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?

That would help me save taxes on the commission. 

I would recommend reaching out to @Denver McClure as he may be able to help with a non-conventional loan

Plenty exist for private lenders (which is what seller financing is) and can track payments and am tables and also do automatic electronic withdrawal (ACH debit) which helps improve the likelihood of getting paid promptly each month.

Happy to chat more if it would help. 

If you need any help in the area from pictures of home, to items being valued and or my experience how to get rid of them from estate sale to auction to donation.

I think house-hacking is a great idea and I would be more than happy to help you with the financing.

A Title Company can distribute the proceeds based on the agreement, and consulting a CPA will help calculate tax liabilities and explore strategies like a 1031 exchange to minimize taxes.

Thank you Brandon for reaching out, I appreciate your help

The flat fee buyer agency fee reduces the amount of the buyer credit/refund, generally by $6,000 (although options range from $999 to $8999, depending on how much help the buyer wants from the agent).
