I would do cash, wire, bill pay from bank to bank or ACH to get the money. 

In other words "Create an App for property management Lease Tracking" or "Create an App where my tenants can pay online by Card or ACH"Once AI builds these Apps for you, you can further customize by saying "Add the ability to keep track of my tenants' vehicle information"The final piece of the puzzle is finding a local handyman to serve as your "eyes-and-ears" on the ground.Build your system specifically for your situation, it will be cost effective and allow you to scale in the future.Hope this helpsGeorge 

Uses - Tenant application and screening (application, credit check, income verification, background check), once I verify a tenant's landlord references and employment references which are collected through the application and they've been approved and signed a lease, I use RentRedi to collect rent via ACH transfer.

We use Zillow to avertise, MySmartMove (Transunion) for background checks, Google sheets of course, bookkeeping  is completely outsourced and they use Quickbooks (I died on that hill more than once, best decision ever to outsource), for communication a seperate cell phone and it's mostly text messages, rent collection via my bank (ACH), and maintennace in a spreadsheet (how much maintenance are you planning on doing??)

I think the lack of professionalism is due to it being a career with a very low barrier to entry (a few weeks of an online course, versus years of schooling required for other professions such as finance, engineering, and medicine).

I know plenty of great borrowers who, by no fault of their own, have a late payment show up on their credit because their ACH failed to pull and they didn’t catch it in time.

Cash is digital too with the use of credit/debit cards or ach. 

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).

Norada’s promissory notes generate predictable monthly passive income transferred to the investor’s funding account via ACH,” ( Link ).Santarelli confirms these fixed, double digit returns in a detailed YouTube video presentation (Link, at 35:08).

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