I think what would help would be siting the section of the official source.
Did you yet notice the nolo site you referenced doesn't cite their source? There's a reason for that. They're getting their information from IRS Publication 535 which applies to a SCH C business or an incorporated business that produces "earned" income. There is no mention, reference or even an insinuation in that document of it applying to a passive business - which is rental property.
That information has been on the nolo site for more than 5 years, and it's their interpretation of the IRS regs - which I might add are regs that do not apply to passive activities. Rental income is passive (with some exceptions which the likes of you and I don't meet or qualify for.)
If you "go there", you can fully expect an audit about 24-36 months after you file. Generally it's a paper audit done by mail, where the IRS "corrects" your tax return, notifies you of their correction and the additional amount of tax/fines that you owe. The letter gives you 30 days to either pay or provide supporting documentation to validate your claim. You'll pay because "supporting documentation" just doesn't exist.
Go their at your own risk and peril.
