The quick read: You finance a 1031 replacement property before the relinquished sale closes by running a reverse exchange. Under IRS Revenue Procedure 2000-37, an exchange accommodation titleholder takes title to the replacement, a short-term bridge loan is made to that titleholder's entity with your guaranty, and the sale must close within 180 days. The federal windows are fixed: the IRS Form 8824 instructions say replacement property must be identified within 45 days after you transfer the property you give up and received within 180 days, or by your return's due date if earlier. What changes is the loan file, because the borrower of record, the title holder and the source of the down payment all move.
Why can't you just buy the replacement property first with a bridge loan?
You cannot simply buy the replacement in your own name with a bridge loan and sell the old property later, because the deferred-exchange rules assume the relinquished property goes first, and the IRS reverse-exchange safe harbor excludes replacement property you already owned within 180 days before it was parked.
The order matters because of how the statute is built. Revenue Procedure 2000-37 recites section 1031(a)(3): property you receive is not treated as like-kind property if it is not identified within 45 days after you transfer the relinquished property, or if it is received after the earlier of 180 days or your return's due date, with extensions. The same document notes that the preamble to the 1991 deferred-exchange regulations says those rules do not apply to "reverse-Starker" exchanges, where the replacement is acquired before the relinquished property is transferred.
Revenue Procedure 2004-51 then closed the obvious workaround. It added a limitation that the safe harbor does not apply to replacement property held in a qualified exchange accommodation arrangement if the taxpayer owned it within the 180-day period ending on the date it was transferred to the accommodation titleholder. So a bridge loan that closes in your LLC's name, on a building you intend to use as the replacement, can take the property outside the safe harbor before the exchange has started.
Identification deadline (IRS Form 8824 instructions, 2025): within 45 days after you transfer the property you give up Receipt deadline (IRS Form 8824 instructions, 2025): within 180 days, or by the due date of your tax return including extensions, whichever is earlier Prior-ownership bar (Rev. Proc. 2004-51): replacement property owned by the taxpayer within the 180-day period before parking is outside the safe harbor
How does a reverse exchange let you close on the replacement first?
A reverse exchange lets you close on the replacement first by having an exchange accommodation titleholder, a party that is neither you nor a disqualified person, hold title while you sell the old property, with the paperwork and both sales completed inside the 180-day safe harbor in Revenue Procedure 2000-37.
The revenue procedure calls the holding structure a qualified exchange accommodation arrangement, and section 4.02 lists the conditions. The titleholder must hold qualified indicia of ownership, which the document defines to include legal title or interests in a disregarded entity, such as a single member limited liability company, that holds title. You and the titleholder must sign a written qualified exchange accommodation agreement no later than five business days after the titleholder takes title. The relinquished property must be identified no later than 45 days after the replacement is parked. No later than 180 days after the transfer, the parked property must move to you as replacement property, or to an unrelated buyer as relinquished property, and the combined time both properties sit in the arrangement cannot exceed 180 days.
Agreement deadline (Rev. Proc. 2000-37, sec. 4.02(3)): no later than five business days after title moves to the titleholder Relinquished identification (Rev. Proc. 2000-37, sec. 4.02(4)): no later than 45 days after the replacement is parked Hand-off deadline (Rev. Proc. 2000-37, sec. 4.02(5) and (6)): no later than 180 days, with combined parking time capped at 180 days
There are two common shapes. In the version the procedure describes first, the titleholder parks the replacement until you arrange the sale of your existing property. In the other, which section 2.05 also describes, the accommodation party acquires the replacement, immediately exchanges it with you for the relinquished property, and then holds the relinquished property until the sale closes. The first keeps the new building off your balance sheet during the window; the second puts you on title at once but leaves the titleholder holding the old one. Your qualified intermediary and tax adviser choose the shape; the lender has to underwrite whichever one they pick.
Who borrows the bridge loan in a reverse exchange, and what changes in the loan file?
