1031 Exchange Financing: Lining Up Debt Before the 45-Day Deadline

The two deadlines, counted precisely

Both periods begin on the same event: the date the relinquished property is transferred, which for most sales is the closing date. Day one is the day after.

• The identification period ends at midnight on the 45th day. By then you must have identified replacement property in a written document, signed by you, delivered to the qualified intermediary or another party to the exchange who is not a disqualified person. Telling your own broker or attorney does not count.
• The exchange period ends at the earlier of two dates: midnight on the 180th day after the transfer, or the due date, including extensions, of your income tax return for the tax year in which the transfer occurred. The replacement property must actually be received by then.

Two features catch people out. The 180 days are not additional to the 45 — they run concurrently from the same start date, so a full 45-day identification leaves 135 days to close. And the second limb is real: sell late in the calendar year and your 180th day falls after the standard filing deadline, so without an extension the exchange period ends on that deadline instead.

The periods do not extend for weekends or holidays, and no discretionary extension exists. The only relief comes from IRS disaster-relief notices in federally declared disaster areas.

What you can identify, and how

Identification must be unambiguous — a legal description, a street address, or a distinguishable property name. For property to be constructed, describe the land and the improvements as specifically as is practicable. You may revoke an identification and substitute another, but only in writing, delivered the same way, inside the 45 days. How many properties you can name is governed by three alternative rules, and you need to satisfy one:

The three-property rule is why lenders get asked to look at more than one deal at once. Backups are not decoration: if your primary target dies in diligence on day 60, the only properties you can buy are those named by day 45.

Debt replacement and boot

Full deferral requires two things at once: reinvest all the net proceeds, and do not reduce your debt. The replacement should cost at least the net sale price of the relinquished property, all net equity held by the intermediary must go into it, and the debt you take on must at least equal the debt paid off.

Boot is anything you receive that is not like-kind property. It takes two forms:

• Cash boot — exchange proceeds that come back to you rather than into the replacement property, including proceeds spent on non-transaction costs.
• Mortgage boot — net debt relief. If you retired more debt on the sale than you took on at the purchase, the difference is boot even though no cash reached you.

Gain is recognized to the extent of boot received, capped at total realized gain. The rule that decides most financing questions is the asymmetry between the two forms: you can offset mortgage boot by contributing additional cash to the purchase, but you cannot offset cash boot by taking on additional debt. Borrowing more than the debt you retired does not shelter cash you pulled out of the closing.

An illustration only: a relinquished property sells for net price S with a mortgage payoff of D, leaving net equity E. If the replacement costs S and the new loan is exactly D, E goes in and no boot arises. If the new loan comes in below D, the shortfall is mortgage boot, and you can eliminate it by wiring that shortfall from your own funds. If instead you borrow more and have the intermediary release E to you, that cash is boot regardless of loan size. Loan sizing therefore matters more here than in an ordinary purchase: a loan that comes in short is a taxable event, not just a funding gap.

Vesting: the same taxpayer rule

The taxpayer that sold the relinquished property must be the taxpayer that acquires the replacement property. Lenders on larger commercial loans often want a newly formed single-purpose entity as borrower, which appears to conflict with that requirement.

The usual resolution is a single-member limited liability company owned entirely by the exchanging taxpayer, which is generally disregarded for federal income tax purposes and therefore treated as the same taxpayer. Raise it with the lender and the intermediary early and confirm it with your own tax counsel — retitling after closing does not fix a vesting problem, and documents drawn in the wrong name take time to redraw.

A working timeline for the loan

1. Before the relinquished closing: engage the qualified intermediary, who must be in place before that sale closes, and open lender conversations while nothing is running.
2. Days 1 to 15: circulate the strongest candidates for indicative terms and assemble the borrower package — personal financial statement, schedule of real estate owned, entity documents, two to three years of returns.
3. Days 15 to 40: get the primary target under contract and request a term sheet, confirming loan sizing against the debt being retired, not just the purchase price.
4. Day 45: deliver the signed identification to the intermediary. Name backups.
5. Days 45 to 60: sign the term sheet and pay third-party deposits so the appraisal, environmental and property condition reports are ordered immediately.
6. Days 60 to 120: reports delivered, title and survey reviewed, credit approval issued.
7. Days 120 to 165: documents drawn, vesting confirmed, insurance and estoppels collected, closing conditions cleared.
8. Days 165 to 180: fund and record. The 180th day is a hard stop, so build in slack.

The pressure point is visible in that sequence. An appraisal is ordered after the term sheet is signed, and a term sheet is rarely signed before day 45, so anything that delays it consumes the appraisal’s slack.

When the timeline will not stretch

Short-term debt exists precisely for this. If permanent financing cannot be underwritten inside the window, bridge loans can close the acquisition on time and be refinanced afterward, once the pressure is off. The requirement is that you acquire the replacement property inside 180 days; nothing requires the loan you close with to be the loan you keep. The bridge loans california sponsors use for this are underwritten primarily on the asset, which is why they move faster.

Two variants are worth knowing. A reverse exchange, where you buy first and sell afterward, parks the property with an exchange accommodation titleholder under the safe harbor in Revenue Procedure 2000-37; the 45-day and 180-day clocks still run from the parking date, and lenders willing to lend to a titleholder entity are a narrower group. An improvement exchange lets exchange funds pay for construction, but only work completed inside the 180 days counts toward the value.

What this means for your deal

The decision that determines whether 1031 exchange financing works is made before day 45. Size the new loan against the debt you are retiring and confirm that number with a lender in writing before you identify. If proceeds fall short you have two choices — bring cash to cover the gap, or accept mortgage boot and the tax that follows — and both are easier to arrange on day 30 than on day 170.

Identify backups seriously, with a lender who has already looked at each one, because diligence kills replacement properties and a backup nobody has priced is not a backup. Mission Valley Capital arranges 1031 exchange financing through local banks, national banks, correspondent lenders, alternative lenders and private-money sources, which matters when the timetable is fixed: the transaction can be placed with the channel whose process fits the days remaining, with closings as fast as 5–10 days depending on the transaction. The tax positions stay with your qualified intermediary and tax advisor, and the financing is built around what they confirm.
