Most common scenario I see is "should I sell?"

There is an HOA.We have been working with the developer to make the unit ADA compliant, and the only way to do so was to add a door from the commercial unit into the common entry/lobby, as there is an ADA compliant ramp there. 

I'm not sure I would get to cute trying to squeeze every time out of it now with a lease that might cause you issues in the future, but the scenario you describe is common and probably smart. 

If you're in the LA area, it's definitely very common.

It isn't like this a condominium where assessments are paying for common parts of the building like the roof, etc.Prior to this, I didn't have much experience serving on an HOA board and have therefore relied on the management company for their opinion on certain decisions. 

We all have a common reason for being in the room or on the online call. 

Hard money is pretty common.

@Jason Sung Yes, this is common.

It is common for investors to bring in additional signers, often referred to as credit enhancement.

Whereas if you and the other investors held ownership as TICs (Tenants in common) then you could sell your portion and do a 1031 of your portion while others did something else.
