You missed an important item: Depending on how a person does #1 or #2, it could get them: A fast-pass to the "Principles Office" for "bullying" and now there sitting in "detention".... 

I know depending on where an investor is in their fix and flip journey and the market this will vary, but Im curious because I feel like this is important when it comes to a good deal since some investors might not mind making less to have more doors. 

Those tens of billions in valuation depended on pre-fire conditions.

NOT a Quitclaim Deed, as you may often see online, because Quitclaim Deeds do not fully warrant the rights and covenants of property as does a Grant and/or Warranty (or equivalent depending on state) does.

After that, it may depend more on the workload of the inspector.

@Andreas Mathews admirable, but make sure you do some research so you understand what a PM can make.Starting your own PMC business will require 75-150 doors to make a decent living, depending on gross rents and your fee structre.Working for a SFR PMC as a PM, will require a RE license and you usually get paid a percentage of the gross rents the portfolio of owners/properties you manage generates.

Some investors are better at doing their research, financials, and taxes than others - it depends on the investor....

Your account structure depends on your goals for growth and if you plan to self-manage or hire a PM.

Short answer: Yes, laundromats can be profitable, but profitability depends on a few factors.
