Reverse 1031 Exchange: Buy First, Sell Second

An hourglass on a calendar captures the essence of time management and urgency.

A standard 1031 exchange has one hard requirement that trips people up in a fast market: you have to sell first. But if you've found the replacement property you want and you're worried it'll be gone before you can close your current sale, a reverse exchange flips the order. You buy the replacement first, sell your original property afterward, and still defer the tax.

Why you can't just "buy first" on a normal exchange

The rule that makes a standard 1031 exchange work, never touching the sale proceeds, depends on a specific order: sell, park the money with a qualified intermediary, then buy. A reverse exchange breaks that order, so it needs its own structure to stay legal. That structure comes from Revenue Procedure 2000-37, the IRS safe harbor that makes reverse exchanges workable.

How it actually works: the exchange accommodation titleholder

You can't personally hold title to both the old and new property in the middle of an exchange without disqualifying it. So a separate company called an exchange accommodation titleholder (EAT) takes and holds title to one of the two properties, usually the new one, until your original property sells. Once that sale closes, title moves from the EAT to you and the exchange is complete.

There are two versions, depending on which property gets parked:

  • Exchange last: the EAT holds the replacement property while you sell your original. This is the more common version.
  • Exchange first: the EAT holds your original property while you close on the replacement. Used less often, usually when the replacement seller won't wait.

The same two clocks, running in reverse

The deadlines don't change. They just apply to the other side of the deal:

  • 45 days from when the EAT takes title to formally identify which property you're selling, if you have more than one candidate.
  • 180 days from when the EAT takes title to finish selling your original property and close out the exchange.

Miss either one and, just like a standard exchange, the tax deferral falls apart.

What it actually costs

Reverse exchanges cost meaningfully more than standard ones and take more work. The EAT has to actually hold and finance the parked property, which means real carrying costs (financing, insurance, property tax) on top of the intermediary's fees. Expect it to run several times the cost of a standard exchange. It's worth it when the alternative is losing a property you can't replace. It's not something to do just for convenience.

When a reverse exchange is worth the extra cost

  • You've found the right replacement property and the seller won't wait for your sale to close.
  • Good inventory is moving fast, and a standard exchange's timeline puts the deal at risk.
  • You need to lock in financing on the replacement before rates move.

When it's not

  • You have flexibility on timing and the normal sell-first order works fine.
  • The deal's numbers don't support the extra carrying costs and fees.
  • You don't have a qualified intermediary and EAT lined up yet. This has to be set up before you close on anything, not patched together afterward.

Where Winner Realty fits

The reason most investors look at a reverse exchange is that they found the right property before they were ready. We see that a lot, because our private investor marketplace, OffMarket.deals, shows buyers off-market rentals and commercial property early. If you're weighing a reverse exchange, we'll help you price both sides, line up the timeline, and get your current property sold inside the 180 days.

Frequently asked questions

Is a reverse 1031 exchange legal?

Yes. It works under the IRS's Revenue Procedure 2000-37 safe harbor, which specifically allows this structure.

How much more does a reverse exchange cost than a regular one?

Meaningfully more. The EAT has to hold and carry the parked property (financing, insurance, taxes) in addition to the intermediary's fees. Get a specific quote from your qualified intermediary before you commit.

Can I finance the property the EAT is holding?

Yes, but the financing has to be set up carefully with the intermediary to protect the exchange. Don't do this without an experienced qualified intermediary involved.

What happens if my original property doesn't sell within 180 days?

The reverse exchange fails and you lose the deferral, same as missing a deadline on a standard exchange, except now you may be holding two properties instead of one.

Do I still have to follow the identification rules?

Yes, in reverse. You have 45 days to identify which property you're selling if there's more than one candidate.

Is this the same as a 1031 into oil and gas?

No. A reverse exchange is about timing: buy before you sell. What you exchange into is a separate question. See our guide to 1031 exchanges into oil and gas.

This is general information about how reverse 1031 exchanges work, not tax advice for your specific deal. A reverse exchange has to be set up with a qualified intermediary before you close on either property. Talk to one, and to your CPA (certified public accountant), before you make an offer.
