Why do you Exclude Unrealized gains from the increased value in a home before it is sold in gross income?

Unrealized gains on a home reflect an increase in value that has not yet been actualized through a sale, meaning the homeowner has not yet received any cash or tangible benefit from that increase. Tax laws typically exclude these gains from gross income to avoid taxing individuals on hypothetical profits that are not yet realized. This approach ensures that taxpayers are only taxed on actual transactions and income, promoting fairness and providing clarity in income reporting.
