I don't think anybody likes to think about whats in their sewer line. In fact, most buyers never even think about it. But I have bought a number of foreclosures and often there are things in the lines that can cause problems down the road if not fixed. I can remember at least 6 times I needed to call my dude Brad up to clean out lines on my properties. I think it is worth getting a sewer line inspection. Its only $180 and if the line was clogged and it gets cleaned it out, it might end up saving you from having a wet basement. If the line gets clogged the drain can back up and start to flood the basement. Hit me up if you need Brad's number or have questions about homes in Minneapolis.
