I do not know much about Reverse Mortgages. I did look at a house for sale about 16 years ago. The owner had died, and the estate had 6 months to cover the amount already paid out plus interest or lose the home to foreclosure. From recent experience, that is barely enough time to get an estate organized, the home cleared out, listed & sold. The realtor was about to lose her commission if it wasn't sold soon. The house did sell at a deep discount. I'm sure the beneficiaries were not happy campers, for sure.
For someone with no children, a reverse mortgage might make sense. Why not?
