Do you have control on the management group/rent price? 

Placing your own tenant takes longer (usually 3-4 months with inspections), but it gives you full control over who lives in your property, which is a huge plus in my book.

You can make more money if you have full control, but your time needs to be considered. 

Condo's are ill advised for investments because you possess far less control.

I'm sure you and I both understand that as flippers, having control over the construction cannot be stressed enough.

@Dylan Jeluso, where are you feeling you don't have control?  

Though fee schedules vary by company, generally speaking, you'll pay more up front for checkbook control and less over time, since the full custodial companies will have transaction fees not to mention the red tape of going through the custodian for all transactions. 

They cannot arbitrarily make wild gambles because they feel like it - they have to operate within established risk parameters that are approved by several regulatory bodies and internal controls.

This implies residential units can be built at lower costs than ADU additions and provide better return. 11) adding an ADU to SFH can make the SFH fall under rent control.
