1031 Exchange Financing in Seattle: Timing the Loan

1031 exchange financing Seattle investors need has one rule above all others: the loan on the replacement property has to be underway before the property you are selling closes. Not after. The exchange itself runs on a 45 day identification clock and a 180 day closing clock that begin the day the relinquished property transfers, and neither one can be extended because your lender needed another week.

I get this call more often than any other investor call, and it usually comes about ten days too late. Someone has a duplex in Wallingford or a small building on Capitol Hill under contract, closing is a week out, and they are just now wondering whether they can roll the proceeds into something larger without writing the IRS a check.

They usually can. But the financing side of an exchange has moving parts that a straight purchase does not, and the parts that trip people up are almost always timing parts rather than qualifying parts.

This page covers what the lender is actually solving for in an exchange, the two clocks, the debt replacement requirement most investors have never heard of, what underwriting looks like, and one Washington specific catch that national articles about 1031 exchanges get wrong.

A note before we go further. I am a loan officer, not a CPA and not an attorney. Whether an exchange is right for you, whether your properties qualify, and how the tax math lands are questions for your tax advisor and your qualified intermediary. What follows is the lending side of the transaction only.

What 1031 Exchange Financing Seattle Investors Need Has to Solve

A like-kind exchange under Section 1031 of the Internal Revenue Code lets an investor defer federal capital gains tax by rolling the proceeds of one investment property into another, rather than taking the money. The IRS overview of like-kind exchanges is the plain summary, and since the 2017 tax law the treatment applies to real property only. Your primary residence does not qualify. A property you hold for investment or productive use in a trade or business generally does, subject to your CPA's read of your facts.

Here is the part that matters to me as your lender. In an exchange, you never touch the money. If the sale proceeds land in your account, even briefly, the exchange is generally blown and the gain becomes taxable in that year. The proceeds go from the closing table to a qualified intermediary, who holds them and later wires them into the purchase of the replacement property.

That single constraint reshapes the loan. On an ordinary purchase, your down payment sits in your account, gets documented, and gets wired. On an exchange, a large piece of the down payment is coming from a third party you do not control, on a date driven by a deadline rather than by your convenience, and the underwriter has to be able to see and verify all of it without it ever being in your name.

It works fine. It just has to be set up as an exchange from the first conversation rather than discovered halfway through.

The Two Clocks That Govern Everything

Both clocks start on the same day: the day the relinquished property closes and transfers. They run concurrently, not consecutively.

The 45 day identification period. Within 45 calendar days you must identify the replacement property or properties in writing, signed, and delivered to your qualified intermediary. Calendar days, including weekends and holidays. There are recognized identification rules your intermediary will walk you through, most commonly identifying up to three properties without regard to value. After day 45 the list is closed. You may buy something on the list. You may not add to it.

The 180 day exchange period. The purchase of the replacement property must close within 180 calendar days of the relinquished sale, or by the due date of your tax return for that year including extensions, whichever comes first. That second half of the sentence is the one that surprises people with a fourth quarter sale, and it is a question for your CPA before you list.

Neither deadline flexes. There is no lender extension, no good faith exception for an appraisal that came back late, and no relief because the seller of your replacement property asked for two more weeks. The IRS instructions for Form 8824, the form on which the exchange is reported, set out the reporting side.

Practically, that means the loan has to be built for a schedule that is shorter than it looks. If you identify on day 44 and the appraisal on a four unit building in a thin comparable market takes three weeks, you have burned a third of your remaining runway before underwriting has seen a valuation. This is exactly why I want the file open before the first property closes.

Why the Qualified Intermediary Has to Be in Place First

The qualified intermediary, often called a QI or an exchange facilitator, is not optional and cannot be hired retroactively. The agreement has to be signed and the intermediary has to be in position before the relinquished property closes, because the whole structure depends on the intermediary, not you, receiving the proceeds.

If your closing has already funded to you, an exchange is generally no longer available for that sale. I have had that conversation. It is short and unhappy.

