Buying an STR in November or December: Can You Still Qualify This Year?

You closed on a short-term rental in November. Your CPA is already hinting the losses will be passive this year because you "barely had time to do anything." They might be right. They might also be leaving real money on the table.

Late-year STR purchases sit in an awkward gray zone. The tax benefit is theoretically available the moment you place the property in service — the IRS does not require you to own something for 12 months before the loophole kicks in. But two tests stand between you and those non-passive losses, and both get harder when your ownership window is measured in weeks rather than months.

TL;DR: Yes, you can qualify for the STR loophole in the same year you buy, even with a November or December close. You must still meet the 7-day average stay rule under Treas. Reg. §1.469-1T(e)(3)(ii)(A) AND a material participation test (most commonly: more than 100 hours AND more than anyone else). The IRS does not prorate the hours threshold for partial-year ownership. Whether it's realistic depends on how quickly you list the property, how you structure bookings, and how hands-on you are from day one.

Yes, You Can Still Qualify — Here's What Has to Be True

The STR loophole works like this: a rental whose average guest stay is 7 days or less is not treated as a "rental activity" under IRC §469. That one reclassification means the passive activity loss rules no longer apply. If you also materially participate in the property, the losses are non-passive and offset your W-2 or other ordinary income directly.

Neither of those two requirements has a "must own for a full year" clause. What matters is what happened during your ownership period in that tax year.

So the question isn't whether the loophole is theoretically available. It's whether you can honestly satisfy both tests with the time that remains on the calendar.

The 7-Day Average Stay Rule With Limited Bookings

The average period of customer use is calculated as total rental days divided by total number of rentals for the year. Under Treas. Reg. §1.469-1T(e)(3)(ii)(A), that average must be 7 days or less for the property to fall outside the passive rental rules.

When you only have four to eight weeks on the clock, each individual booking carries enormous weight in the calculation.

Say you close on November 15 and take four reservations before December 31: a 3-night stay, a 4-night stay, a 5-night stay, and a 2-night stay. Total rental days: 14. Total stays: 4. Average: 3.5 days. You're well under the 7-day threshold. Good.

Now say you also accept a single holiday week booking — 8 nights. Your numbers become: 22 total rental days across 5 stays, average of 4.4 days. Still fine.

But if you accept a 14-night stay because December is slow and someone wants the property for two weeks, your average climbs fast. Even with three short stays alongside it, one long booking can flip the math. With a compressed booking window, you have less margin to absorb a long reservation without blowing the average.

The practical fix: in November and December, keep your minimum stay at 7 days or under and do not accept extended bookings unless you have enough short stays to keep the weighted average below 7. This isn't about gaming the system — it's about understanding that your average stay is a real mathematical test you must pass annually, and that test is more fragile when you have fewer data points.

The Material Participation Hurdle in a Short Ownership Window

Here is where a lot of late-year buyers get tripped up. The IRS does not prorate the 100-hour test to your ownership period. You still need to log more than 100 hours AND more than anyone else who worked on the property — cleaners, co-hosts, property managers — during the portion of the year you owned it.

That is a real lift in six to eight weeks. Is it impossible? No. Is it automatic? Definitely not.

Think about what actually happens when you buy a new short-term rental in November:

• You're coordinating with contractors, cleaners, and stagers to get the property ready.
• You're building the listing, writing descriptions, setting pricing, photographing or directing photos.
• You're handling guest inquiries and first bookings directly.
• You're on-site for setup trips, inspections, and possibly the first guest turnover yourself.

A hands-on owner doing all of that personally can realistically log 100+ hours between mid-November and December 31. But "realistically" only counts if you document it. Every hour needs a date, a specific task description, and a start and end time — logged contemporaneously, not reconstructed in February.

Tax Court has been clear on this. Estimates written after the fact lose (Almquist v. Commissioner). Rounded hours with no times lose (Penley v. Commissioner). "On call" time does not count. The log has to reflect what you actually did, when you did it.

Tools like the STR Loophole app make this easier by logging tasks in real time, so you're building the record as you go rather than scrambling before you file.

If you also need to beat your cleaner's hours: that means you personally need to log more time on the property than whoever cleans it between guests. A cleaner doing four turnovers at 3 hours each has 12 hours logged. You need at least 13, plus the 100-hour floor. The more turnovers in a compressed window, the tighter that margin.

