Why parking arrangements exist
In a standard 1031 exchange, you sell first and buy second within 180 days. A reverse exchange flips the order: you buy the replacement before you have sold the relinquished property. The problem is that for a valid 1031 exchange, you cannot own both properties simultaneously — the IRS will treat it as a purchase with no exchange. The solution is a parking arrangement: an independent third party, the Exchange Accommodation Titleholder (EAT), legally holds title to one of the properties on your behalf while you complete the transaction.
The EAT is typically an LLC that your qualified intermediary (QI) or a related firm creates specifically for the transaction. You enter into a Qualified Exchange Accommodation Agreement (QEAA) with the EAT, which governs the terms of the arrangement.
IRS Revenue Procedure 2000-37 safe harbor
The IRS provided a safe harbor for parking arrangements in Revenue Procedure 2000-37 (updated by Rev. Proc. 2004-51). To qualify: the QEAA must be signed within five business days of the EAT taking title; the EAT must relinquish the property within 180 days; and the taxpayer must identify the relinquished property within 45 days of the EAT acquiring the replacement. The EAT cannot be the taxpayer, a disqualified person, or the QI — it must be a true third party.
Inside the safe harbor, the IRS agrees not to challenge the arrangement as a sham. Outside it — for example, if you need more than 180 days — there is no guarantee, though some practitioners have argued successfully under general exchange principles.
Costs and practical considerations
Parking arrangements add complexity and cost. The EAT charges a fee for holding title, there are additional legal documents (QEAA, operating agreement, deed transfers), and lenders are often unfamiliar with the structure (getting a loan in the EAT's name requires a cooperative lender). Reverse exchanges also require more planning lead time than forward exchanges. Despite the friction, parking arrangements are an important tool when a compelling replacement property appears before you are ready to sell the relinquished one.
Exchange-first versus exchange-last parking
A parking arrangement can be built two ways, and the choice affects your financing and risk. In an exchange-last (also called 'exchange-first') structure, the EAT parks the replacement property: the EAT takes title to the new property you want, holds it, and later transfers it to you once your old property sells. In an exchange-first variation, the EAT instead parks the relinquished property — you take title to the replacement right away, and the EAT holds your old property until a buyer is found.
Most reverse exchanges park the replacement, because it is usually easier to place financing and because you keep operating your existing property normally while you hunt for a buyer. Parking the relinquished property is used when a lender will not lend to the EAT on the new purchase but will lend to you directly. Your qualified intermediary and attorney choose the structure based on which property is easier to finance and which title transfer is cleaner.
The 45-day and 180-day clocks in a reverse exchange
Reverse exchanges use the same deadlines as forward exchanges, applied from the EAT's acquisition. Within 45 days of the EAT taking title to the parked property, you must formally identify the property that will be relinquished (or, in a replacement-parking deal, the replacement being acquired), following the usual identification rules — the three-property rule, the 200% rule, or the 95% rule. The entire arrangement must close, with the EAT transferring the parked property out, within 180 days.
These deadlines are firm and do not extend for weekends, holidays, or a slow sale market. That is the practical squeeze of a reverse exchange: you have committed to buying the replacement, but you now have only 180 days to sell the old property, or the safe harbor collapses and the transaction is treated as a taxable purchase. Pricing the relinquished property to actually move within the window is essential — an overpriced listing is the most common way a reverse exchange fails.
Financing the parked property
Because the EAT holds legal title, any loan on the parked property is typically made to the EAT, which most conventional lenders will not do. In practice the taxpayer usually lends the funds to the EAT or personally guarantees a third-party loan, and the loan documents and QEAA spell out that the taxpayer bears the economic burden. Rev. Proc. 2000-37 explicitly permits the taxpayer to advance funds to, or guarantee the debt of, the EAT without breaking the safe harbor.
This is why reverse exchanges are more capital-intensive: you often need the cash or credit to acquire the replacement before your old property's equity is freed up by its sale. Investors who cannot bridge that gap sometimes use short-term bridge financing or lines of credit. Line up the funding source before you engage an EAT, because the clock starts the moment the EAT takes title.
