To declutter effectively on a budget, start by removing personal items, excess furniture, and knickknacks from every room. Pack up family photos, souvenirs, and collectibles to depersonalize the space and create a blank slate. Clear countertops, shelves, and tables to emphasize clean surfaces and open areas. Use simple storage bins or boxes you already own to temporarily tidy items out of sight. Decluttering creates a sense of spaciousness and calm that buyers love and costs nothing but effort.
