What a 1031 exchange is, and three things it is not
A 1031 exchange can defer tax on investment property you trade forward. It isn't tax-free, isn't for your house, and can't be arranged after the sale.

Most people have heard of a 1031 exchange. Fewer could say what it does, and fewer still know the ways it goes wrong. Here is the plain version.
What it is
When you sell an investment property for more than you've got in it, the gain is taxable. Section 1031 of the tax code offers a way to put that bill off. If you trade the property for other real estate of like kind, and the deal is structured to qualify, the gain can be deferred instead of paid now.
"Like kind" is broader than it sounds. It doesn't mean a duplex for a duplex. Land can go into a rental, a rental into a commercial building, one property into two. What matters is that the property you give up and the property you receive are both held for business or investment.
In practice, very few of these are two people handing each other deeds. Usually you sell, a third party holds the money, and that money buys the replacement property. It's still called an exchange, because on paper it is one.
That's the whole idea: you trade what you have for what you want, and the tax follows you forward instead of coming due at the closing table.
Whether your particular deal qualifies is a question for your own CPA or tax attorney. Everything below is background for that conversation, not a substitute for it.
It is not tax-free
This is the one most people get wrong. A 1031 exchange defers the gain. It does not erase it. The IRS says it plainly: the deferred gain is tax-deferred, "but it is not tax-free."
Your old basis carries into the new property. Sell the replacement outright someday, and the deferred gain is still there waiting. Some owners exchange forward again and again for exactly that reason. How that plays out over a lifetime, and in an estate, is your advisor's to explain.
It's also rarely all-or-nothing. If you come out of the exchange with cash or other property that isn't like kind, that part can be taxable even when the rest qualifies. Taking a little off the table has a cost, and it's worth knowing the size of it before you decide.
It is not for your house
The property has to be held for business or investment. The IRS is specific that a primary residence, a second home or a vacation home used mainly for personal purposes doesn't qualify.
The harder cases sit in between: the house you lived in and then rented out, the lake place you rent a few weeks a year, the lot you bought to build on and resell. Those turn on facts and on how the property has been used, and they're exactly the kind of thing to put in front of your advisor before you list anything.
It is not something you arrange after the check clears
This is the expensive one. If you sell, take the money, and then decide to do an exchange, it is usually too late. The IRS warns that taking control of the proceeds before the exchange is complete may disqualify the entire transaction.
So the structure comes first. Typically a qualified intermediary holds the sale proceeds so you never touch them, and you cannot act as your own. That has to be arranged before the sale closes, not after.
Then the clock starts. From the day you sell, you have 45 days to identify possible replacement properties in writing, and the exchange has to be finished within 180 days, or by your tax return's due date for that year if that comes first. Those deadlines don't move because the market is slow.
The money has to land somewhere, and it has a deadline.
Why an exchange room hears 1031 money differently
That clock is why cash from a 1031 sale reads differently on a board than ordinary cash.
Ordinary cash can wait for the right deal. Exchange funds can't wait forever. The person holding them needs replacement property, of the right kind, identified inside the window. That makes them one of the most motivated parties in any room, and it makes owners of investment property the people they most need to meet.
It also changes what a trade can look like. Someone with land that pays nothing and someone with exchange money that has to be placed are not a buyer and a seller haggling over price. They are two parties trading benefits: one gets a way out of a holding that costs taxes every year, the other gets a qualifying place to land. When it's structured well, it creates benefits for all parties involved, and each leg still closes with the parties' own attorney, CPA and lender.
If you're sitting on an investment property with a large gain, or you already have exchange funds and a date circled, the time to think about it is before the deadline, not near the end of it.
Where to talk it through
GEMS meets the first Thursday of every month, 9 AM to noon, at Trailblazer Brokerage in Greenville. Owners bring property, cash, notes and opportunities, and the room looks for ways to fit them together. Your first two sessions are free.
Bring the question. Leave the answer to your own advisor.
