I saw a Reddit reader say he had some sort of 4-year exclusion on home gains tax because he is in the military.
“The second rule is the military extension of the capital gains exclusion. This allows active-duty military members who are away from their property due to permanent change of station orders to extend the 60-month period up to an additional 10 years. This means that eligible military members may exclude their capital gains as long as they occupied the primary residence for two of the previous 15 years.
“There are special limitations for situations in which a homeowner moves back into a previous rental property.”
That would be yet another investment benefit that is only available on principal residences—not stocks, bonds, or even duplexes, the subject of my most recent real estate investment book.
