1. Keeping the life insurance I had when I was younger. Generally speaking, we are all more agile and healthier at 20-30 years old than we are at 40 and over. Buying life insurance at an older age is more expensive. I realized that if I had retained the whole life insurance, I could have locked it in at the former premium.
2. Buying whole life is better than term. At end of term, one is older and life insurance becomes more expensive. Exception is only if one dies before the term life ends.
3. Auto insurance is higher for a leased or financed car than for a car bought outright or owned free and clear. This is one of the reasons people talk about preferring to buy used cars.
4. You get a better (I hate to use the word “cheaper”) rate/premium having the same insurance company for multiple cars, as well as using the same insurance company for your other needs; for example, home, renters, personal, life, etc. It’s called bundling.
5. That auto insurance companies can use your no-fault auto claims as a potential negligence on your part and raise your premium.
6. In insuring personal items, keep detailed information and receipt of valuables, as well as take photographs. This will help in case of loss.
7. Having a fireproof safe box is a good investment.
8. Staying with the same phone company is good. You can lock-in the plan/price you initially got if your needs remain unchanged.
9. The essence of having insurance for cellphones, especially when new. The concept is similar to any other insurance, but not necessarily worth it after 2-4 years of owning the phone.
10. Your good, and long, driving record can get you discounts off your auto premium.

The above are based on my experiences. Insurance companies’ policies do vary. As always, please do your due diligence (research, compare premiums, and ask questions) before purchasing any type of insurance.
Have a financially-wise week.
