First off, don’t move into a place you don’t like the feel of unless you want to put in shit tons of work on it magically and physically.
Second, when you move into a new place, put up your basic furniture, and then most of your shrine, magical, altar stuff really early on in the move, like first day. I always pack my spiritual stuff last and unpack it first (right after the basic furniture.
Third, buy a new broom. Don’t bring your old broom. I mean like your sweeping broom, not your besom (if you have one). Its fine to bring your same magical besom, imho, but just get rid of your old broom, or at least get rid of the brush on it and put a new one on. If you use a straw broom like mine, you can even compost the old one. If you cannot even do that, please for the love of good, clean the hell out of your old broom.
Fourth, make a new magical charm, sigil, house doll, or what have you for your new place. I made a new house protection charm and put it up as one of the first things. Put up all your usual protections.
Fifth, keep moving in, unpack your stuff, get comfortable. If you notice any hot spots that need treatment attend to them. Houses have histories and stories and I don’t like to completely erase them like wiping a computer harddrive. I like to work with what the house has and build on it.
