I have offered several times to bring him food, medicine, or teas, checking in on him etc.

No ACH transfers, no checks, no venmo, wire only for the most part these days.

Choose a self-directed Solo 401k provider which allows you to open the account for your Solo 401k at the bank or brokerage of your choice where you will have direct checkbook control.While what is best will depend on your objective, here are some considerations:If you want access to bank checks, a debit card and/or the ability to ACH funds out, you will need a bank, credit union etc. rather than a brokerage.

I think ACH is the best option, tied directly to property management software for tracking.

Tenants use ACH, Zelle (supported by all the major banks) or they deposit directly into my bank account.

Sounds like this project might be a head ache, though!

Given where technology is today there's no reason not to do this online.Things like a direct ACH or using some of the services others have cited in this thread allows you to set up something automated - the number 1 reason for late payment is simply "I forgot" and you can eliminate this easily.DM me if you want some more options!

The beauty of the ACH system is, I can run a local account from where I live now and have my other accounts (trading, auto pays, auto deposits etc.) funnel money into my new account and leave enough money in my previous accounts to pay what is needed through my auto pay accounts now. 

Currently I work in medicine but I am looking to expand into the real estate investing world!
