What is the maximum profit per couple on a second home that can be exempt from capital gains tax?

The maximum profit per couple on a second home that can be exempt from capital gains tax is indeed not listed among the provided choices, which makes the option stating "none of the above" appropriate.

Capital gains tax exemptions typically apply to the sale of a primary residence rather than a second home. For a primary residence, the exemption allows couples to exclude up to $500,000 of gain if they meet specific ownership and use requirements. However, this exemption does not extend to second homes; therefore, any profit realized from the sale of a second home would generally be subject to capital gains tax.

Understanding these distinctions is crucial for homeowners and investors when they are planning the sale of their properties, as it impacts their tax liabilities. Thus, since the correct maximum exemption for a second home is technically zero, "none of the above" correctly identifies that the provided figures do not accurately reflect the reality of capital gains tax exemptions for second-home sales.
