Buying Underperforming Condo Complex

[Account Closed]

What have been some creative ways people have acquired condo complexes in their entirety? I'm looking at a 90 unit complex, four buildings, with multiple owners (one owner has around 55% of units, and is looking to gain sale permission from all unit owners to sell the complex. 

What options do I have to acquire the entire complex, given a discounted opportunity? (My idea is to turn the discounted PP of each unit around with better management, repairs, upgrades, etc, and sell entire complex again at 50-60k/unit spread. I've also humoured turning complex into a health care facility)
