I thought it was an actual loss.

But is that a $100 "loss"?

Quote from @Santos Lopez: I heard that there's a way to deduct short term rental losses against earned income (e.g.

I have never sold at a loss.

That may apply to personal deductions (like mortgage interest), but rental expenses (repairs, depreciation, etc.) are taken on Schedule E and are not affected by whether you itemize or take the standard deduction.

Tenant agrees to maintain all furnishings, furniture, décor, and household items in good condition and to use them only for their intended purpose.

I sold the Class C with a capital loss and am selling the other Class C, both bought in 2023.

Under IRS rules, a property qualifies for the STR loophole if the average guest stay is seven days or less, This allows rental losses including depreciation, to offset W-2 or other active income without needing REPS.

These kind of losses are unsustainable.

If it is active, you can use the rental loss(Expenses in excess of income) against your other form of income such as wages, interest, dividends, etc.
