Seriously, December? Or Sept '12??? WOW. Unless wait lists are insanely long where you are, that seems..... excessive. Lol
Anyway, honestly I think it depends on what you are comfortable with, and can afford. I also run under capacity, for a couple reasons. It allows me to take in part timers, when and how often I want. It also means that in the summer, when my kids are home from school, I am not running an illegal operation!
However, if I knew that I needed to fill x-number of spots to maintain my income at a certain level, and we were dealing with one of those spots I would absolutely charge someone to "hold" a spot. It would be non-refundable, if they chose not to take the spot, tough. I would not apply it to fees in the future, because I could have filled that spot immediately and had my full income.
In this case, I would probably go ahead and interview. But let them know that I was NOT guaranteeing a space. I would call them if that spot had not filled by a specific date.
Then again, you said that you don't really NEED that income, so perhaps you can be a little more flexible if you get a good feeling from this family. Sometimes, we gotta bend the rules a little!
