Like-Kind Property, Explained

Real property is like-kind to other real property based on its nature or character, not its grade, quality, or use category. A Hillsboro industrial building, a Beaverton apartment complex, and a stretch of unimproved land in Washington County are all like-kind to one another under the statute, because the relevant comparison is real property to real property, not warehouse to warehouse. This is a far broader standard than most first-time exchangers expect, and it's the reason a single exchange can move an investor across property classes entirely without any special approval or additional filing.

The qualifying test that actually matters is how the property was held: both the relinquished and replacement properties must be held for productive use in a trade or business, or for investment. A rental duplex, a leased retail strip, and raw land held for appreciation can all satisfy this test, while a property purchased purely for quick resale, sometimes called dealer property, generally cannot, because it was never held for investment in the first place. The holding period and the owner's intent at acquisition both factor into this analysis, which is why a property flipped within months of purchase draws more scrutiny than one held for years before the exchange.

Before 2018, like-kind exchanges could include certain personal property, equipment, vehicles, and similar tangible assets alongside real estate. The Tax Cuts and Jobs Act eliminated that entirely, and exchanges completed after 2017 qualify only for real property. Investors accustomed to older rules sometimes still assume equipment or fixtures sold alongside a building can ride along in the exchange, which is no longer accurate and can create an unexpected boot problem if those items are priced separately in a purchase agreement. A purchase contract that lumps a walk-in cooler, signage, or specialized equipment into the total property price without breaking out its value can inadvertently push a portion of proceeds into boot at closing.

A primary residence has never qualified for 1031 treatment, since it isn't held for investment or business use, though a separate exclusion under a different code section can shelter gain on a primary home sale. Property held primarily for resale, foreign real estate exchanged for domestic real estate, and partnership interests also fall outside the like-kind definition, regardless of how the underlying asset is described. A property that mixes personal and rental use, such as a vacation home occasionally rented out, requires its own separate analysis of how much of the holding period was genuinely investment use before it can be treated as qualifying.

Because the test is use rather than category, an investor can relinquish a Portland multifamily property and acquire a self-storage facility, a medical office building, or a triple-net retail pad in the same exchange, as long as both ends of the trade were held for investment or business purposes. This flexibility is what allows an investor to shift strategy, from active management to a more passive net-lease structure, without giving up deferral in the process. It also means an investor exiting a management-intensive asset class doesn't need to stay in that same category to keep the tax benefit, which is often the actual motivation behind the trade in the first place. An owner tired of tenant turnover in a multifamily portfolio, for instance, can move into a single-tenant net-lease property with far less hands-on management and still defer the full gain.
