Title V does mean that the system has passed current standards, but you should take the time to review the inspection, understand the system in place, and evaluate it, using local experts where necessary. You wouldn't buy a house without knowing if the roof is in good shape or not, and a septic system works the same way. Unlike a roof though, you can't "see" it, and I think it's this unknown quality of septic that gives buyers pause. It's an important - and expensive - system for you house, so you should carefully evaluate it. It's not necessarily straightforward either - "old" is not necessarily "bad" and "new" is not necessarily "good", although I have found that some people are quick to race to those determinations.
