Inspectors are people and they do make mistakes. First I'd call/email that inspector to express sellers concerns or explanation, I'd CC another agent on that too. 

Are there supporting photos ? If it's a material fact - yes it must be disclosed now.

I would disclose both even though it was only an observation by the inspector. Makes the seller look like he's right on top of it by hiring the specialist.

I would disclose the finding and the follow-up eval by the specialist

Disclose, disclose, disclose. Better to disclose the info from the inspector along with the follow-up by the specialist than to withhold either or both bits of information.

I don't think there can be "too much disclosure" in terms of Seller-CYA. 

Tricky question. A third opinion might work, but the issue of disclosure is open. The observation of an inspector is not concrete fact!

Yes, if both findings are based on facts and not on assumptions. The situation coud've changed since the "specialist" had made his inspection.

I don't think that "disclose" is the right word.

If the inspector finds issues where the seller thinks there are none, the seller certainly have the right to dispute the findings, but what is there to "disclose" when the inspector already stated the problem?

 Home inspectors act is generalists. If the specialist says something different, then you have to go with their opinion.

Yes, we should always disclose the inspection by a specialist.

Tony and Suzanne Marriott, Associate Brokers - any such disclosure helps bridge  the gap between what buyers hear from the home inspector and what sellers have to share.

Always a good idea to share.

Yes.  I would disclose that, especially if it helps your case!  I've seen many inspectors that don't know their arse from a hole in the ground and call out stuff that isn't an issue.

If a licensed specialist, electrician, HVAC, etc. has proven the observation false, I educate the seller to provide the correct information and then realize it is also best to disclose the observation.

Absolutely yes as long as seller has reliable documentation to substantiate his argument 

In Oklahoma, all recommendations by an inspector are subject to agreement with licensed and bonded contractors.

Sellers have the right to dispute the results of an inspection by hiring another qualified expert.  If the disagreement still exists between the two experts a mutually agreed upon third expert can be hired to resolve the differences.  (Florida procedure)

Yes.

Yes! We had an inspection that mentioned an issue with the foundation not being to code. Our building department  gave us signed copies of the permits and verification that it was up to code. Problem solved. 

yes they should if it was via a specialist....

Of course in the inspection response.

In Minn ,  seller still obligated to disclose anything the inspector does not see

Always. As if a problem is disclosed it would have to be disclosed in the Property disclosure.

Yes, it should be disclosed.  Transparency works.  A

Yes, you SHOULD disclose the greater authority, i.e. the specialist.

 Add inspector to 'The List."

If it is a concern the sellers need to provide additional work receipts that observation is not no longer an issue. They need to know this can become grounds to walk away from a home purchase. 

Great question Tony and Suzanne Marriott, Associate Brokers and I'd say that if an inspector made a claim about my home I believed as false I would NOT disclose his allegation.

It is knowledge now so yes.

Best to get those things out there so that they will not come back as a problem later.
