Investors & landlords

The period of time you live in the property as either your primary residence, 2nd home or any other personal use *while it is classified as a rental* does have to be accounted for, in that you would not have 100% business use then. Just understand that it's difficult to tell you if the period when it's not classified as a rental, counts or not. You'd need to read IRS publication 527 at https://www.irs.gov/pub/irs-pdf/p527.pdf starting on page 17. There's an example there that provides a scenario of when "all" personal use during the tax year *does* count. That very well may apply to you. So please read that section to help you make that determination.