To see how the two most common participation tests compare and which makes more sense for a partial-year situation, read 100 hours vs. 500 hours for the STR loophole.

A Worked Example: The November Close

Let's run the numbers on a realistic late-year scenario so you can see what's actually possible.

Assumptions:

• Close date: November 10
• Purchase price: $420,000 (land value: $70,000, depreciable basis: $350,000)
• Cost segregation reclassifies 30% of depreciable basis into 5- and 7-year personal property: $105,000
• Remaining basis: $245,000 depreciates over 39 years (commercial) or 27.5 years (residential), depending on classification
• You take 100% bonus depreciation on the $105,000 of reclassified property under IRC §168(k) as restored by the One Big Beautiful Bill Act
• Net rental income for November–December: $4,200
• Operating expenses (insurance, supplies, cleaning fees, utilities): $3,100
• Paper loss before depreciation: minimal ($1,100 net income)
• After 100% bonus depreciation of $105,000: paper loss of approximately $103,900
• Your marginal federal tax rate: 32%

Tax impact: $103,900 loss × 32% = $33,248 in federal tax savings — offset directly against your W-2 income, in the same year you bought the property.

That's the power of the STR loophole paired with cost segregation and current-law 100% bonus depreciation. The property existed in your portfolio for less than two months, and it generated a six-figure paper loss available in year one.

Two important clarifications: First, the 100% bonus depreciation rate applies because the property was acquired after January 19, 2025 — current law under the One Big Beautiful Bill Act makes this permanent for qualified property. Second, this math only works if you satisfy both the 7-day average stay test AND material participation. If either test fails, those losses are passive, and they sit suspended until you have passive income or sell the property.

What "Placed in Service" Actually Means

One timing detail that trips people up: bonus depreciation and the loophole both require the property to be placed in service in the tax year, not just purchased.

"Placed in service" means ready and available for its intended use. For an STR, that generally means the property is listed and available for guest bookings. A property you closed on in November but didn't list until January is placed in service in January — no year-one depreciation benefit, regardless of when you signed the deed.

The practical implication: list the property the moment it is guest-ready. Even if you don't have bookings yet, available-for-rent status establishes your placed-in-service date. Keep a record of when the listing went live.

Tracking Hours From Day One

The biggest mistake late-year buyers make isn't failing to qualify — it's failing to document. They assume that if they do the work, the hours will be obvious later. They won't be. After-the-fact reconstruction is exactly the paper trail that loses in Tax Court.

Start logging on closing day. Setup trips, vendor calls, listing builds, guest messages, pricing research — it all counts if it's related to the activity and logged correctly.

Our post on starting your STR tracking mid-year covers the mechanics of picking up a log partway through the year, including how to handle the gap between contract and close. For a broader look at what qualifies under each material participation test, see how to qualify for the STR tax loophole.

When It Makes More Sense to Wait for Year Two

Honesty time: not every late-year purchase is worth chasing year-one qualification. If you're closing December 20, the property needs two weeks of renovation before it can host guests, and you live three states away — the math is not in your favor. You are not going to hit 100 hours. You are not going to have an average stay built on enough bookings to be defensible.

In that case, the right move is to document carefully, treat year one as a partial year with passive losses that carry forward under IRC §469, and start year two clean with a full calendar, a cost segregation study already done, and a time-logging habit already in place.

Suspended passive losses don't disappear. They carry forward indefinitely and offset passive income in future years, or they release entirely when you sell the property. A careful year two is worth more than a strained year one that invites scrutiny.

Key Takeaways

• The STR loophole has no minimum ownership period. It applies in year one if you meet both tests.
• The 7-day average stay rule is more fragile with few bookings. Watch long reservations carefully.
• The IRS does not prorate the 100-hour material participation test for partial-year owners.
• 100% bonus depreciation under current law (post-OBBBA) applies to property acquired and placed in service after January 19, 2025 — regardless of how late in the year you close.
• "Placed in service" requires the property to be listed and available for guests, not merely purchased.
• Contemporaneous time logs are non-negotiable. Start on closing day.
• If the numbers don't add up honestly, carry the losses forward and plan properly for year two.
