Can you explain this please? Excuse my ignorance of the US tax system.
This sounds like a pretty shitty thing for the government to allow, giving existing home-owners a huge advantage to build up property portfolios over people not yet orable to get on the ladder. (similar to negative gearing in Australia where I live)
In a fair world, this would only be allowed on the first buy-to-let property. Anything above that is just not in the interest of society in general, especially in cities like SF and Sydney that are running out of space to and/or NIMBY behaviour.
The detailed reality is a bit more complicated of course (there are rules specific to real estate) but that's the essence.

The intention is the incentivize people to own their own home, it is not to incentivize them to build up property portfolios. Indeed that would be perverse.
I'm sure you can show a loss on an investment with real estate just like you can with any investment but I think continuing to buy subsequent houses and showing losses on all of them as part of your personal tax returns might raise some flags.
That is not correct. The article you posted seems to imply it, but it is absolutely not true.
Pure rental property is treated as a business property, and mortgage interest on business properties is an expense that is deducted from rental income before determining tax liability. You can even carry a net loss over to your personal return (subject to some limits).
Details in IRS pub527: https://www.irs.gov/publications/p527/ch01.html
For instance if you have bought a property as a pure investment property and the total mortgage + interest is being covered by the tenants monthly rent. You can not then write off that interest at 100% since you are not actually incurring that interest payment yourself correct?
We weren't discussing a company though, we were discussing one's personal income tax filing.
Mortgage interest is itemized just like any other cost incurred, e.g. maintenance, utilities, advertising, property taxes, etc.
The net profit/loss on the Schedule is then applied to your personal return. You might be limited in the size of loss you can apply, but that's an unrelated calculation.
Can you elaborate ?
