Reverse 1031 Exchange: How to Buy Before You Sell

Found the perfect replacement before your sale closed? A reverse exchange lets you buy first and sell second — without losing the deferral. Here is the full mechanism, and its price.

By Jerry Baker · Updated June 2026 · 13 min read

The standard 1031 exchange assumes a tidy sequence: sell first, then buy. Real markets rarely cooperate. The ideal replacement property often surfaces before you have sold the one you own, and waiting can mean losing it. The reverse exchange exists for exactly that moment — it lets you acquire the new property first and dispose of the old one afterward, while preserving full tax deferral. It is the most powerful and the most expensive variation of the 1031, and using it well means understanding both how it works and what it costs.

Key Takeaways
  • A reverse exchange flips the order: you acquire the replacement property before selling the relinquished one.
  • Because you can't hold title to both at once, an Exchange Accommodation Titleholder (EAT) 'parks' one property under the safe harbor in IRS Revenue Procedure 2000-37.
  • The same clocks apply — 45 days to identify the property to be sold and 180 days to complete — measured from the parking date.
  • Reverse exchanges cost more and usually require cash or a cooperative lender, because the EAT, not you, holds title during the parking period.

What a reverse 1031 exchange is

A reverse 1031 exchange is a like-kind exchange completed in reverse order: you buy the replacement property first and sell the relinquished property afterward, still deferring tax under Section 1031. Everything else about the exchange — the like-kind requirement, the goal of deferring capital gains and depreciation recapture — is the same as in a standard delayed exchange. Only the sequence changes, and that single change introduces a structural problem the tax law had to solve.

The problem is ownership. Section 1031 does not permit you to own both the old and the new property at the same time and still treat the transaction as an exchange. So a reverse exchange needs a way to hold one of the two properties "off to the side" until the timing resolves. That mechanism is the parking arrangement.

How the parking structure works

In 2000 the IRS issued Revenue Procedure 2000-37, which created a safe harbor for parking arrangements. Under it, an Exchange Accommodation Titleholder (EAT) — typically a single-member LLC formed by your qualified intermediary — takes and holds legal title to one of the properties for you during the exchange. You and the EAT sign a written Qualified Exchange Accommodation Agreement memorializing the arrangement. When the timing is right, title transfers to you and the exchange completes.

The EAT is the linchpin: it lets you control and benefit from a property economically without holding title in your own name, which is what keeps the exchange valid. Because the structure involves forming an entity and operating a property through it, it is more involved than handing proceeds to an intermediary — which is the first hint of why reverse exchanges cost more.

Exchange-last vs. exchange-first

There are two ways to deploy the EAT, and the choice has practical consequences.

In an exchange-last structure, the EAT takes title to the replacement property you are buying and holds it until you sell your old property; then the replacement is transferred to you to complete the exchange. This is the more common approach, because it leaves the relinquished property in your hands while it is marketed and sold — you keep operating and selling the asset you know.

In an exchange-first structure, you take title to the replacement immediately, and the EAT instead parks the relinquished property until it sells. This is used less often, but can fit situations where, for example, financing on the new property is easier to obtain in your own name. Either way, the parked property must move out of the EAT within the deadlines.

The 45- and 180-day deadlines in reverse

The familiar windows apply, measured from the date the EAT parks a property. Within 45 days you must identify in writing the relinquished property you intend to sell, and within 180 days the parked property must be transferred out of the EAT and the exchange completed. As in any exchange, these are hard calendar-day deadlines with no weekend grace and only disaster-based relief — the same discipline we describe in our timeline memo. The compressed reality of a reverse exchange is that you are now juggling a purchase you have already made against a sale you must still complete inside 180 days, which raises the stakes on having your old property genuinely ready to sell.

Financing a reverse exchange

Financing is the practical hurdle that catches investors off guard. Because the EAT holds title to the parked property, any lender must be willing to make a loan to that arrangement — lending to the accommodation entity, often with the investor guaranteeing or providing the funds. Not every lender will do this, and those that will often want it structured carefully. For that reason, many reverse exchanges are completed with cash, or with portfolio and private lenders experienced in the structure. If your plan depends on conventional financing of the replacement, confirm lender willingness before you commit, not after.

