Rental property income is income earned from rental real estate. If you own an investment property that is rented out to tenants, you will answer yes to the question "Did you receive any rental property income?" Please note that income from Airbnb rentals qualify as rental property income. 

There is a silver lining though...  If you had some rental income, it means that you can deduct costs associated with renting the property out.  Your Pro can help you identify deductions that will save you money on your tax bill.
