How about we leave our taxation structure the same, and in that pie chart I posted (you saw that right?)

(Admittedly deferred taxation can be a substantial benefit) but still I don’t see real estate investing as being specifically favored by the tax code. 

S-Corp/C-Corp - as a general rule - you don't want to hold real estate in an C-Corp.If your vacation rental can be deemed ordinary income(if you provide items outside of solely renting a room such as bread and breakfast) - there may be some advantages of operating it as an S-Corp.If you have other owners in the LLC - you have the option of a partnership taxation or S/C-Corp.

If Denver generates enough income with Airbnb taxation, then other cities will fall in line.In the first six months of 2017, Denver collected just under $1 million in hotel tax from Airbnb and short-term rental hosts.

@Dan Heuschele  Even if your assessment is correct,  there are vast differences in pricing, price-to-rent ratios, taxation, and especially landlord laws. 

@Erin W.From a tax perspective - As a California resident - you are taxed on "worldwide income" meaning you have to report every income you earned to CA and pay tax on it.This can include W-2 wages earned through your employer, real estate investments in CA and even real estate investments out of state such as Texas.Normally - to offset the potential double taxation - California will give you a credit for taxes paid to another state.

While double taxation is in play for C corps, would it be to my advantage to orchestrate a C Corp (rather than other business structures) to reap the benefits of this tax reduction?

I am looking for recommendations for tax preparation professional with knowledge of cross-border (USA/CAN) taxation.

It changed to a blanket exclusion of taxation on the first $250K or $500K (single / married.) 

We tell our clients that if you hold your property for a year and a day from any point in time, you'll be in one tax year when you buy it, another when you sell it, and your property will qualify for 1031 exchange treatment.In a market of fast-appreciating property values, flipping property for a quick profit has its rewards, but you'll be paying tax at ordinary tax rates.
