mobile deposits, direct deposit, ACH transferring between accounts, etc.

I'm not sure what bookkeeping software you use, but QBO has a payments feature built in where you can collect on invoices using credit card or ACH Bank draft, and it deposits it right into your bank account.

Which ok, I get it, ACH cost money, BUT, RentRedi does not give the landlord the option to pay that. 

What area of medicine are you in?

FYI: most PMC software includes electronic payments via ACH - for which banks charge fees past a certain amount of transactions.

If you have a tenant that simply forgets to pay rent, set them up on ACH autopay with the bank. 

When the mortgage market cools down they’re selling oil and gas partnerships; then on to time shares, ACH loans, and auto repair franchises, with a pit stop for a try at multi level marketing.
