The other thing I need to mention is that, income-wise, she's pretty well covered. Between Social Security and two pensions, her take-home is as much as mine; but instead of carrying four passengers, her plane is carrying just one. So month-to-month, fine.
This is what I had in mind:
Steady income stream: check (pension and Social Security would cover monthly expenses for some years to come).
Housing: check (the sale of the home would provide enough for moving expenses, transition costs, and the full purchase price of a condo in a 55+ community, which was her goal).
Back-up savings for supplemental expenses: check (with a suplus coming from the home sale along with current savings, she'd be able to add $10k to her income for 5-10 years, no problem).
In September of 2007, I read a post on SmartMoney called "A League of Their Own" about Harvard's and Yale's endowment funds. Both were doing extremely well, and the author of the article proposes how one might replicate their strategy. I'd been buying ETFs for years with my own but never had seen anything that laid out a work plan for the indefinite future so clearly. This is what their portfolios look like:
So now I set about figuring out how to use James Stewart's ETF model for a retirement account.
