Can I exchange a long-term rental for a short-term rental?

Yes. Like-kind means real property for real property. An apartment building is like-kind to a vacation rental. The replacement property just needs to be held for investment or business use, not personal use.

What happens if I miss the 45-day identification deadline?

The exchange is disqualified and the full gain is taxable in the year of sale. There are no extensions except in federally declared disaster areas. The 45-day clock starts the day you close on the sale, not the day you list the property.

Can I do a 1031 exchange on a property I've been using personally?

It depends on the ratio of rental to personal use. The IRS safe harbor for vacation rentals requires at least 14 days of rental at fair market value per 12-month period and personal use limited to the greater of 14 days or 10% of rental days. Heavy personal use can disqualify the property.

Do I have to buy a more expensive property?

No, but you'll pay tax on the difference. To defer all gain, you need to reinvest all proceeds and replace all debt. If you buy down in value or take cash out, the difference is taxable boot.

Can I use a 1031 exchange to defer depreciation recapture?

Yes. Depreciation recapture is deferred along with capital gains in a 1031 exchange. The recapture carries into the replacement property's basis and is only triggered when you eventually sell without exchanging.

What is a reverse 1031 exchange?

In a reverse exchange, you buy the replacement property before selling the relinquished property. This is more complex and expensive (typically $5,000–$10,000 in QI fees) but useful when you find the right replacement property before you're ready to sell. The same 45/180-day deadlines apply, running from the date you acquire the replacement property.

The 1031 Exchange Playbook for Short-Term Rental Investors

A 1031 exchange lets you sell an investment property and roll the proceeds into a replacement property without recognizing capital gains at the time of sale. Done right, you can compound your portfolio for decades without a tax event. Done wrong, you miss a deadline and owe the IRS everything you were trying to defer.

Here's how it works, where STRs fit in, and the rules you need to know before you sign a purchase agreement.

The basics of Section 1031

Under IRC Section 1031, if you exchange real property held for investment or business use for "like-kind" real property, you don't recognize gain or loss on the exchange. The gain is deferred, not forgiven, and it carries into your basis in the replacement property.

Since the Tax Cuts and Jobs Act of 2017, Section 1031 applies only to real property. Personal property (equipment, vehicles, artwork) no longer qualifies.

"Like-kind" is broader than most people expect. An apartment building is like-kind to a vacation rental. A vacant lot is like-kind to a commercial building. Almost any U.S. real property held for investment or business is like-kind to any other U.S. real property held for investment or business. You can exchange a long-term rental in Ohio for an STR in Florida.

The timeline: two deadlines that matter

A 1031 exchange is not simultaneous. You sell first, then buy. The IRS gives you two hard deadlines:

45 days: From the date you close on the relinquished property, you have 45 calendar days to identify potential replacement properties in writing. No extensions, no exceptions.
180 days: You must close on the replacement property within 180 calendar days of selling the relinquished property (or the due date of your tax return for that year, whichever is earlier).

These deadlines run simultaneously. If you close on your sale on January 1, your identification deadline is February 15 and your closing deadline is July 1.

Identification rules

You can identify up to three properties without restriction (the Three-Property Rule). If you identify more than three, you must either:

Intend to close on properties whose combined value doesn't exceed 200% of the relinquished property's value (the 200% Rule), or
Actually close on properties representing at least 95% of the total identified value (the 95% Rule, rarely used)

Most investors use the Three-Property Rule. Identify your top three candidates and pursue the best one.

The qualified intermediary requirement

You cannot touch the sale proceeds. The moment you receive the money, the exchange is disqualified. You must use a Qualified Intermediary (QI), also called an exchange accommodator, who holds the funds between the sale and the purchase.

The QI must be in place before you close on the sale. You cannot set one up after the fact. Choose a QI with errors and omissions insurance and a track record, since the funds sit with them for up to 180 days.

Boot: what it is and how to avoid it

"Boot" is any non-like-kind property you receive in the exchange, including cash. If you don't reinvest all of the sale proceeds and replace all of the debt, you'll receive boot, and boot is taxable.

To fully defer gain, you need to:

Reinvest all net proceeds from the sale
Replace any debt on the relinquished property with equal or greater debt on the replacement property (or additional cash)
Take title to the replacement property in the same name as the relinquished property

Partial exchanges are allowed. If you take some cash out, you pay tax on that amount and defer the rest.

STR-specific considerations

Short-term rentals qualify for 1031 treatment, but there are two rules to watch.

The held-for-investment requirement. The relinquished property must have been held for investment or business use, not primarily for personal use. If you've been using the STR heavily for personal stays, document your rental activity carefully. The IRS looks at the ratio of rental days to personal use days.

The Rev. Proc. 2008-16 safe harbor. The IRS has a safe harbor for vacation rentals: if you owned the property for at least 24 months before the exchange, rented it at fair market value for at least 14 days in each of the two 12-month periods before the exchange, and limited personal use to the greater of 14 days or 10% of rental days in each period, the property qualifies. Meeting this safe harbor removes ambiguity.

The replacement property has a similar safe harbor: own it for 24 months after the exchange, rent it at fair market value for at least 14 days in each 12-month period, and limit personal use to the same thresholds.

Combining 1031 with cost segregation

Here's where it gets interesting. When you do a 1031 exchange, you carry your depreciation basis from the old property into the new one. If you took accelerated depreciation on the relinquished property, that recapture is deferred into the replacement property.

You can then commission a new cost segregation study on the replacement property and take another round of accelerated depreciation. You're not double-dipping: you're taking depreciation on the new property's components, which is entirely legitimate. Over a career of rolling exchanges, this strategy can generate substantial tax-deferred compounding.

What a 1031 exchange costs

QI fees typically run $800–$1,500 for a straightforward exchange. Add attorney fees if you need legal review of the exchange documents. The cost is modest relative to the capital gains tax deferred, which on a $500,000 gain could easily exceed $100,000 in federal tax alone.

When a 1031 doesn't make sense

Not every sale should be a 1031. If you have significant suspended passive losses on the property, selling outright may free those losses to offset other income. If you're in a low tax bracket, the capital gains rate may be 0% or 15%, making deferral less valuable. And if you're near the end of your life and your heirs will receive a stepped-up basis, holding until death eliminates the deferred gain entirely.

Run the numbers with your CPA before assuming a 1031 is always the right move.
