A few questions to ask yourself
1. What was the purpose of the money put into the CD in the first place ?
2. Is that still the purpose for this money ? If so, find an appropriate institution to provide a reasonable safe return on that money (might be WAMU, might not)
3. Does your mother need any kind of life insurance policy ? Does she need long-term care insurance ? If so, then research and find out what policy she might need and find the best coverage and rates from the Insurance providers out there.
4. What are the odds that her bank, WAMU with which it made sense to have a CD parked a while back, just so happens to offer the best insurance policy that she didn’t know she needed just when her CD matures ?
