@Carl It is a vacation home in Arizona. It's usually rented between Nov-Mar, used for some personal days in April and October. Between May-Sept the weather is too hot, there is no rental market and no desire to have any personal days during that time.
If the form 4562 only allows for one conversion date then I guess it's not possible to do it the way I wanted to. I will have to do the ratio of personal days to rented days and take the depreciation for the whole year. I was hoping to minimize the depreciation by converting it to personal from April-October but it looks like this is not possible.
