I would double check with a real estate attorney who understands structures for rental properties.

I can assure you in in upscale and luxury, having a place to put clothing - be in nice closet organizers w drawers or a dresser, I think you're probably right.

Once you have that, file articles of organization with the secretary of state.

And that all depends on how you have structured your investments.

Most jurisdiction do not allow them to be rented short term (<30 days).I believe some jurisdictions will let you convert existing structure to the ADU, but I do not believe this is statewide and is probably a minority of jurisdictions.  

I plan on asking the tenant below soon if she notices large differences from the full carpet that was installed before.

The reasons you stated, plus the fact that mortgages are full recourse in Canada, seem to point to the fact that note investing is not a thing in Canada.I guess I’ll have to buy in the US in that case.

And the ones that are having to make emergency capital calls now (and are in trouble) are almost universally the ones that were structured non-converatively.

During the time I was in school I worked full time as a salesman, and currently sales manager for a moving/junk removal company in Macomb, MI. 

The use case will likely dictate the source/structure
