Purchasing a long-term care policy for your parents can be a wonderful gift if presented in the right manner. If all the siblings pay the premium together, the cost of the policy over 20 years is usually less than what a few years of long term care would cost out of pocket. It doesn't erase the issue but it can ease the impact. Work with a financial advisor who is familiar with the various policies. Laws vary state by state.
Coverage varies with each insurance company.
Care is a personal choice. No one wants to go to a nursing home. These are some of the basics to cover. Long-term care insurance is like any other type of insurance. If you never need it or use it, you threw away you money.
