As someone currently working through growing pains in their business, it is appreciated. 

They're all nice people at the company, I just think they're going through major growing pains and unfortunately old owners are feeling the brunt of it. 

First, ATG is not law but merely an administrative guidance.

I'm a 401k administrator and yes, you can use an S Corp to fund a Solo 401k (can use Schedule C, w-2, K-1 as a partnership, or 1099 income towards a 401k...). 

It is a bit of a pain to go through the approval process to become an allowed advertisor, so it may not be worth it for a single unit owner.  

This has a lot of administrative overhead, the LLCs being disregarded entities may pierce the corporate veil.

I’m seeking advice from any investors who have dealt with the pain of owning a co-op in NYC.

This is mainly due to the administrative hassle that comes with handling deposits.

Having it in both FL (my domicile) and CT (property location), created double the work and fees in both states.From what I can tell this isn't the right entity structure anyway, so I can imagine it was a pain with many extra costs! 

So our hopes at reconsideration based on on the historical permit records are slim to none.So it looks like our only move here is to prove that the coach house has been existing as residential for at least 20 years and get an administrative adjustment.
