The STR loophole — converting passive losses to active

Normally, rental real estate losses are "passive" and can only offset passive income. But if you operate a short-term rental (average stay ≤7 days) AND materially participate, the losses become non-passive and can offset W-2 income.

The mechanics rely on a specific IRS regulation: when the average rental period is 7 days or less, the activity is not a "rental activity" for passive activity purposes — it's treated as a trade or business. If you then materially participate (typically 100+ hours and more than anyone else, or 500+ hours), losses can offset active income including W-2 wages.

Why it matters: a high-W-2-earner buys a $700K cabin, places it on Airbnb, runs cost segregation in year one ($150K+ of bonus depreciation), and shows a $100K+ tax loss — which offsets W-2 income at 32–37% marginal rates. The tax savings alone can be $30K–$40K in year one.

Risks: the IRS scrutinizes material participation tests; documentation matters; the property must genuinely be a short-term rental, not a long-term rental dressed up. And recapture at sale still applies. This is sophisticated; engage a CPA who has explicitly handled the STR loophole before you commit.

Short-term rentals (Airbnb) — the regulatory wildcard

Vacation rentals can generate 1.5–3× the gross of long-term rentals — but operating costs are higher, vacancy is higher (50–70% occupancy is normal), management runs 20–35% of gross, and regulatory risk is the biggest single threat to the entire investment thesis.

Depreciation — the biggest tax benefit of direct ownership

The IRS lets you deduct a portion of the building cost (not land) each year as depreciation — over 27.5 years for residential, 39 for commercial. A $300K building generates ~$10,900/year of deductions. At a 32% marginal rate, that's $3,500/year in tax savings even before any other deduction.
