Long-term care (LTC) insurance can help protect you from the financial burden associated with needing care later in life. It's important to consider applying for LTC insurance as early as possible, since the younger you are when you apply, the lower the cost of your premiums will be. Additionally, if you wait too long, you may be declined for coverage due to age restrictions. Therefore, it's recommended to apply for LTC insurance when you are in your late 40s or early 50s, or right after you retire. This will ensure you have the best chance of being accepted and receiving the most cost-effective rates.
