A conventional, i.e. conforming, loan requires 25% down on (non-owner-occupied) multifamily property per Fannie Mae requirements.

If not, it would be considered as "non-conforming" and difficult (if not impossible) to have insured.  

There is nothing that offsets the potential losses of running a business out of unpermitted, non-conforming residential construction.

You are conflating a skin color, with a political ideology, with the malicious intent to infer a racial bias if one is of nationalist leanings, to than label those who don't conform with your ideas, agenda and leanings, as that which they are NOT, racists. 

For us, we choose to use month-to-month rental agreements and can exercise 3-day pay or quit, 10-day non conformance, or 20-day no cause notices to terminate the tenancy if we need to.

For those who don't know, the anti-flipping rule affects you if your buyer needs to qualify for an FHA conforming mortgage, as opposed to a conventional mortgage.  

One of the motivational speeches I listen to on Spotify (Fearless Motivation) said it best: "I refuse to conform to what OTHERS want for me, what others believe I should do with MY LIFE.

Square footage plumbing, electrical, stairs all need to conform with local codes and tiny homes fall primarily under the category of a RV since they do not meet conventional codes.

I would be concerned about liability of listing something as a bedroom that does not conform to code. 

This is really conformation of my gut instinct.