In a parked-replacement reverse exchange the bridge loan is typically made to the titleholder's single-purpose entity, because that entity holds title, and Revenue Procedure 2000-37 expressly lets you guarantee the titleholder's acquisition debt, advance it funds, lease the property and manage it without breaking the safe harbor.
Section 4.03 is the part a lender's counsel reads closely. It says property will not fail to be treated as held in the arrangement if the taxpayer guarantees some or all of the titleholder's obligations, including secured or unsecured debt incurred to acquire the property; loans or advances funds to the titleholder; leases the property from the titleholder; manages it, supervises improvements or acts as contractor; or enters puts and calls at fixed or formula prices for up to 185 days from acquisition. Those permissions are what make a bridge loan workable: the entity is the borrower, you are the guarantor and the economic sponsor, and a master lease or management agreement keeps the rents flowing to you.
That changes the bridge file in five places:
- Borrower of record. The loan closes to the titleholder's entity, so the lender needs its formation documents and the qualified exchange accommodation agreement, not just yours.
- Guaranty. Your personal or entity guaranty carries the credit, so lender review of your financial statement and liquidity looks like a recourse loan.
- Equity source. Your down payment usually arrives as a loan or advance to the titleholder, which the lender will want documented and subordinated.
- Term. The safe harbor ends at 180 days, so the loan's maturity, extension options and exit must line up with that calendar rather than a generic 12-month bridge.
- Assignment. When the property moves to you, the loan is assumed, refinanced or paid down, and the lender has to consent to whichever path the exchange documents use.
A bridge lender is also lending without the sale proceeds you are about to receive. The deferred-exchange regulations at 26 CFR 1.1031(k)-1(g)(6) require the exchange agreement to say you have no right to receive, pledge, borrow or otherwise obtain the benefits of the money before the exchange period ends, except in narrow circumstances. A lender cannot take an assignment of the intermediary account as collateral the way it would take a deposit, so the bridge has to be sized on the replacement property and your guaranty alone. A bridge loan sized that way usually leaves you funding more equity up front than you will need after the sale.
How do the three bridging structures compare?
The three structures differ mainly on who is on title during the window, who borrows, and what retires the bridge, so compare them on those lines before you pick one; the federal 45-day and 180-day limits apply in every case, and none of the three removes them.
| Attribute | Parked replacement (exchange last) | Parked relinquished (exchange first) | Refinance into permanent exit |
|---|---|---|---|
| Attribute Who holds the new building during the window | Parked replacement (exchange last) Accommodation titleholder's entity | Parked relinquished (exchange first) You, from the first closing | Refinance into permanent exit You, after the hand-off |
| Attribute Bridge borrower of record | Parked replacement (exchange last) Titleholder's entity, with your guaranty | Parked relinquished (exchange first) You, on the replacement | Refinance into permanent exit You, on the replacement |
| Attribute What the titleholder holds | Parked replacement (exchange last) The replacement | Parked relinquished (exchange first) The relinquished property | Refinance into permanent exit Nothing once the exchange ends |
| Attribute Equity source at the first closing | Parked replacement (exchange last) Your loan or advance to the titleholder | Parked relinquished (exchange first) Your cash, plus funding the titleholder's purchase of the old building | Refinance into permanent exit Not applicable; it retires the bridge |
| Attribute Clock that governs the loan term | Parked replacement (exchange last) 180-day safe harbor in Rev. Proc. 2000-37 | Parked relinquished (exchange first) 180-day safe harbor in Rev. Proc. 2000-37 | Refinance into permanent exit Lender's own stabilization and rate test |
| Attribute What retires the bridge | Parked replacement (exchange last) Exchange proceeds at hand-off, then a permanent loan | Parked relinquished (exchange first) Sale of the relinquished property, then a permanent loan | Refinance into permanent exit The permanent loan itself |

How does the refinance into a permanent loan finish the exchange?
