Parents have cognitive impairment. I am their primary caregiver. They want to sell their home, build on to ours and live with us. My husband and I are willing to do this. However, if Medicaid is ever needed, will there be a penalty for money spent on addition? My Mom has moderate Alzheimer's and Dad has the start of dementia. They are now living in their own home but I clean, cook, pay bills, provide transportion and go to all doctor's visits and husband takes care of outside of house. Help. We are trying to do the right thing.
