A 1031 exchange is a provision of the US tax code (Internal Revenue Code Section 1031) that allows a property seller to defer capital gains taxes on the sale of an investment property, as long as they reinvest the proceeds into another "like-kind" property within a set timeframe. The name comes from the section of the tax code; in commercial real estate, the exchange mechanism is one of the most important transaction structures in the market.
How a 1031 exchange works
When an investor sells a commercial property and realizes a capital gain, they would normally owe federal capital gains tax on that gain — potentially 20% or more on long-held assets with significant appreciation. A 1031 exchange allows them to defer that tax indefinitely by rolling the proceeds into a new investment.
The mechanics have strict rules:
Timeline. The seller has 45 days from the closing of the relinquished property to formally identify potential replacement properties. They have 180 days from that same closing to complete the purchase of at least one of those identified properties.
Like-kind property. The replacement property must be "like-kind" — in practice, this is interpreted broadly. Most commercial real estate qualifies as like-kind to most other commercial real estate. A retail building can be exchanged for an apartment building; a warehouse can be exchanged for an office building.
Equal or greater value. To defer the full gain, the replacement property must be equal to or greater in value than the relinquished property. If the exchanger buys down in value, they pay taxes on the difference (called "boot").
Qualified intermediary. The exchange must be handled through a qualified intermediary — a third-party entity that holds the sale proceeds during the exchange period. The seller cannot touch the money.
Why 1031 exchanges create motivated buyers
The 45/180-day timeline creates real urgency. A seller who closed on a property sale last month has a hard deadline on identifying replacement properties. If they can't find the right replacement property in time, they lose the tax benefit — which on a large gain can be millions of dollars.
That urgency makes 1031 exchangers among the most motivated buyers in the commercial real estate market at any given time. They're not browsing; they're actively trying to close.
For brokers, this creates a specific lead type: any recent commercial property sale where the seller is likely using a 1031 exchange is a potential motivated buyer. If you can identify those sellers and reach them during their 45-day identification window, you're talking to someone who needs to make a decision, not someone who's considering it theoretically.
How to identify likely 1031 buyers
The ACRIS database records every commercial property sale in New York City, including the sale price and the parties involved. A large sale that recently closed is a signal that the seller may be looking for replacement property.
Not every seller does a 1031. Sellers who are cashing out entirely, sellers with tax losses that offset the gain, and sellers using other tax strategies won't be in the market. But a significant portion of commercial real estate sellers — particularly those who've held property for a long time with substantial appreciation — use 1031 exchanges regularly.
Station CRM's 1031 buyer list tracks ACRIS activity daily and identifies recent sales that are likely 1031 exchange situations. The list is updated continuously and is one of the market intelligence layers built into the platform.

The tax deferral, not elimination
One clarification worth making: a 1031 exchange defers capital gains taxes, it doesn't eliminate them. When the replacement property is eventually sold — unless the investor does another 1031 exchange at that point — the deferred gain becomes taxable.
In practice, many real estate investors use 1031 exchanges repeatedly, rolling appreciation forward from one property to the next. The deferred tax becomes effectively permanent as long as the chain of exchanges continues, and at death the gain can be eliminated through the step-up in basis that heirs receive under current tax law.
This is why 1031 exchanges are such an important tool in commercial real estate — they're not a loophole so much as a deferral mechanism that investors use to compound their real estate holdings over time without the friction of paying taxes at each step.
