My Dad has dementia and needs 24/7 care. I was a CNA for 20 years and would like to care for him in my home (with pay). What would I be paid?

He has insurance that pays over $6,000.00 a month for an extremely tiny room (twin bed, night stand, small dresser is all that fits). The food is TERRIBLE! He has never liked sing-alongs, playing games or cards, shuffle board, other group activities. He likes to work on cars and motorcycles, build houses, design things... nothing he can enjoy at all where he is. He is beyond MISERABLE!!!! I am in the process of buying a house, in which I would consider taking him in and caring for him for the rest of his life. I would make sure it was all on one floor, had easy access for a wheel chair, shower chair, had a fenced in yard that was beautifully landscaped (I'm a gardener and Interior Designer). I took care of dementia patients for 20 years, also took in my grandmother until she passed at age 105. I then took care of my mother (5 major brain aneurysms that left her paralyzed and mute with aphasia... but understanding everything) for 9 1/2 years. I literally blew through my entire life savings. Because I never got paid, I lost all that time of social security contributions so I will have to work for the rest of my life. My mother was forced to live in assisted living with me sharing the tiny room so her insurance was not voided. Living in her home that sat vacant all that time was not an option according to her insurance company so we got socked with huge taxes and upkeep for no valid reason. This would be the ideal time to take my Dad in. I cannot afford to have no income, pay for his food, his medical supplies, care, taxes, transportation, etc. like I did with my Mother. How do I go about finding out how much I would get paid to care for my Dad in my home? I would certainly give him much better care than anyone else. I live in NC.
