If your intention is to rent out the property again "and" you actually do rent out the property again once all work is complete, it's best to keep it classified as a rental. Otherwise, if you convert it to personal use, you will lose a lot of deductible expenses. For example, restoration is going to be using water and electric which *you* pay the bills for. Those expenses are not deductible for personal use property. But they are deductible for business/rental use property. So leave it classified as a rental.
There's nothing wrong with entering the actual number of days rented (and telling the truth) vs. saying it was rented the whole year. Now a part of your insurance payout was for lost rental income. Generally, that's for anywhere from 6 months to a year of rental income. You will include that amount of the insurance payout designated for lost rent, in the total rental income received for the entire year. Note that the insurance portion for loss of rent is typically for 85% of the actual rent, or less. That's common.
For your "days rented" and "days of personal use" questions, understand that vacant periods during the year (common between renters) do not count against you. However, personal use days *DO* count against you. Therefore, make sure you enter ZERO for days of personal use.
