When and how should retired investor sell?

[Steve Hartkopf]

I "retired" 5 years ago but kept two rentals because they're in great locations, with great tenants, good (not great) cash flow and are appreciating nicely. My plan was to sell them when I turned 70, in 5 years. However, I'm exploring new exit strategies since mine results in a high tax event and, like all of you, I frickin' hate taxes. Any and all thoughts or ideas are welcome and thanks in advance for your help. 

In return for your help allow me to help for you: Note, I'm old and financially independent but I'm still learning and planning five years ahead, more actually...and so should you.
