As another commenter pointed out - most tax incentives for living in a home you own do not apply to investors. Investors get those benefits "for free" because they are a business and all the costs of running a business are deductible. The incentives you speak of actually puts regular folks on a more even footing as corporate folks.

Stuff like bonus depreciation - yeah, let's get rid of that. Or 1031 exchanges. Regular folks cannot benefit from it.

Companies are charged taxes on their profits. The interest on money borrowed in furtherance of a business is just like any other business expense: deductible.

The owner-occupied mortgage interest deduction serves to put owner-occupants onto the same footing as businesses; it’s not an incentive that gives them preference, but rather (closer to) equal footing.

Then people would decry socialism, big government, or excessive regulation.

Who are "people?" Is this where we hate for a few minutes on libertarians? Republicans? The unwashed American majority? Emmanuel Goldstein?
