I just re-read your original post. You indicate you converted it to a "part time" rental. The IRS term for that is "short term rental". If your intention is to rent it for less than one year, then it's a short term rental and personal use days for the entire tax year, regardless of your date of conversion, do count against you. Your allowed rental expenses including depreciation will be reduced based on the number of days you lived in the property at any time during the tax year.
If you are going to be converting the property between personal use and rental use each year, this creates it's own nightmare for you down the road. When a personal use property that was once rental use is converted back to a rental, you have to reduce the cost basis of the depreciable assets (which does not include the land) by the total amount of depreciation already taken in the past, and depreciation starts all over from that new cost basis. This means the amount of depreciation taken each year will be different, and reporting the sale or other disposition of the property in the future has the potential to be a mental and mathematical nightmare. In most cases, the TTX program can't handle the situation automatically, and requires the user to manually "do the math", thus increasing the possibility of user error.
