Short-term rental economics in 2026 come down to three numbers: occupancy, nightly rate and the cost of staying legal. AirDNA's midyear outlook, published July 8, 2026, forecasts U.S. short-term rental occupancy of 57.4% for the year, slightly above the 57.0% pre-pandemic average, with revenue per available rental rising 2.9% as nightly rates accelerate from 0.7% growth in January to about 3% by spring [1]. The competing long-term option is not weak: the typical single-family home asked $2,280.91 per month as of June 30, 2026 [2]. Whether a furnished nightly rental beats a 12-month lease depends on the market, the rules and the owner's time.
Occupancy and rate: what the 2026 market looks like
AirDNA reports that demand and available listings are both projected to grow 2.7% in 2026, so the market is in balance rather than oversupplied [1]. Slower supply growth is giving established operators pricing power: the strongest revenue per available rental gains so far this year were in San Francisco (+12.1%), Anaheim (+11.0%) and Philadelphia (+10.1%), each a market where supply tightened [1]. The soft spot is inbound travel; international short-term rental demand ran 12% below the prior spring, with demand from Canada down 32% from 2024 [1]. Markets that depend on foreign visitors carry that risk; drive-to leisure markets do not.
An occupancy rate of 57.4% means a typical listing is empty 155 nights a year [1]. Revenue therefore depends on the rate charged on the other 210 nights, and on how many of those fall in peak season. A long-term lease has no such seasonality, which is why lenders underwrite long-term rent and treat nightly income as a bonus.
A worked comparison: nightly versus monthly
Take the typical U.S. single-family home, valued at $369,987 in June 2026 with a long-term rent of $2,280.91 per month, or $27,371 per year, according to Zillow-based data on DataPorium [2]. To match that gross income at 57.4% occupancy (about 210 rented nights), a short-term rental would need an average nightly rate of about $131. That looks easy until costs are counted. The figures below are illustrative assumptions used to show the mechanics, not measured data.
| Item (annual, illustrative) | Long-term lease | Short-term rental |
|---|---|---|
| Gross rent at $131 per night, 210 nights | $27,371 [2] | $27,510 |
| Cleaning, supplies, utilities, platform fees, furnishing reserve (assumed 40% of gross) | Utilities paid by tenant | $11,000 |
| Management (assumed 8% long-term, 20% short-term) | $2,190 | $5,500 |
| Income before taxes, insurance and mortgage | $25,181 | $11,010 |
| Nightly rate needed to match the lease after costs | n/a | about $300 |
Under those assumptions the nightly rental has to charge more than twice the break-even rate before it beats a lease, because the owner absorbs costs that a long-term tenant would pay and because turnover happens every few days rather than every few years. Markets where that is possible exist, mainly resort towns and event cities, and they are also the markets where local rules are tightening.
The mortgage still has to be paid every month
The 30-year fixed mortgage averaged 6.67% in the week of August 13, 2026 [3]. Zillow-based data put the principal and interest payment on a typical home with 20% down at $1,859.59 per month in June, and $2,462.14 with taxes and insurance [2]. That payment arrives in January whether or not guests do, so a short-term rental needs a cash reserve that a leased property does not.
Regulation costs: the rule set decides the market
The largest cost in short-term rental economics is often not a fee but a prohibition. New York City's Local Law 18 created a registration system and allows a legal short-term rental (under 30 days) only when the host lives in the same unit with the guests, guests have access to the full unit and no more than two guests stay at a time, not counting children under four; hosts may not rent an entire apartment or home for fewer than 30 days, and rent-regulated and public housing units cannot be registered at all [4]. For an investor who does not live in the property, that is a zero-revenue rule.
Denver defines a short-term rental as a dwelling unit available for one to 29 days and licenses it only as the applicant's primary residence, meaning the place where the person's habitation is fixed and to which they usually return; an applicant may hold one primary residence, and initial reviews take up to 30 days with specialist reviews up to 90 days [5]. Many cities have adopted variations of the same model: primary-residence limits, night caps, registration numbers on every listing and platform liability for unregistered units.
- Check the rule set before the purchase, not after: the difference between a permitted and a prohibited unit is the entire revenue line.
- Budget for licensing time as well as money; a 90-day review is three months of carrying cost at $2,462 per month for a typical home [2][5].
- Assume rules tighten rather than loosen; a property that works only as a nightly rental has no fallback if the license lapses.
- Prefer properties that also cover the mortgage as a long-term lease, which DataPorium's housing market data shows by metro, city and ZIP code [2].
Taxes: the 14-day rule and the personal use test
Federal tax rules add a second layer. A dwelling counts as a residence for the year if personal use exceeds the greater of 14 days or 10% of the days it is rented at a fair price; when that happens, rental deductions are limited to rental income and expenses must be split between rental and personal days [6]. At the other extreme, a home rented for fewer than 15 days in a year need not report the rental income at all and cannot deduct rental expenses [6]. Owners who use the property themselves for vacations should track days carefully, because the test changes which expenses are deductible.
From a market-oriented view, clear and simple rules serve owners and neighbors better than blanket bans: registration with modest fees and enforceable nuisance standards preserve housing choice while protecting residents. The fair counterpoint is that whole-home nightly rentals do remove units from the long-term market in tight cities, which is why the strictest rules appear where vacancy is lowest.
A short-term rental is a small hospitality business with a mortgage attached, and its return depends as much on the local rule book as on the nightly rate.
Key takeaways
- AirDNA forecasts 57.4% occupancy and 2.9% growth in revenue per available rental for 2026, with demand and supply both up 2.7% [1].
- A typical single-family home rented long term for $2,280.91 per month in June 2026; matching that after short-term costs requires a nightly rate near $300 under illustrative assumptions [2].
- New York City bars whole-unit rentals under 30 days, and Denver licenses only primary residences, so the rule set can eliminate the investment case before pricing matters [4][5].
- The 30-year mortgage averaged 6.67% in mid-August 2026, and the payment on a typical home is due regardless of bookings [2][3].
- The IRS 14-day and 10% personal-use test determines whether rental losses can exceed rental income [6].
Frequently asked questions
What is the average Airbnb occupancy rate in 2026?
AirDNA's July 2026 midyear outlook forecasts U.S. short-term rental occupancy of 57.4% for 2026, compared with a pre-pandemic average of 57.0% [1].
Is a short-term rental more profitable than a long-term rental?
Only when the nightly rate is high enough to cover turnover costs, furnishing, utilities and higher management fees. In the illustrative example above, matching a $2,280.91 monthly lease required roughly $300 per night at 57.4% occupancy [1][2].
Can you rent out a whole apartment on Airbnb in New York City?
No. Under Local Law 18, hosts may not rent an entire apartment or home for fewer than 30 days; legal short stays require the host to be present, with a limit of two guests, and the unit must be registered with the city [4].
How many days can I use my vacation rental before it counts as personal use?
The property is treated as a residence if personal use exceeds the greater of 14 days or 10% of the days it is rented at a fair rental price, which limits deductions to rental income [6].
