The short answer

A vacation rental qualifies for a 1031 exchange when it is held for investment. The IRS safe harbor in Rev. Proc. 2008-16 says a dwelling unit qualifies if you owned it at least 24 months before the exchange and, in each of the two 12-month periods, rented it at fair rental for 14 or more days and kept personal use to no more than the greater of 14 days or 10% of rental days. Mirror rules apply to the replacement property for 24 months after.

You have 45 days from closing to identify replacement property in writing to a qualified intermediary and 180 days to close. The intermediary must hold the proceeds; if you touch the money, the exchange fails.

Common exits for Seattle and Eastside owners: a long-term rental closer to home, a multifamily building, a net-leased commercial property, or a Delaware statutory trust interest for a fully passive position. All three depreciation buckets on the capital gains page defer with the gain.

For an owner who took large depreciation deductions on a short-term rental, the 1031 exchange is often the difference between a sale that makes sense and one that does not. It defers the capital gain, the 25% recapture on the building and the ordinary-income recapture on cost-segregated property into the replacement asset. Owners use it to move out of a market whose permit rules have turned against them and into an asset that fits the next decade: a Renton or Kent long-term rental that the 2025 rent-stabilization law still allows to be operated profitably, a small apartment building, a net-leased retail pad, or a statutory-trust interest that arrives with no tenants to manage.

The rules are mechanical and unforgiving on timing, and a short-term rental adds two questions a plain rental does not raise: whether personal use disqualified the property, and whether the furnishings are part of the exchange. RexMont is not a tax adviser or a qualified intermediary; we coordinate the sale, the identification and the replacement purchase with both, and we start that coordination before the property is listed, because the 45-day clock does not.

Does a vacation rental qualify? The Rev. Proc. 2008-16 safe harbor

Section 1031 applies to real property held for productive use in a trade or business or for investment. A cabin you mostly use yourself is not held for investment, and the IRS has litigated that point. Rev. Proc. 2008-16 gives a safe harbor: the IRS will not challenge whether a dwelling unit qualifies if, for the relinquished property, you owned it for at least 24 months immediately before the exchange and in each of the two 12-month periods within that window you (1) rented it at a fair rental for 14 days or more and (2) did not use it personally for more than the greater of 14 days or 10% of the days it was rented at fair rental. The same two tests apply to the replacement dwelling for the 24 months after the exchange.

Personal use includes use by family members and by anyone paying less than fair rent; days you spend at the property doing repairs and maintenance full time generally do not count. Most self-managed Washington short-term rentals clear the 14-day rental test easily; the trap is the personal-use ceiling for owners who blocked the summer or the ski weeks for themselves. A property outside the safe harbor can still qualify on the facts, but you lose the certainty.

The clocks and the intermediary

  1. 1Before listing: engage a qualified intermediary (QI) and have the exchange agreement and assignment language ready for the purchase and sale agreement. Your CPA runs the gain and the boot analysis.
  2. 2At closing of the relinquished property (day 0): proceeds go to the QI, never to you. Under Treas. Reg. §1.1031(k)-1 the identification period ends at midnight on the 45th day and the exchange period at midnight on the 180th day (or your tax return due date including extensions, if earlier).
  3. 3By day 45: identify replacement property in a signed writing delivered to the QI. Up to three properties of any value, or any number whose combined value does not exceed 200% of what you sold, or, if you exceed both, you must acquire 95% of what you identified.
  4. 4By day 180: close on the replacement property or properties. To defer all gain, buy real property of equal or greater value, reinvest all net equity, and replace the debt you paid off (or add cash). Cash or debt relief you keep is "boot" and is taxed.
  5. 5After closing: hold the replacement property for investment; if it is a dwelling unit, observe the 24-month safe harbor tests on the replacement side.

The dates do not move

Weekends, holidays, a slow lender and a failed inspection do not extend 45 or 180 days. RexMont builds the replacement search before the relinquished property closes, so day 45 arrives with a signed identification, not a scramble.

Short-term rental specifics

  • Furnishings are personal property and are not like-kind to real property. Sell them by separate bill of sale outside the exchange (their proceeds are taxable, usually at cost with little gain) so they do not contaminate the exchange or the excise tax base. Itemize them on the excise affidavit.
  • The permit does not follow you and does not need to; the exchange is about the real estate. But if you are exchanging into another short-term rental, the replacement property's permit path is the buyer-side diligence on the Washington STR laws page, and the replacement must satisfy the safe harbor for the next 24 months.
  • Depreciation carries over. The replacement property inherits your adjusted basis (plus any additional cash you put in), so the deferred recapture is embedded in the new asset and comes due when you eventually sell without exchanging, or is eliminated at death under current basis step-up rules.
  • Related-party purchases, reverse exchanges (buying first through an exchange accommodation titleholder) and improvement exchanges are all possible and all more complex; they need the QI and the CPA involved from the first conversation.

Checklist

1031 exchange checklist for a Washington STR seller

  • Confirm the safe harbor: 24 months of ownership, 14+ fair-rental days and personal use within the limit in each of the last two years.
  • Engage a qualified intermediary before listing; add exchange cooperation language to the purchase agreement.
  • Have your CPA compute gain, depreciation recapture and the reinvestment target (value, equity and debt) for full deferral.
  • Separate furnishings by bill of sale outside the exchange; itemize them on the excise affidavit.
  • Build the replacement shortlist before the relinquished property closes; identify in writing by day 45.
  • Close the replacement by day 180 and observe the 24-month safe harbor if it is a dwelling unit.

FAQ

Questions Washington STR sellers ask first.

Can I do a 1031 exchange on a vacation rental or Airbnb?

Yes, if it was held for investment. The IRS safe harbor in Rev. Proc. 2008-16 covers a dwelling unit you owned at least 24 months and, in each of the prior two 12-month periods, rented at fair rental for 14 or more days while keeping personal use to no more than the greater of 14 days or 10% of rental days.

How many days can I use my vacation rental and still qualify for a 1031 exchange?

Under the safe harbor, no more than the greater of 14 days or 10% of the days it was rented at fair value, in each of the two 12-month periods before the exchange. Days spent working full time on repairs and maintenance generally do not count as personal use.

What are the 1031 exchange deadlines?

You must identify replacement property in writing to your qualified intermediary within 45 days of closing the sale and acquire it within 180 days (or by your tax return due date including extensions, if earlier). The deadlines are calendar days and do not extend for weekends or holidays.

Does a 1031 exchange defer depreciation recapture?

Yes. A fully deferred exchange defers the capital gain, the 25% unrecaptured section 1250 gain on building depreciation and the ordinary-income recapture on cost-segregated personal property. Your adjusted basis carries into the replacement property, so the deferred amounts come due on a later taxable sale.

Can I exchange a Washington cabin into a rental near Seattle?

Yes, real property held for investment anywhere in the United States is like-kind to real property held for investment. Many owners exchange out of a vacation market with tightening permit rules into a long-term rental or small multifamily building in King, Snohomish or Pierce County, after checking Washington's 2025 rent-stabilization rules.
