I agree that it stands to be difficult.
There really is nothing more important for a prospective buyer than a pre-purchase inspection of the property. The inspection might not turn up all hidden defects but the inspection can indicate whether the buyer should be concerned about any hidden/undisclosed defects.gh
One house we looked at seemed great until an inspection revealed dangerous he electrical wiring issues that would have required complete (and immediate) whole-house re-wiring. Our inspector informed the homeowner of the fire danger he faced if repairs were not made. We did not purchase the house.
Fire danger? The entire electrical system?
Inspectors tend to not truly understand the issue when it comes to electrical concerns. I have rarely seen a home that required a complete re wire. Most of the time the wiring within the walls is just fine although rewiring does provide some benefit.
The source of almost all electrical fires is at the electrical panel or at receptacles. Most of all of those issues at either of those can be remedied without replacing the wiring within the walls.
Those not starting at those places are often caused by issues at one of those places mentioned, with most being due to issues at the electrical panel.
More often than not I have seen an inspector miss issues that should have been discovered. Most inspection services provide a very lightweight inspection that does little to discover issues. In one particular situstion I was visiting a friend in a recently purchased home. As I walked past the electrical panel I heard buzzing. Immediately upon opening the panel door I saw electrical code violations of improper breakers being used. Only “listed” breakers can be used in any given panel. In most cases that means name brand breakers matching name brand panels. I happened to know some of the breakers in place were not listed to be used in that panel and as such, were a code violation. Upon further inspection I discovered the buss (the metal bar the breakers connect to) were burned due to arcing (the buzzing I heard). The entire panel needed to be replaced but the “inspector” indicated the electrical system was in good and unremarkable condition.
I have seen plumbing issues that anybody would have questioned missed or ignored by “inspectors”
I don’t have a lot of faith in inspectors in general. Having worked in the real estate field, I have seen way too many issues not raised on their reports.
It’s a failing in the real estate industry that appears to go without remedy for at least 4 decades I’m aware of.
