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?
