A 1031 exchange only applies to property held for investment or business use, not a primary residence, which has its own, separate Section 121 exclusion of $250,000 ($500,000 married filing jointly) instead. 'Like-kind' is defined broadly for real estate, essentially any investment real property can be exchanged for any other, and the process runs on strict deadlines: 45 days to formally identify replacement property after closing the sale, and 180 days total to close on the replacement.

Arizona's own capital gains treatment is worth understanding on its own terms, separate from the 1031 decision entirely. Arizona allows a 25% subtraction against net long-term capital gains before applying its flat 2.5% rate, effectively taxing long-term gains at about 1.875% rather than the full 2.5%. As of January 1, 2026, this subtraction expanded to cover all long-term holdings, previously it only applied to assets acquired after December 31, 2011, meaningfully improving the state-level math for anyone selling a long-held investment property today.

Even with Arizona's relatively gentle state-level treatment, the federal side of a large gain remains the bigger number. Long-term federal capital gains rates run up to 20%, with an additional 3.8% Net Investment Income Tax applying at higher income levels, and combined with Arizona's roughly 1.875%, a $500,000 gain on an investment property can easily generate well over $100,000 in total tax if recognized outright in a single year, a substantial cost a 1031 exchange defers entirely.

A vacation home or second home doesn't automatically qualify for 1031 treatment just because it sometimes gets rented out. It generally needs to be genuinely converted to investment use, with documented rental activity, most practitioners recommend at least two years, and limited personal use, before it's treated as qualifying like-kind property rather than a personal residence.

For retirees specifically, the more common motivation for a 1031 exchange isn't avoiding taxes on a sale outright, it's trading active property management for something more passive without recognizing the gain. A triple-net lease property, where the tenant handles most maintenance and expenses directly, or a Delaware Statutory Trust (DST), a fractional, professionally managed ownership interest that still qualifies as like-kind real estate for exchange purposes, are the two most common vehicles for this. DSTs in particular reduce management responsibility to nearly zero, but they come with real tradeoffs: illiquidity, no ability to refinance or make major property decisions individually, and dependence on the sponsor's management quality.

Simply selling the property and paying the tax is still frequently the right call, particularly for a retiree who genuinely wants to exit real estate entirely and simplify their financial life. With Arizona's effective long-term rate now around 1.875%, the state-level cost of just selling is lower than many people assume, which shifts the decision more toward lifestyle and liquidity preferences than pure tax avoidance.

Estate planning changes this calculation for anyone who might not need the sale proceeds during their own lifetime. Property held until death receives a step-up in basis for heirs, meaning the deferred gain built up through one or more 1031 exchanges can be eliminated entirely rather than merely postponed, if the property (or its DST or replacement-property equivalent) is still held at death rather than sold beforehand.

If you're a landlord approaching retirement and tired of active property management, model both paths side by side: selling outright and paying Arizona's now-lower effective long-term rate plus federal tax, versus a 1031 exchange into a passive DST or triple-net property that keeps the deferral alive but trades one set of tradeoffs for another.

If your estate plan doesn't require the sale proceeds during your lifetime, weigh continuing to defer through 1031 exchanges until death, which can eliminate the built-up gain entirely for your heirs via the step-up in basis, against the value of simplifying and gaining full liquidity now.

If you own a vacation home you've occasionally rented out, don't assume it automatically qualifies for 1031 treatment, document the genuine conversion to investment use well before attempting an exchange.

• Assuming a 1031 exchange is required to avoid a large tax bill without first checking Arizona's 2026-expanded 25% long-term capital gains subtraction, which already lowers the state-level cost of simply selling.
• Trying to 1031-exchange a vacation home without first genuinely converting it to documented investment use for a meaningful period.
• Missing the strict 45-day identification and 180-day closing deadlines, which are unforgiving and not subject to extension for most circumstances.
• Not weighing DST illiquidity and loss of individual control against the appeal of eliminating property management responsibilities.
• Overlooking that continuing to defer gains through 1031 exchanges until death, rather than selling during your lifetime, can eliminate the built-up gain entirely for heirs through the step-up in basis.
