My dad and mom lives with my sibling because mom has dementia. My dad wants to leave because he is tired of the son taking his pension money. He gives the son rent money but he keeps asking for more, his excuse is that he takes care of his mom. I want to help but don't know how.
Room and board can be factored in and then a wage for caring for Mom and Dad.
Dad has to realize the cost of care if he had to pay for it. Check with agencies in the area to what they charge an hour. Check with Assist Livings to see what the monthly cost is for the two of them. This way you can show Dad what a bargain he is getting.
It is not unreasonable for your Dad to contribute to the expenses by paying a fair share.
