Question about Co-Op Financials

Just that the co-op itself owns the unsold shares, instead of a sponsor. How the co-op came to own them, we don't know. Could be the sponsor went bust.

The co-op has been selling the shares as the apartments are vacated, just as a sponsor would.

Somewhere in the financials the difference (good or bad) between rents received and the maintenance will be spelled out.

My co-op owns the shares for one apartment, bought from the sponsor for peanuts, and makes a pretty good ROI by renting it out.

You need to understand whther these apartments have a negative or positive cash flow. If all occuppied by little old ladies protected by rent control paying $200/month could be problem.
