Congrats on your new home. I know how it can be exciting and overwhelming all at the same time. My kids were 1 yo and 2 1/2 yo when we moved into our new house. Luckily, they didn't seem to have any sleep problems during the transition. We tried to keep things familiar for them. We used nightlights nad played their lullabyes. We made sure they had their favorite blankets/stuffed toys to cuddle with. We also tried to make my 2 1/2 yo have a little bit of control by allowing him to decide every night if he wanted the door open all the way or part way.
I would recommend finding a way to get your daughter to fall asleep in her room so you don't have to figure out how to break that routine later on. What about a sticker chart to reward her - with a special treat or activity after a whole week of sleeping in her own bed? Or maybe allow her to pick a special poster, angel, or family photo to hang on the wall to "keep her company" while she is in her room? If you have plans to redecorate her room and get rid of the "bugs", could you consider doing so sooner rather than later?
