Just to present an alternative point of view regarding California residents investing in STRs, I'd say the gambit still works and works well.For one thing, you still get to use the Section 263(a) tangible property regulations' de minimis rules, which probably mean you can immediately expense most of the furniture and fixtures in your STR.For another thing, while for your California return you won't be able to use bonus or accelerated depreciation for the personal property, you will still use shorter 5-year and 7-year lives for maybe 25% of the improvements.But the big thing: The federal tax bill is far, far bigger.
