Does any of the coaches provide any of the following?

Maybe they bring the experience and provide the funds.I don't like any of your options based on I think you are too new to investing in real estate to take on any of those.

I would be very careful in working with a 1031 Exchange Qualified Intermediary that provides ("sells"0 replacement property solutions as part of their services. 

However, I believe multi family provides the best ROI and is the best way to scale.

Based on the information you've provided it seems like you might be targeting the wrong type of deal flow for your budget/risk-tolerance/area.

@Sang Kim- I am sorry to hear this....DId  any of the  paperwork provided  outline if the  6K fee  was rendable  ?   

I have used Prop wire for some skip traces, but the numbers and emails it provides were not associated with the property.

I'm struggling to understand some aspects of your response, but it provides some things to think about.

Additionally, by virtue of owning all of the units I could, with the help of an attorney, construct the bylaws in such a way to maximize value and eliminate bylaws that would be value-restrictive.I've talked to a couple of non-QM lenders who could provide financing to buyers under such a scenario, but the tricky part is appraisal value, especially in a state where, according to Redfin, no co-op's have sold in the last 5 years.If I got a couple units sold using seller-financing at $220/sqft, since there aren't any other co-op comps, would this provide a basis upon which an appraiser would provide a valuation closer to $220/sqft than $135/sqft?

They should be able to provide a market rent range.
