Dear Robert Lee: I am new to visiting this site but it is proving to be very valuable. Here's my situation. When I moved into my apt they replaced all kitchen appliances, toilet, carpet, blinds, and painted the entire apt. Would this qualify as renovation, and changing the period? If so, what benefit would it have on a person who should live in a S facing apt but lives in a NE facing apt? And please explain the significance of having 3 celebrations. I appreciate your input. Lisa
