I just bought an old house and we're going to paint the entire interior. It's a small house, 6-7 rooms, but plenty of trim and details. I've painted rooms before but never an entire interior like this. I'm really struggling with the decision to paint myself (with help from friends of course) or to shell out money to have a professional do it. It's expensive to have a pro do it but time consuming to do it myself. Any advice out there?
