I need to patch and paint old nail holes. According to my lease, I'm moving out of my house and I'm responsible for the holes. Not typical, but hey its a nice place. I was wondering, do I need to repaint the entire wall? The house is about 3100 Sqft. Almost every wall has nail marks. The walls are clean, meaning I don't see an outline where the old pictures were. I plan on going to the paint store with a paint chip. I have been told that they have the technology to match it up pretty close. If I were to contract it out, watch price range should I be in?
