My mother will be moving in with us in the near future. She's currently having issues with her right foot and is immobile right now. She is receiving physical therapy and hopefully she will improve. If she doesn't, will Medicare pay for in-home care like bathing, taking her meds, helping her use the toilet, etc. My husband and I do not want to wear ourselves out with the constant lifting that is required.
Otherwise, what your asking is private pay.
You cannot rely on what she tells you. I've had relatives with "mild" dementia that they can perform all sorts of tasks they haven't done for years. Their reality is not our reality.
Mare sure you have a defensible exit plan, one vetted by a highly qualified eldercare attorney. Removing your mother from your home once she has been a resident there may not be as simple as it sounds. Your mother will have rights under the laws of your state.
Are you not reconsidering having her live with you? The fact that you realize that you can't do the physical work yourselves, but have not made a plan for how her personal care will be managed is pretty shocking.
AND then there's the fact that she has narcissistic tendencies?
This is a recipe for disaster.

When you say immobile, do you mean that she can’t transfer to a wheelchair or commode? It will take two people to lift her perhaps with a hoyer hydraulic lift to transfer, plus knowledge of how to do a bed roll to diaper her every couple hours.
