We bought one of our homes in December, and were able to start moving in on Dec 24th. We had no furniture, but I wanted a tree. We went to a local lot and told them we were just moving in and needed a tree. They surprised us by giving us the tree as a housewarming gift! We decorated it with ornaments we'd brought with us. We had that tree and nothing else in the house except our suitcases and sleeping bags, but we loved it!
