They survive "donation to donation".

The reason for @Jay Hinrichs response is that PMC's with under 300-400 doors are usually not set up as companies that can survive the owner removing themselves from the business.

I would just make sureyour PSA contains a clause in it dictating that the contract survives death and in the event of death, the estate will be required to finalize the transaction.

Quote from @Theresa Harris: Quote from @Esh Michael: What I feel sad is because of this couple being elderly, I have never questioned them. 

First question here is, could the sheriff's deed survive the foreclosure sale (at the county steps)What is more interesting is that the new owner (who bought the house from the sheriff's sale) has a quit claim deed a few months after the sale was conducted from the previous owner (the one is about to be foreclosed on) Second question, what the quit claim deed is for?

Used seller financing to buy runway to survive low rents while units turned over.

Do the surviving partners get that investors shares or do they have to deal with relatives that may be ignorant and/or greedy?

@Theresa Harris thanks for your help, I’ll be sure to make room for any additional expenses 

Greg you are still here, you survived missing that deal.