What I need from the intermediary on the financing side is straightforward, and getting it early keeps the file clean:

• The exchange agreement, showing the intermediary holds the proceeds and naming the exchangor exactly as title will be taken.
• A statement of funds held, which is how the underwriter sources the down payment that is not in your account.
• Confirmation of who is wiring to escrow and when, so the closing agent and the lender are working from the same date.
• Whether the intermediary requires any particular vesting or assignment language, which affects how the loan is documented.

One structural point worth knowing: title on the replacement property generally has to be taken by the same taxpayer that sold the relinquished property. If the duplex was owned by an LLC and you were planning to buy the next building in your own name because it is easier to finance that way, stop and raise it with your CPA and your intermediary first. That is a tax structure question with real financing consequences, and getting it backwards is not fixable after closing.

The Debt Replacement Rule That Surprises Seattle Investors

This is the piece almost nobody arrives knowing, and it is the piece that decides how large the new loan has to be.

To defer the full gain, you generally have to do two things: reinvest all of the net proceeds, and acquire replacement property of equal or greater value. Value, not equity. If the relinquished property carried debt that was paid off at closing, that debt has to be replaced, either with new financing on the replacement property or with additional cash you bring in from outside the exchange.

Fall short on either count and the difference is generally treated as boot, which is taxable to the extent of gain. Reducing your debt in an exchange is not a neutral act. It can create a tax bill on money you never received.

Here is what that looks like in practice, using round numbers:

Illustrative example only, current as of August 2026, subject to change. Closing costs, depreciation recapture, partial exchanges, and your own basis all change the arithmetic. Your CPA and qualified intermediary determine the actual reinvestment and debt replacement targets for your exchange; I size the loan to the number they give me.

Notice what this does to the loan. In a normal purchase, an investor asks how little they can put down. In an exchange, the question inverts. You often have more cash than a lender would require, and the constraint becomes a minimum loan amount rather than a maximum. Sizing a loan down to what feels comfortable can cost you the deferral.

What Underwriting Looks Like on 1031 Exchange Financing Seattle Deals

The good news is that the loan itself is an ordinary investment property loan. There is no special 1031 product, no exchange rate, and no separate approval track. The exchange affects documentation and timing, not credit policy.

It is an investment property loan, with investment property terms. Down payment tiers, pricing, and reserve expectations follow the same rules I lay out in my guide to financing a rental property in Seattle. Occupancy is investment, and it will be underwritten that way.

Qualifying can go one of two ways. Agency financing looks at your personal income and your full schedule of real estate owned, including reserves for each financed property. If the personal income side is complicated, or the property carries itself well on its own rents, a DSCR loan qualified on the property's income is often the cleaner path in an exchange, particularly on a five unit or mixed use building where agency financing is not available at all.

Price often pushes past conforming. A trade up from a single Seattle rental into a larger building frequently lands above the 2026 King County conforming limit for a one unit property of $1,063,750, which puts the loan into jumbo or portfolio territory. My overview of Seattle jumbo mortgages covers why terms and timelines vary so much between lenders there, and timeline variance is not something an exchange tolerates well.

The down payment is sourced from the intermediary, not from you. Instead of two months of statements showing seasoned funds, the underwriter documents the exchange agreement and the intermediary's statement of funds held. Tell me it is an exchange at application and this is routine. Discover it at underwriting and it is a scramble.

The valuation is the schedule risk. Multifamily and mixed use appraisals in Seattle take longer than single family appraisals, and there are fewer appraisers who do them. Order it the day identification is final. If the number comes in under contract price, you are in the same position as any buyer, which I cover in what to do when the appraisal comes in low, except that you also have a 180 day wall behind you.

Lock deliberately. Exchange timelines are known but tight, and an extension fee is cheaper than a blown deferral. How lock periods, extensions, and float downs work is in my guide to rate locks in Seattle.

Washington's Excise Tax Does Not Go Away

This is the local point that national 1031 content consistently gets wrong, and it is worth knowing before you model your proceeds.

