I now know of four buyer-units who shortly after taking ownership have been surprised by issues of baroque sewer-line setup, longtime neglect of sewer issues on the part of the previous owners, and/or lack of candor on the part of real estate agents regarding same, hence very non-negligible expenses associated with putting the situation right. So obviously the smart thing to do is pony up the extra few hundred in advance for a sewer inspection to ensure that things in this department will not hit the fan in the near future.
But I understand there is also a plumbing inspection that is separate from the sewer inspection that can identify issues the sewer inspection might miss? And that one can get a roof inspection separate from the general structural inspection? How many inspections should the cautious post-bubble buyer with time on her side be looking at? This is all hypothetical, but let's assume that the house in question is a sturdy house with a basement built prior to 1940, with standard workmanship and materials for its period. Thanks for any advice or cautions.
