I'm considering moving my father from my memory care center to my home. What action should I take first?

A friend of mine had a loved one in memory care and it wasn't the right fit. She took her out and into a Board and Care home which is smaller and gives her what she needs. Her loved one is doing better, thank G-d.
Maybe that can help you as well.

Dementia individuals are full time care. It will be difficult to give attention to both children and your father, not to mention taking care of yourself.
You can hire a professional caregiver to help him. But there is also the issue of letting frustration into your home, when your dad becomes irritable and frustrates everyone. Either you or the caregiver you hire would need to handle that.

Either try to improve where he is now, or look into another memory care, or board and care

Wish you all the best

It's a nice wish. To care for your Father. Coming from a loving heart wanting to provide him better care.

But put your common sense hat on for a minute - Do you think one person can provide better care than a team of staff?

Why not investigate how to get him better care where he is? Talk to management, hire him a personal aide? Talk to his Doctor. Get a realistic view of his current status. Alz is progressive. Don't be in denial he will return to his old self.

Your profile says you have 2 children at home. Are you planning to abandon their care to care for your Father?

Going by most comments on a situation like this, what you need to do first is to have a brain scan yourself. Or are you expecting that your father’s ‘rapid decline’ was due to poor care and will be reversed promptly in your home? Have you consulted his doctors? What are your plans if it doesn’t work well?

Jewelzrube, before a memory care facility will take a new resident they make sure it is memory care that that person needs. Apparently they felt that was the case with your Dad. With memory care, it now takes a village to care for that person.

If you plan to bring Dad home, remember he will also be limited to his visits and his outings, that won't change until covid-19 is wiped off the map.

Will you have a "village" set up for his care? If not, will you be able to do the work of 3-full time shifts every day for 168 hours a week? https://www.agingcare.com/topics/29/caregiving/articles

You will need to set up your home similar to that of Memory Care. Such as placing locks on the outside doors that would be complex for your Dad to use, but not for anyone else. Some folks with Dementia try to go outside in the middle of the night. My Dad was trying to do that when he was in senior facility, Independent Living. Dad loved it there, so many people closer to his age to talk.

Please note that close to 40% of family caregivers die leaving behind the person they were caring, those are not good odds. Then what? Someone would need to place your Dad back into Memory Care.

You have so much to think about BEFORE bringing Dad to your home from Memory Care.

This certainly is your choice to do. There is no action to take other than to move your father into your own care. If you wish to charge him "room and board and care costs, supplies and etc." then you should attend a lawyer to make a care contract so that this payment doesn't count against his assets as "gifting" should he have to move back to care for any reason. It is also reportable as income to the IRS in most instances; an elder law attorney will guide you in this. Your father's assets will pay for this. And it is your Father's assets you will be dependent on now for his care. No medicaid monthly payments will follow him to an in home situation; what is available to him in terms of assistance will be very very limited after this move.
I would attend the consult with an attorney before any move.
I assume you are POA. Keep careful records of all costs, expenditures, and etc.
And of course, firstly and most crucial, be certain that you wish to take this on. If you have been on the Forum site for any amount of time you will see how very difficult this care is, how demanding, and etc.
Wishing you good luck.
