An investor sells an apartment building and immediately channels the proceeds into a larger commercial property. That move can qualify as a 1031 exchange. Under Section 1031 of the tax code, the gain is deferred rather than taxed at the time of sale, provided strict rules are followed.

Both the relinquished and replacement properties must be held for investment or business use. The investor has 45 days to identify potential replacements and 180 days to close. Like-kind is interpreted broadly for real estate, so an office building can be exchanged for raw land or a retail center. A qualified intermediary must hold the funds; the seller cannot touch the money.

Timing and documentation are unforgiving. Miss a deadline or mix personal-use property into the deal and the deferral disappears. Many investors use the strategy to scale portfolios without bleeding cash to taxes at each step. The tax is postponed, not erased; it surfaces when the final property is sold without another exchange.

• Defers capital-gains tax on investment property sales
• Requires like-kind real estate and strict timelines
• Must use a qualified intermediary
• Allows portfolio growth while preserving equity