The refinance into a permanent loan finishes the financing side of the exchange once title has moved to you, because a 180-day bridge is a placeholder; the permanent lender sizes on the property's coverage and value, and the exchange proceeds that arrive at the hand-off reduce how much permanent debt you need.
Plan the bridge loan exit before the first closing. The permanent lender will want the property in your name or your borrowing entity's, a clean title history showing the titleholder's ownership and the transfer to you, the exchange closing statement showing where the intermediary's funds went, and a rent roll or leases that support the debt service coverage test. A permanent loan can take longer to close than the hand-off itself, so many sponsors negotiate a bridge with extension options that reach past the 180th day even though the exchange cannot.
Debt matters to the tax result as well as to the lender. The Form 8824 instructions direct filers to Regulations section 1.1031(d)-2 and work an example: Taylor gives up a building with an $80,000 mortgage, receives a building with a $150,000 mortgage plus $40,000 in cash, and reports only the $40,000 cash on line 15, because the $80,000 of liabilities the other party assumed does not exceed the $150,000 Taylor assumed. In the same example, Taylor's basis line adds the $70,000 excess of liabilities assumed over liabilities relieved. The practical reading for a borrower is that the replacement's debt and the old property's payoff interact on the return, so the size of the permanent loan is a tax question too. Run that with your adviser before you set the loan amount.
What does an illustrative reverse exchange look like on paper?
On an illustrative $3,000,000 replacement bought before a $2,000,000 relinquished sale, a 70% bridge to the titleholder's entity leaves $900,000 of equity to advance, and the old property's $800,000 payoff and roughly $1,200,000 of net proceeds then reshape the permanent loan at the hand-off.
Every figure below is an assumption chosen for illustration, not a quote, a rate or a tax projection, and closing costs and intermediary fees are left out to keep the arithmetic visible.
Replacement purchase price: $3,000,000 (assumption) Bridge loan to titleholder's entity at 70% of price: $2,100,000 (our arithmetic) Your loan or advance to the titleholder: $900,000 (our arithmetic) Relinquished sale price: $2,000,000 (assumption) Existing mortgage paid off at that sale: $800,000 (assumption) Net sale proceeds held by the qualified intermediary: $1,200,000 (our arithmetic, before costs)
On those numbers the debt relieved on the old building, $800,000, is well below the $2,100,000 of debt on the new one, which is the direction the Form 8824 example treats as not producing liability boot. How the $1,200,000 of exchange funds is applied at the hand-off, whether to buy the property from the titleholder, to repay your advance or to pay down the bridge, is set by the exchange documents and your tax adviser, not by the lender. What the lender sees is the outcome: a property in your name with a bridge balance that the permanent loan has to retire on its own coverage.
How do you get lenders to quote a reverse-exchange bridge?
You get lenders to quote a reverse-exchange bridge by sending a package that names the exchange structure, the titleholder, the 180-day calendar and the permanent exit up front, so each lender is pricing the same borrower-of-record and guaranty arrangement rather than a generic purchase loan.
YieldStack is a commercial mortgage brokerage. Its software matches the deal against a catalog of 20,000+ loan programs, which is a count of programs, and human brokers structure the request, negotiate for the borrower and carry the deal toward closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
What to send:
- The replacement property's contract, rent roll and operating statement
- The relinquished property's contract or listing status, and its payoff statement
- The intermediary or titleholder's name and a draft of the accommodation agreement
- Your target closing date for each property and the 45-day and 180-day dates that follow
- Your guarantor financial statement and liquidity
- The permanent loan you expect to refinance into, with a target amount
A bridge loan calculator gives you a first pass at carry over the window. When the file is ready, send the deal for review. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing.
The bottom line
Financing a 1031 replacement before the old property sells is a reverse exchange, not a race. Park one of the properties with an exchange accommodation titleholder, sign the agreement within five business days, lend the bridge to the titleholder's entity on your guaranty, keep everything inside 180 days, and line up the permanent loan that retires the bridge before you sign the first contract.
