Investors & landlords

It was a rental for the whole year.  I (and probably others also with this same question) just need to know what they're asking for when they put 'Rental Use Percentage' and a box to put a percentage.  Even without my specific situation, surely it must mean either it was rented out 100% of the year, or not.  I'm not sure if by putting 100% in the box it means I lived in it 100% of the time, or if it means that it was rented out 100% of the year.  That's all. Thanks for helping me with this question.
