The "6-year rule" for Capital Gains Tax (CGT) in Australia allows you to treat a former main residence as tax-exempt for up to six years after you move out, even if you rent it out, enabling you to avoid CGT on any growth during that period.

If you rent it out for longer than six years, only the portion of the gain after the six-year mark becomes taxable.

The primary "one-time" capital gains exemption in the U.S. allows single filers to exclude up to $250,000 (or $500,000 for married couples filing jointly) of profit from selling their main home, provided they've owned and lived in it for at least two of the last five years before the sale. While it's often called a one-time exclusion, you can use it multiple times, but you must wait two years before claiming it again on another property.

With an investment that has performed strongly, you might, for example, sell a portion at the end of 2025, another part in 2026 and the remainder early in 2027. That way, you complete the sale in a little over 12 months while spreading potential capital gains over three tax calendar years.
