Reverse mortgage is an option. I have looked into it for my FIL. The thing is they won't give you the total amount of the market value and they only "loan" you port of it. e.g., out of 800,000, they only loan you 300,000 or less. There is a website that can do the calculation for you - please google for it. The other minus thing is you need to sell it ASAP after the owner who gets the reverse mortgage (your Dad) moves out of the house. To complicate it further, revsere mortgage is for the owner himself strictly speaking. I am not sure how it applies to his wife although the money will help but what about him? You need to worry about him. Also, with reverse mortgage, you can either hire caregiver or you or your Dad needs to care for her personally. I suspect you need to hire someone with that sort of money. Know that reverse mortgage is for staying in the house - the money is not for the owner to move out, but it is useful for his wife.   Just my 2 cents, Nina
