Re: Moving to a new house and 18 month old to own room?
I think you could set up the new room, at least somewhat, and start transitioning her in there. We've had DD sleep in her room for the first portion of her sleep (anywhere from 20 minutes to 3 hours, usually!) since she was about 6 months old. We just got her a double bed, and I've been staying with her until she falls asleep, and then I go to do chores and chill out until she wakes up (again, 45 minutes one night, 2 hours the next). We've had some success (easier with naps), but also illness and starting daycare at the same time, so she just came to bed with me last night when she was upset. If you have the space, I think it's nice to introduce kids to the idea of their own room and own bed, even if they don't take to it right away and even if you keep co-sleeping the whole time.
