Why average guest stay changes the tax category
Under longstanding tax rules, a rental activity where the average guest stay is seven days or less is generally treated more like a trade or business than a passive rental activity for certain purposes -- which is part of why short-term rentals can unlock loss treatment that a typical long-term rental doesn't.
That reclassification alone doesn't automatically make losses deductible against other income, though -- it opens the door, it doesn't walk through it.
Material participation is the second door
To actually use short-term rental losses against other income, the owner generally needs to meet a material participation standard -- a specific number of hours and a specific level of involvement, documented, not assumed.