Costs and complexity

A reverse exchange is materially more expensive than a standard delayed exchange. You are paying to form and operate the EAT, for additional legal documentation, and for the carrying costs of a parked property — and the qualified intermediary's fee for a reverse is a multiple of its delayed-exchange fee. We break the pricing down in our memo on 1031 costs. The added complexity is not a reason to avoid the structure; it is a reason to use it only when the value of securing the replacement property justifies the expense.

When a reverse exchange makes sense

A reverse exchange earns its cost in a specific set of circumstances: when you have found a replacement property you cannot risk losing, when the market is moving quickly and the seller won't wait for you to close your own sale, or when an off-market opportunity demands speed. It is the wrong tool when your old property isn't genuinely ready to sell, when you can't line up financing for the parking arrangement, or when a conventional delayed exchange — or a quick-closing DST as a backup — would serve just as well at lower cost. As always, the structure should follow the deal, not the other way around.

A worked example

Consider an illustrative case. You own a rental worth about $1,000,000 and have found a $1,200,000 replacement whose seller wants to close in 30 days — far too fast for you to sell your existing property first. You engage a qualified intermediary, who forms an EAT. Using an exchange-last structure, the EAT takes title to the $1,200,000 property (funded with your cash and a lender comfortable with the arrangement), parking it. You then list and sell your $1,000,000 property; within 45 days of parking you identify it as the relinquished property, and within 180 days you close that sale and the EAT transfers the replacement to you. The exchange completes, the gain defers, and you secured a property you would otherwise have lost. The cost — the EAT, the legal work, the financing gymnastics — was the price of timing, and in this scenario it was worth paying.

Combining a reverse with a build-to-suit

A reverse exchange can be combined with an improvement (build-to-suit) exchange, and the pairing is more common than investors expect. Here the EAT not only parks the replacement property but holds it while exchange funds are used to construct or renovate on it. The appeal is obvious: you can secure a property and then improve it to absorb your full proceeds, rather than being limited to whatever the property is worth as-is.

The constraint is the calendar. Any improvements meant to count toward your replacement value must be completed — and the improved property transferred to you — within the 180 days. Construction that runs past the deadline simply doesn't count toward the exchange, however far along it was. On any project with permitting, weather, or supply-chain exposure, that turns the 180-day window from a paperwork deadline into a genuine construction-management problem, and it is the single most common way improvement exchanges disappoint. Build only what you can realistically finish in the time, and budget contingency.

Risks specific to reverse exchanges

Buying first carries risks the standard exchange doesn't. The largest is the mirror image of its benefit: your old property still has to sell, inside 180 days. If it doesn't, the exchange can fail and you may be left owning the parked property — having already spent on the structure — or facing a costly unwind. The discipline that protects you is pricing the relinquished property to actually move, not to test the top of the market, and confirming demand before you commit to the purchase.

Two other risks compound it. Financing risk, because a lender must be willing to work with the parking arrangement, and a financing delay can run you into the deadline. And cost risk, because the higher fees and carrying costs of a reverse are sunk whether or not the exchange ultimately completes. A reverse exchange rewards investors who have genuinely lined up both ends of the trade and punishes those who treat the sale of the old property as an afterthought.

Frequently Asked Questions

How is a reverse exchange different from a normal 1031?

In a normal delayed exchange you sell first, then buy. In a reverse exchange you buy first, then sell, with an Exchange Accommodation Titleholder parking one property in the interim.

How long do I have to complete a reverse exchange?

The parked property generally must be transferred within 180 days, and the relinquished property identified within 45 days — the same windows as a standard exchange, measured from the parking date.

Can I finance a reverse exchange?

Yes, but the lender must be willing to lend while the Exchange Accommodation Titleholder holds title. Many reverse exchanges use cash or lenders experienced in the structure, so confirm financing before you commit.

Why does a reverse exchange cost more?

It requires forming and operating a holding entity (the EAT), extra legal documentation, and carrying the parked property — none of which a standard delayed exchange involves.

When should I use a reverse exchange?

When you've found a replacement you can't risk losing, the market is moving fast, or a seller won't wait for your sale to close. If a standard delayed exchange would work, it's usually cheaper.
