Ed, as a prospect I have looked at many contracts. I have yet to see one that "promises" something in case one runs out of money. The usual statements sound like: " The determination of eligibility, type, and amount of financial assistance is within the sole discretion of (CCRC name) and subject to the limits of (CCRC name) financial capacity, in its sole discretion. (CCRC name) is under no legal obligation to extend financial assistance to You and has the right to terminate this Agreement if you cannot satisfy Your financial obligations".
In addition, even for evaluation of eligibility for any assistance, the resident has to prove a list of things and if he/she is qualified, then he/she might be asked to move to a smaller residence and if the contract has any refund ability, the aid comes from there.
Based on what I have seen, I would not call what they MIGHT offer "insurance", it is more like charity....
Did you see any contract which guarantees financial assistance in case someone runs out of money?
