Showing.....is one thing! Going to contract on and purchasing is another.
The issues you have pointed out are ones that often come out after an agent has further researched the subject property. It would be of much greater concern if this information was not revealed prior to submitting an offer.
It does seem like it is time not well spend......but the RE agent has invested probably more time!
REaltors who are in fact members of the national Association of REaltors are required to disclose material facts...things that if you knew them, would make a difference if you bought the property.
However, we are not held accountable for things that we do not know for a fact.
In most cases the ONLY person that will know if a certain issue exists with a property is the seller, and sellers
ARE required to disclose material facts. I would caution you to be more precise about who you ask what...
If they are aware of it, they have to disclose it by law, as teh seller if you are aware of it, you too would need to disclose this on your property information report. you could be held liable in teh future if teh new buyer finds out and suffers a financial loss due to your not disclosing this.
Usually as a buyer's agent we aren't aware of lack of permits until we get a seller's disclosure. If you are talking about the listing agent showing you a home, they are representing the seller not you and again unless you are making an offer it is not necessary to disclose up front, however, if you asked them they would tell you if they had the knowledge (sometimes sellers "forget" they didn't get a permit).
Hi E. I agree with Mack if they don't know about it. But in most states, real estate agents are required by law to disclose any material deficiencies that will affect the price of the home, if they do know about it.
