I am wondering, is that the most Tax efficient way moving forward as I purchase more properties and forms more LLCs?

As a CPA who works mostly with real estate investors and syndicators, here’s the quick version:From a tax standpoint, an LLC itself doesn’t lower your taxes — it mainly provides liability protection and separates your business from your personal assets.

Corp tax rate is 21% (although second tax on dividend distributions can undo any tax savings or even end up as a tax penalty).  

Check for possible transfer taxes, title insurance updates, or insurance changes.

Seriously, the whole strategy hinges on proving Material Participation so you can claim those juicy tax losses against your active income.

With pass through entities, there are no tax benefits, so there's that.

That's not necessarily true, if you file an LLC as an S-Corp you can save some tax liability on self employment taxes.

Louis property makes sense for liability and local operations.

For liability, use one property per LLC (or at least separate higher-risk assets) so a lawsuit on Property A can’t reach Property B.

If one has a second home in a high-tax state that rents for more than 14 days a year and is used more than 14 days, would it make sense to convert it to a rental property, given the new tax law?
