That is why I asked about agency. Traditional Long Island Real Estate was always done where the agents/and brokers work for the seller in a client relationship. That means for those who do not know, the buyer is a customer.
It's the job of both agents to work in the best interest of the seller and if they didnt, the seller could actually have a legitimate lawsuit.
This means anything and everything they can find out about a buyer that puts the seller in the best possible position for the highest price is the law (client relationship) All information and discussions with the buyer that would help the seller is to be disclosed.
The buyer is the customer and is owed nothing except honesty and cannot offer to the buyer any information about the seller that would put the seller at a disadvantage and that means almost anything, except a buyer could ask if there was a murder in a house, they would have to answer honestly and of course they could not cover up defects as that is called fraud..
At the time of the offer, preferably at first meeting this was disclosed to your friend, however, I haven't been back on Long Island in gosh almost 16 years now, when I left things were changing and I was involved in that change to represent buyers as clients is all I will say.
Typically I always worked in a client relationship which meant my main business was only with sellers except when a buyer contacted me about buying one of my clients homes, it is an agent duty to inform them, educate them and have them sign off on exactly what being a buyer customer means VS a buyer client.
I think I know about what town you were in, being close to anything labeled New York City, meaning Queens, was a zoo. True, agents there ignored all proper procedures, I used to in some cases defend my sellers in Nassau county from their tactics. But that is due to lack of enforcement.
