Seems to me cohesive set of laws and rules regarding this activity would benefit  both the public and those that want to engage in the activity.  

Follow up re-engagement and appointment setting.

If the latter, depending on the jurisdiction, YOU may need to be a licensed real estate agent/broker to engage in what’s commonly called “wholesaling” but is actually “flipping”. 

How does one define design choices, etc?

Quote from @John Underwood: You can't sell your account.You can only sell SFR properties based on comps not rental income.John, thanks for engaging.

When you go to sell the property, if you produce a certificate of inspection for the wrong number of units, buyer unless you are giving them a great deal and they will throw caution into the wind, would insist on the correct designations.

Engaging in finding renters for clients on rental properties normally isn't worth a realtor's time.  

There are some creative ways to get it from 37% to corporate tax rate of 21% but generally it's best to invest passively as the IRA is designed.  

Mixed-use properties that integrate residential units, co-working spaces, and retail areas with sustainable design elements are particularly appealing.

They taught me how to professionally engage the brokers and sellers and submit all-cash offers using THEIR cash.
