Reverse 1031 Exchange: How to Buy the Replacement Property Before You Sell

Why a reverse exchange exists

A standard deferred exchange requires you to sell first, place the proceeds with a qualified intermediary, and buy within 180 days. The sequence fails when the right replacement property is available now and your sale is months away, when a seller will not wait, or when a 1031 buyer wants to lock in a NNN property before its lease term shortens. The tax code does not allow you to own both properties at once and call it an exchange, so the solution is for someone else to own one of them temporarily.

Revenue Procedure 2000-37 created a safe harbor for that arrangement. If the parking follows its rules, the IRS will not challenge the exchange on the ground that you owned the replacement property before selling the relinquished property. Reverse exchanges outside the safe harbor are possible but rest on case law and are riskier; most exchanges in practice stay inside it.

How the safe harbor works, step by step

The parties are you (the exchanger), your qualified intermediary, and an exchange accommodation titleholder, usually a single-purpose LLC owned by the intermediary or an affiliated accommodator. The sequence for the common exchange-last structure:

1. Before closing on the replacement property, engage the intermediary and accommodator and sign the qualified exchange accommodation agreement (QEAA). The agreement must be in place no later than five business days after the EAT takes title; in practice it is signed at or before closing.
2. The EAT acquires the replacement property. You fund the purchase, either by lending the money to the EAT or by arranging a third-party loan to the EAT that you guarantee. The EAT typically leases the property back to you on a triple net basis so you operate it, carry insurance naming the EAT, and pay the expenses.
3. Within 45 days of the EAT taking title, identify in writing the property you will sell, under the same identification rules as a forward exchange.
4. Sell the relinquished property. The buyer's contract should acknowledge your exchange and your right to assign to the intermediary. Proceeds go to the intermediary, never to you.
5. The intermediary uses the proceeds to acquire the replacement property from the EAT and conveys it to you, often by assigning the membership interest in the EAT's LLC rather than by deed. The loan you made to the EAT is repaid from the proceeds, or the third-party loan is assumed.
6. All of this closes within 180 days of the EAT taking title, and both legs are reported on the same year's return, which can require an extension.

Exchange-first: parking the property you are selling instead

If your lender will not lend to an accommodator, the alternative is to park the relinquished property. The EAT takes title to the property you are selling, you treat that transfer as the first leg of the exchange, and you buy the replacement property directly in your own name with the intermediary's involvement. The EAT then sells the relinquished property to the ultimate buyer within 180 days, and the proceeds settle the exchange.

Exchange-first lets you use conventional financing on the purchase, since you are the borrower and owner. The trade-off is that the relinquished property's value must be fixed at the time of parking, usually by appraisal, and any later sale price above that value can be taxable. It also moves an existing loan on the relinquished property, which the lender must consent to. Choose the structure with the intermediary, the lender, and your CPA before anything is signed.

Improvement and build-to-suit exchanges use the same tool

The same safe harbor supports an improvement exchange, where the EAT holds the replacement property while construction or renovation is completed with exchange funds, so that the improved value counts as replacement property. The 180-day limit applies to the parking, which means a build-to-suit must be far enough along that the improvements are real property by the deadline; money set aside for unfinished work does not count and is taxable boot. Improvement exchanges are common for owner-users building a facility and for investors adding value to a NNN pad before taking title.

Financing, costs, and risk

A reverse exchange requires the purchase to be funded before the sale closes. The sources are your own cash, a loan to the EAT secured by the parked property and guaranteed by you, or a lender willing to make a loan to the accommodator. Not every lender will; ask early. Expect the accommodator's fee, intermediary fee, additional title, legal, and entity costs, and a second set of closing costs on the parked property, so a reverse exchange typically costs several times a forward exchange. The deferred tax usually dwarfs those costs, which is the point, but the math should be run first.

Risk sits in two places. The relinquished property must sell within 180 days; if it does not, the EAT conveys the parked property to you and the exchange fails, leaving you with two properties and no deferral. And during the parking period the EAT is the owner of record, so environmental, liability, and insurance matters are handled through indemnities and the lease. An experienced accommodator has forms for all of it; a first-time one does not.

New Mexico specifics

New Mexico has no real estate transfer tax or documentary stamp tax, so the extra conveyance through the accommodator costs nothing in transfer tax. In states with a deed or documentary transfer tax, such as Colorado's documentary fee, Nevada's real property transfer tax, or California's county transfer taxes, a reverse exchange can be taxed on both conveyances; here it is not. New Mexico county recording fees are flat per document rather than scaled to price.

Two other points. Accommodator and intermediary fees are services and carry New Mexico gross receipts tax. And a transfer to the EAT can trigger a property tax reassessment conversation with the county assessor; New Mexico assesses on one-third of value, and a sale is a reassessment event, so understand what the parking does to the tax bill before choosing which property to park. A completed exchange defers New Mexico's income tax on the gain along with the federal tax.

When a reverse exchange is the right call

A reverse exchange makes sense when all of the following are true.

• The replacement property is available now and worth more to you than the cost and complexity of parking.
• You can fund the purchase before the sale, from cash, a loan to the accommodator you guarantee, or a lender that will work with the structure.
• The relinquished property will realistically sell within 180 days at a price that supports the exchange; a stale listing is a warning sign.
• Your intermediary and accommodator have done reverse exchanges in New Mexico before and can produce the QEAA, lease, and indemnity forms immediately.
• Your CPA has modeled the deferral against the added costs and confirmed the structure, exchange-last or exchange-first, before any contract is signed.
