Material participation is what converts a loss from passive to non-passive. Clearing the seven-day average stay test removes the automatic rental classification under Section 469. It does not by itself make the loss usable against wage income. For that, the owner has to materially participate under one of seven tests. This is where it stood in 2023, which was the year the market cooled and underwriting started to matter again.
What 2023 changed
2023 was the correction. Rates stayed high, supply that had been added during the boom arrived on the market, and occupancy in several previously unstoppable markets came down. The phrase that circulated was Airbnbust, which was overstated, and the underlying shift was real: revenue per property fell in markets where supply had grown fastest.
The spread between well-run and poorly-run properties widened sharply. In a market where everything fills, operational quality is invisible. In 2023 it was the whole difference.
Bonus depreciation stepped down to 80% for property placed in service in 2023, the first year of the TCJA phase-down.
How it works

- More than 500 hours of participation in the activity during the year.
- Participation constituting substantially all of the participation by all individuals, including paid managers and cleaners.
- More than 100 hours, with no other individual participating more, which is the route most W-2 earners actually take.
- Four further tests covering significant participation activities, prior-year participation, personal service activities, and a facts and circumstances test.
What that meant in 2023 specifically
With bonus depreciation at 80%, a cost segregation study still produced a large first-year deduction, and the arithmetic changed enough that the study cost had to be weighed more carefully on smaller purchases.
The properties that got into trouble in 2023 were bought at peak prices with thin reserves in markets that were absorbing new supply. None of those three alone was fatal. Together they were.
2023 rewarded buyers who could underwrite honestly and walk away. Basis mattered more than it had in years, because there was no longer a rising tide to cover an overpay.

Where it goes wrong
The failure modes are consistent across years, which is itself useful information: they are not caused by the market cycle, so a different year does not protect you from them.
- Handing everything to a full-service manager, which frequently defeats the 100-hour test because the manager participates more than the owner.
- Reconstructing a participation log in April rather than keeping one contemporaneously.
- Counting investor-type activities such as reviewing statements in a non-managerial capacity, which are specifically excluded.
What a buyer should have done in 2023
2023 rewarded buyers who could underwrite honestly and walk away. Basis mattered more than it had in years, because there was no longer a rising tide to cover an overpay.
The underwriting discipline does not change with the year. Twelve individual monthly revenue figures from a comparable set you assembled, a complete expense stack including reserves, and a stress test at 75% of projection that still covers debt service.
We screen roughly a thousand deals a week and eliminate about 98% of them. That ratio has held across every year on this site, through the boom, the correction and the stabilisation, because it is a function of how listings are selected rather than of the market.
What generalises, and what does not
Reading a year in isolation is the most common analytical error in this business. 2023 had its own conditions, and someone who learned the wrong lesson from it carried that lesson into a market that no longer rewarded it.
What generalises is the mechanics above. The definitions, the tests, the sequence and the failure modes are the same in every year on this site, which is why they are worth learning properly once rather than relearning each cycle.
What does not generalise is the environment: the cost of capital, the depth of supply, the bonus depreciation percentage, and the regulatory posture of a given jurisdiction. Those change, sometimes abruptly, and a model that treats them as fixed is a model that was only ever right about one year.
The practical consequence is to build the analysis so the environment is an input rather than an assumption. A property that only works at one interest rate, one occupancy level and one tax treatment is not an investment thesis, it is a bet that nothing moves.
