I wouldn't hold a space for a year. However, I have a family in care now and the oldest child goes to JK in Sept. Then they are paying $200/month as a holding fee until their baby starts with me in Jan before the Mom returns to work in Feb. This family is a wonderful client and longer than I would consider having a space remain empty for anybody else. I think you answered your own question in your last post when you said they have caused you problems, so it's better if you get a new family in the space.
