Replacement property rules

The replacement property is the whole point of a 1031 exchange, and the rules about what qualifies are a mix of surprisingly generous and strictly enforced. Like-kind is broad enough that you can swap almost any investment real estate for almost any other. But three requirements, held for investment, equal or greater value, and the same taxpayer, are where exchanges are won or lost. Get the replacement wrong on any of them and the deferral fails.

Like-kind is broad, with hard edges

For real estate, like-kind is far more permissive than the phrase suggests. Any real property held for investment or business use is generally like-kind to any other such real property. You can exchange a rental house for an office building, raw land for an apartment complex, a warehouse for farmland, a retail strip for a self-storage facility. The type, quality, and use of the real estate do not have to match; investment real estate is investment real estate.

The hard edges: it must be real property, since the 2017 tax law limited 1031 to real property only, so equipment, vehicles, and other personal property no longer qualify. It must be within the United States; US property is not like-kind to foreign property, so you cannot exchange a US rental for one abroad and defer. And it cannot be property held primarily for resale, dealer or flip property, which is inventory, not investment. Those edges aside, the like-kind universe for real estate is enormous.

Almost any US investment real estate is like-kind to any other, but it must be real property, located in the US, and not held for resale.

Held for investment: the intent requirement

The replacement must be held for productive use in a trade or business or for investment, the same qualified-use test that governs the property you sold. This is an intent requirement, and it is where the vacation-home and quick-flip problems live. Buy a replacement intending to move into it immediately, or to flip it right away, and it was not held for investment, which can disqualify the exchange.

The code sets no minimum holding period, but time is the main evidence of intent. The longer you hold and rent the replacement as an investment, the stronger your position. Converting it to personal use too soon, or selling it too fast, invites the IRS to argue you never held it for investment. This is the same intent thread that runs through the vacation homes safe harbor and the partnership drop and swap rules: the tax benefit depends on genuine investment intent, held long enough to be believed.

The replacement must be genuinely held for investment, and while there is no fixed minimum holding period, holding and renting it long enough is the main proof of that intent.

Equal or greater, and the same taxpayer

Two more requirements finish the picture. To defer all your gain, the replacement must be equal or greater in value, and, as the financing rules cover, carry equal or greater debt, with any shortfall taxable as boot. Buy down in value and you have a partial exchange and a tax bill.

And the same-taxpayer rule: the party that sold the relinquished property must be the party that buys the replacement. If you sold as an individual, you buy as an individual; if your LLC sold, your LLC buys. You cannot sell in your name and take title to the replacement in a different entity, or add a partner on the replacement side, without risking the exchange, because the taxpayer changed. A disregarded single-member LLC is treated as its owner, so selling personally and buying through your own single-member LLC generally works, but a genuinely different taxpayer breaks the chain.

The replacement must be equal or greater in value and debt, and must be acquired by the same taxpayer who sold, so the selling and buying party cannot change mid-exchange.

The bottom line

• Almost any US investment real estate is like-kind to any other, across type and use.
• The replacement must be real property, in the US, and not held for resale.
• It must be genuinely held for investment, with holding time the main proof of intent.
• It must be equal or greater in value and debt, or the shortfall is taxable boot.
• The same taxpayer that sold must buy, so the party cannot change mid-exchange.
