We bought our house in February 2006. The house was seven-years-old. The inspector asked if we wanted the septic tank inspected. It would cost $100. He said that most people who buy a house this new don’t have it inspected b/c there’s usually nothing wrong. Well, I’m paranoid, so we had the inspection. It’s a good thing we did, b/c the darn thing FAILED the inspection, and the whole drain field had to be replaced by the sellers before we bought the house. It cost them about $7,000. 🙂
