We're both 58. I retired at 52; DW at 56. We each have a small pension and affordable retiree health insurance from former employers. We also have a rental property that generates decent cashflow, and we take dividends in cash from our taxable brokerage account. Those sources cover 65-70% of spend, which includes all ongoing, non-discretionary expenses. Beyond that, we sell equities in the taxable account, usually just for large discretionary items like travel, home improvements, or a new car. Our WR is around 2.7%.
At the moment, our plan is to defer SS and RMDs to 70, which maximizes time to convert tIRAs to Roth. In the meantime, if the taxable account starts getting uncomfortably low, or if there's a sharp market decline, we might claim DW's SS a bit early and/or cut back on discretionary spend.
We also have two possible "Plan B" items that will likely occur before 70, including a small inheritance, and proceeds from downsizing the current house, which is way too big for the two of us.
As a sidenote: Prior to age 44 or so, our taxable account consisted only of a $50K emergency fund. But this grew very rapidly over the next several years as our income was growing (including stock options and bonuses), but our expenses were flat or even down slightly as we avoided lifestyle creep and the kids both went off to college. By 52, the taxable account was almost as big as tax-deferred and the kids were on their own.
