Why would you ask a question at an auction that could potentially put other buyers off if you had no intention of bidding? Couldn't you have gone up to the agent before or even after the auction?
I agree with you regarding the agent disclosing to the buyer that there is an easement or overlay etc that would effect the purpose for which the buyer is purchasing the property although the onus is on the buyer.
I only believe that the information should be given though if deemed...
It's an easement! Do you expect the agent to tell you upon entering the front door if a property has - an easement, an overlay etc, an outstanding power bill?
When does the onus fall on the buyer to make sure that they have done their own research?
I would have thought that if you're buying the house the information you require would be in the required documentation and that you wouldn't rely on the agent for your due diligence. Last time I checked the agent represents the seller not the purchaser. If the agent lied to you then I agree...