A 1031 exchange defers federal capital gains tax. It does not exempt the sale from Washington's real estate excise tax. Under WAC 458-61A-213, acquisition of property by an exchange facilitator in connection with a Section 1031 exchange is subject to real estate excise tax. The exemption in that rule covers only the facilitator's later transfer of the replacement property, and only where the tax was properly paid on the initial transaction and the supporting statement is attached. In other words, the tax is paid once on the sale, as it would be anyway. The exchange keeps it from being charged twice on the pass through leg. It does not make it disappear.

Washington's excise tax is graduated and paid by the seller. As published by the Washington Department of Revenue, the state portion currently steps from 1.10 percent on the portion of the price at or below $525,000, to 1.28 percent above that through $1,525,000, to 2.75 percent through $3,025,000, and 3.00 percent above that, with a local component added on top. Rates and thresholds current as of August 2026 and subject to change. Verify the current brackets and your local rate with the Department of Revenue before relying on them. On an appreciated Capitol Hill or Eastlake building, that is a meaningful number coming out of the proceeds the intermediary will be holding, which means it is a meaningful number coming out of what you have available to reinvest.

The counterpart worth knowing: Washington's capital gains excise tax exempts real estate, so the deferral you are pursuing in an exchange is federal, along with depreciation recapture. How that lands for you specifically is a CPA question, and the interaction of state and federal treatment is exactly the kind of thing worth paying for an hour of one's time to get right before you list.

Model the excise tax into your reinvestment target from the beginning. It is not a closing cost surprise so much as a proceeds surprise, and in an exchange, proceeds are the whole game. My breakdown of closing costs on both sides of a Seattle transaction covers what else comes off the seller side.

When 1031 Exchange Financing Seattle Deals Get Complicated

Two variations show up regularly here, and both are harder to finance than a standard forward exchange.

The reverse exchange. You find the replacement building before your current one sells, which in a market with thin small multifamily inventory happens often. In a reverse exchange, an exchange accommodation titleholder takes and parks title to one of the properties while the other sells, under a safe harbor the IRS established for this purpose. It works, but the parking arrangement means the entity on title is not you, and many lenders will not lend into that structure at all. The ones that will are usually portfolio lenders. Start these conversations very early, because lender selection, not qualification, is the binding constraint.

The improvement or build to suit exchange. Exchange funds are used to improve the replacement property, with the improvements counting toward the replacement value only if they are completed and in place before the 180 day deadline. That last clause is the whole difficulty. Construction in Seattle rarely respects a fixed calendar, and my guide to construction loans in Seattle covers how draw schedules actually run. Pairing that with an immovable federal deadline is possible and it is not for a first exchange.

A third case worth flagging: if part of your plan is pulling cash out of the replacement property shortly after closing, raise it with your CPA before the exchange, not after. Cash extracted around an exchange can be looked at as boot depending on timing and facts. My page on a cash-out refinance in Seattle covers the mechanics, but the sequencing question is a tax question.

How I Sequence 1031 Exchange Financing Seattle Timelines With Clients

The order matters more than any single step, so here is the sequence I actually run.

Before the listing. We talk. You tell me the estimated sale price and the payoff on the current property, and I tell you roughly what the replacement loan has to look like to satisfy debt replacement, and whether that loan is realistic on the kind of building you want next. Your CPA confirms an exchange makes sense at all. You engage a qualified intermediary.

While the relinquished property is under contract. The loan file opens. Income, assets, and your schedule of real estate owned go in, even though there is no subject property yet. This is the single highest leverage thing an exchange buyer can do, and it is the step people skip. My guide to mortgage pre-approval in Seattle covers what that document set looks like.

Days 1 through 45. You shop, I underwrite the buildings you are seriously considering as you find them, so identification is an informed list rather than three hopeful addresses. Identification goes to the intermediary in writing.

Day 45 forward. Appraisal ordered immediately. Title and escrow coordinated with the intermediary so everyone is working to the same wire date. Lock set with the deadline, not the closing date, as the outer boundary.

Closing. Intermediary funds, loan funds, and the exchange is reported on your return by your CPA.

Run in that order, an exchange is a well organized purchase with an unusual down payment source. Run backwards, it is a fire drill with a tax bill at the end. If you are earlier in your investing than this and just building the portfolio, my pages on house hacking in the U District and ADU financing in Seattle cover the ground floor of the same path.
