Short-term rentals (like Airbnbs) can generate paper losses through accelerated depreciation, which can be used to offset active income, even if cash is being made.
"So, let's run the numbers. You buy the same property, you treat it like an Airbnb, and now you made $10,000 over the course of a year. Now, you have a lot more turnover. You have more work, but you made this $10,000. You take the accelerated depreciation. Let us assume that you get $20,000 worth of accelerated depreciation. That's the write- off on paper, which means you made $10,000, you have it in the bank, but you could tell the IRS that you lost $10,000 on paper."
