For how many days a year or less must an investor live in a vacation home to qualify for depreciation?

To qualify for depreciation on a vacation home, the IRS stipulates that the homeowner must not use the property as a personal residence for more than 14 days or 10% of the total days the property is rented out, whichever is greater. This means that if someone lives in their vacation home for 14 days or fewer throughout the year, they can then categorize it as an investment property. By doing so, they are eligible to take advantage of tax deductions related to depreciation. This provision helps reinforce the distinction between personal use and rental use, enabling property owners to benefit from their investment while ensuring compliance with tax regulations. Thus, the answer is indeed 14 days.
