I am 54 and my wife is 57. We own our home outright. We have $1.6M in IRAs/401(k)s and $1M in non-retirement funds. About $2M of the total is in the stock market via mutual funds, individual stocks, and ETFs. The rest in in cash and bonds. We have no kids and no debt. We will not have any pensions and will need to buy our own health insurance until age 65 when I stop working. We will both have access to Social Security. We are both in very good health and may very well live to age 90. So, can I retire now? My wife would continue to work parttime but she will only bring in about $20K/yr gross - she is self-employed. Any thoughts would be appreciated.