Costs, taxes, and hidden frictions
Parking arrangements carry real costs beyond the EAT's holding fee: legal drafting of the QEAA and the special-purpose LLC, potential transfer taxes or reassessment triggers on the extra deed transfers (some states and counties tax each conveyance, which can be significant), lender fees for an unfamiliar structure, and additional title insurance. In some jurisdictions the double transfer to and from the EAT can even trigger a property-tax reassessment, so check state and local rules before committing.
There is also an operational wrinkle: while the EAT holds title, it is technically the owner of record, so leases, insurance, and liability need to be arranged so the taxpayer retains the economic benefits and burdens without breaching the safe harbor. A well-drafted QEAA assigns the net lease of the parked property to the taxpayer so rents and expenses flow correctly. These frictions are why reverse exchanges cost more and take more lead time than a standard forward exchange.
When a reverse exchange is worth the trouble
Despite the cost, a parking arrangement is the right tool in a few clear situations: a rare or ideal replacement property comes to market before you are ready to sell and you cannot risk losing it; a hot seller's market makes you confident the relinquished property will sell fast but you must lock the replacement now; or a construction/improvement exchange, where the EAT holds title while improvements are built on the replacement before it transfers to you (an 'improvement' or 'build-to-suit' exchange, often layered on top of a parking structure).
Weigh the added fees and the 180-day pressure against the cost of missing the replacement or triggering a fully taxable sale. When the deferred tax is large and the replacement is genuinely irreplaceable, the several thousand dollars of extra structuring cost is minor insurance. When the replacement is fungible, a standard forward exchange is almost always simpler and cheaper.
Independence and the disqualified-person rules
The safe harbor works only if the EAT is genuinely independent. The EAT cannot be the taxpayer, a related party, or a disqualified person — and the disqualification rules reach further than most investors expect. Anyone who has acted as your employee, attorney, accountant, investment banker, or real estate agent within the two years before the transaction is generally disqualified from serving as your intermediary or accommodator. That is why the EAT is almost always a fresh, special-purpose LLC formed by a professional exchange company that has no other relationship with you.
This independence requirement also shapes who runs the deal: a single professional exchange company typically provides both the qualified intermediary (for the forward leg of the exchange) and the EAT (for the parking leg), because both must be arm's-length from you. Do not try to economize by using your own attorney's LLC or a friendly entity as the accommodator — a defective EAT can blow the safe harbor and turn the whole arrangement into a taxable purchase. Vet the exchange company's experience with reverse and improvement exchanges specifically, since they are more complex than ordinary forward exchanges.
Frequently asked questions
What is an Exchange Accommodation Titleholder (EAT)?
An EAT is a neutral third-party entity (usually an LLC) that holds legal title to either the replacement or relinquished property during a reverse 1031 exchange, allowing the investor to avoid owning both properties simultaneously.
Can I lend money to the EAT to buy the replacement?
Yes. Rev. Proc. 2000-37 specifically allows the taxpayer to advance funds to, or guarantee the debt of, the EAT without breaking the safe harbor. This is common because most banks will not lend directly to the EAT.
Do the 45-day and 180-day deadlines apply to reverse exchanges?
Yes. You must identify the relinquished (or replacement) property within 45 days of the EAT taking title, and the whole arrangement must close within 180 days. The clocks are firm and do not extend for a slow sale.
Can a parking arrangement trigger extra transfer taxes?
It can. The property passes through two deed transfers (to and from the EAT), and some states and counties tax each conveyance or reassess property value. Check local transfer-tax and reassessment rules before structuring a reverse exchange.
How long can the EAT hold the property?
Under the IRS safe harbor (Rev. Proc. 2000-37), the EAT must release the property within 180 days of acquiring it.
Is a parking arrangement the same as a reverse exchange?
Yes — a reverse exchange uses a parking arrangement as its mechanism. The terms are often used interchangeably.
Can my own attorney or company serve as the EAT?
Generally no. The EAT must be independent and cannot be a disqualified person — which includes anyone who has been your attorney, accountant, or agent within the prior two years. The EAT is almost always a special-purpose LLC formed by an arm's-length professional exchange company.
