I was a tax accountant for over 30 years and there is very good advice here.
Plan a budget on what you think you need to retire and add 3% for inflation for an average of 30 years. The question is not do you have what you need to retire now. The question is do you have enough to pay all your bills 35 years from now.
Here is a trick missed by many professionals. My wife can claim 1/2 of my SS when she turns 62 allowing hers to go up 8% per year until she turns 70. At 70 she can flip from claiming 1/2 of mine to 100% of hers and gain the increase on her SS. Vice versa works also. I can claim 1/2 of hers etc.
Keep reverse mortgages in mind for later years. They can be good in the right application. Not all of them are good.
