Yeah, I would agree that even if the buyers had an inspection done, if there were no signs of active water penetration (puddled, saturated or freshly stained boxed, etc.) at the time of the inspection, the inspector may have had no reason to report active water entry but only evidence of past water entry, monitor, and further question the sellers. We've all had this same situation and reported this way, hopefully without buyers like this suing everyone. Tort reform is needed and people filing these frivalous lawsuits need to re-imburse the defendants' costs if they lose the case. Our pre-inspection agreements are worth little not matter how strongly they are worded. Reporting what you see and careful wording in your report and a lot of CYA can help keep inspectors out of court.
