Disclosure of past inspections on a home is up to the home seller. If the listing agent is aware of any past inspections, they also have an obligation to disclose that information. In the case where the buyer had an inspection done, then cancelled the purchase, that seller must disclose what they know about the results of the inspection. This is pretty straight forward in the case of a Standard Sale or an Equity Seller. Both the Seller and the Listing Agent have to disclosue material facts that may impact the property.
In the case of a Bank Owned or REO property, the seller is exempt from disclosure since they have never lived in the home and have no disclosures from the previous owner. However, I've been in several situations lately where, during escrow, the buyer's inspection reported and active slab leak and the presence of mold. Even though that buyer eventually cancelled the purchase, and even though the bank is exempt from disclosure, the listing agent is obligated to disclose this information to any subsequent buyers.
While past inspections and reports may help you determine the condition of the home, I would always recommend hiring a reputable, experienced inspector to conduct a thorough inspection, including a mold inspection, and review the resuts along with any previous reports proviced by the seller or the listing agent.
Finally, there is no "forum" for home inspections. The reports are not registered, posted, or tracked by any governing board. They are the property of the person who commissioned the inspection.
Hope this helps!
