I'm considering selling one of my underperforming STR properties and using a 1031 exchange to buy a better one in a different market. But I've heard 1031 exchanges for STR are complicated — something about "personal use days" disqualifying you? Can someone walk me through how 1031 exchanges work specifically for Airbnb/STR properties? What are the gotchas that could disqualify me?

1031 exchanges for STR absolutely work but there are specific pitfalls that can disqualify you. I'll walk through it. The concept is simple: sell an investment property, buy a "like-kind" replacement, and defer all capital gains taxes. You're not avoiding taxes permanently — you're deferring them until you eventually sell without exchanging. (Or you die, at which point your heirs get a stepped-up basis and effectively pay nothing. Morbid but useful tax planning.) The STR-specific gotcha everyone needs to know about: personal use. The IRS requires the property to be held "for investment or business use." If you use it too much personally, they might classify it as a personal residence and that does NOT qualify. The safe harbor rules say that for the 2 years before selling, you need to have rented it at fair market rate for at least 14 days per year, and your personal use can't exceed 14 days or 10% of total rental days, whichever is greater. So if you rented it 200 days and used it personally 15 days, you're fine because 15 is less than 20 (10% of 200). Same rules apply to the replacement property for the 2 years after purchase — don't buy something with a 1031 and immediately start using it as your vacation home. The timeline: you sell your property (day 0), identify up to 3 potential replacement properties within 45 days (written notice to your Qualified Intermediary), and close on the replacement within 180 days. Those deadlines are hard — no extensions, period. The process requires a Qualified Intermediary (QI) that you hire BEFORE listing your property for sale. The QI holds the sale proceeds — you never touch the money. When you close on the replacement, the QI transfers the funds. The replacement property must be equal to or greater in value than what you sold. Any cash you take out ("boot") is taxable. Common mistakes I've seen people make: touching the funds even briefly (exchange fails immediately), not having a QI in place before closing, exceeding personal use limits before selling, missing the 45-day identification deadline, trying to exchange into a primary residence, or buying a property they plan to use as a vacation home. Cost is reasonable: QI fees run $600-1,200, legal review another $500-1,500. So $1,100-2,700 total to potentially defer $30-80K+ in capital gains taxes. This is NOT something to DIY.
