Having a nurse come into your home is expensive. We are running into this same situation. With the wandering risk the nicer homes are private pay and work minimally with medicare/medicaid. You are not alone - our next step is a nursing home as well - they all look the same after you see so many.
My advice - keep reaching out - rather than visiting get feedback and set up a list of questions to ask and keep notes. It may be an all out home blitz, however it is worth it when you find the right one.
Hang in there!
