This is only my opinion. A reverse mortgage is meant to help you as the homeowner and I believe will pay you a monthly income and not a lump sum amount. If your home is paid for you can change the deed to a 'Transfer on Death' deed and have the house transfer to your sons upon your death and this will also bypass probate in most states. Whether you are in bad health or not it appears that your sons will not be able to help you financially if needed and I would reconsider jeopardizing your own financial security. Don't sell yourself short.
