Cleansing my new house of the previous owners shitty energy

I’ve been out of practice the past few years since having my kid. I’m in the process of buying a house and the current owners are being absolute fucking assholes about everything, to the point that I almost walked away from the house today. Assuming this does end up going through, I’d love any energetically cleansing rituals or maintenance to 1. Remove their energy and 2. Create my own. I have a few things I will for sure be doing (smoke cleansing, hanging bells at doors, setting up my kitchen witch windowsill herb garden), but any other rituals would be welcome! I typically do kitchen/green/tarot practice
