These days more civilised liao.There was a tip I heard from one of the forumers here, but not sure how true.
It was mentioned that the chances of success in purchasing resale is higher if you do not use a buyer agent, so the seller agent does not need to co-broke (share comms) and will tend to recommend your offer to the seller.
Anyway good luck!
Back in the day 10+ years ago when COV was the rage. I wanted to get this Tiong Bahru hdb. Gave cheque liao. But agent chu pattern, said i have to pay buyer agent fee of 1% and must be with this female agent. I found out she's the wife of the seller agent and is heavily pregnant. I said no go and he actually came down and returned me the cheque.
I buay song next day went to the hdb to look for the owner wanting to tell the owner her agent is screwing with her. When i reached there, the agent was sitting outside the door like dua peh kong guarding the place. Who knows how long he has been sitting there. Crazy fella.
Decided to move on in the end.
