I have never used, but the retail landlord I used to work for uses DashComm to allow their tenants to pay rent and report sales.https://www.phillipsedison.com/neighbors/dashcommAgain, this was not rolled out when I worked there many years ago, but I know a vast majority of their tenants have escalation clauses, NNN's, some properties have utility pass throughs that vary each month, etc.I will also say, for what it is worth, they had a full AR department that would mail out statements every month to every tenant.  

When conducting a BRRRR of a property that a bank only allows a commercial mortgage on (4+ units), the ways to add value are much more straightforward than a smaller multi-family.

First, the lender will probably be willing to allow the buyer to qualify for the mortgage, at a somewhat higher interest rate.  

I buy in Birmingham where okayish properties list for 50k, can be rent ready for 2-5k, and have ARVs of 80-90k.If I can put 5k in and get the appraisal to 85k that will allow me to be front end profitable on rentals after refinance. 

The 15% return on the investment should allow you to repay the loan from the investment.

This is a house-hacking strategy that many individuals are utilizing to cover their mortgages right now.

The Housing Authority calculates what each individual tenant is able to afford based on their bedroom needs and income. 

However we have been having trouble finding a lender that is willing to allow us to get the full 80 percent loan to value in a refinance.

Tenancy in common gives more control over what happens after death, allowing you to specify beneficiaries or sell your share separately.

I expanded upon that with my own observations on how the same individuals who are teaching this are also teaching other bad business tactics and the reprecussions that will come from the way so many are being taught.
