I feel for you JHurt. I think we bought the 2nd Money Pit ever sold. Our's turned out to have been started as an old hunter's cabin. After 6 or 8 'add-on's' it ended up being what was sold as a Fine 2900 sqft Country Home. Yeah, right.
We find weekly surprises such as light switches that go nowhere, roofs with no shingles, metal roofs that mysteriously starts leaking, chimney's that aren't sealed, rooms with no HVAC outlets nor electric outlets. Thanks to all of those and more surprises goes to the "inspector" that turned out to be the realtors son. His General Contractor License turned out to be a Driver's License - for real! His insurance turned out be be a bare minimum Liability Insurance policy for his pickup.
Let it be said, there are many downfalls to having to remotely buy a place based on published realtor's info. Not everybody tells the truth, or at best fails to disclose anything negative. Sure, we hate the problems, but on the other hand, we love the place. Located near a little town of 480, near a state medical center, and whoopee - only one signal light in town. We've grown calloused to surprises, and are continually developing handy-man skills. The good outweighs the bad, by far.
We view our stream of problems to that of buying a new vehicle. You buy it hoping for zero problems. But that's just not how it goes. Hang in there - eventually the problems such as your sewer system will fade into distant memories, replaced by new problems to resolve.
