Here's a link to what is called Continuing Care Communities.
Continuing CareWe have two such in my small city, where they have cottages or duplexes, independent apartments, assisted living, and skilled nursing care, all with varying fees. They are both "buy-ins" with varying amounts refundable to your heirs, from $0 to about 50%. The larger the refundable amount, the more you pay upon buying-in. At least one meal is provided each day. The older one here, about 30 years, the monthly fee for ONE in a basic 2-bedroom apt is approx $1600.
A friend of mine moved into one in Springfield, MO that is set up a little differently. It's rental, rather than a buy-in. She pays so much a month for her unit, which is in a group of 8 attached. But at first she paid a non-refundable $2500 "move-in" type fee.
Three of my relatives moved into one in Wisconsin that didn't have the one-meal a day requirement, they just had special dinners on occasion. It was apartments with common areas, alert-cords in the bathrooms to pull for help, a manager and small staff. No assisted or skilled. When my aunt had to go to a nursing home, she was able to sell her apartment.
I may be ready some day, but right now I like my own cooking too much, and like keeping unconventional hours. And at times there's too much chatter about who uses rubber sheets, etc.
