If anyone has had experience being in such a situation, or knows of agent / PM / contractor contacts / references (or are yourself a RE / PM) who would be able to help pull off such an operation, or would be willing to partner with me in some capacity, please let me know.

I post this information in my individual capacity as a forum member, not in my trade name.

Assuming the nursing home residential does not have capacity to enter in agreement for sale, then you need to find the agent appointed under the power of attorney to sell the property now. 

I lived there for a long time, but was never involved in real estate in any capacity.

I'm always wanting to talk shop with people in the business that are motivated to do the business and move forward, in whatever capacity they choose to invest. 

Also, don't forget that they need sufficient mental capacity to transfer title when the time does come to sell.In the meantime, I'd buy the other half with seller financing or swap other property or assets for the equity.

If the heirs did not have the capacity to refinance it and retain the property, or the ability to sell to realize a profit after paying off the reverse mortgage, there likely is not a great opportunity for you here.

I am already investing to my maximum capacity but I need my bookkeeping to keep up with my actions. 

Work with everyone to some capacity but know who your A players are, your B players and those that are C.

They even made me hire an engineer to draw plans on the extra required capacity!
