Obviously, all the people saying "yes you need to get an agent" are agents. I have bought houses on several occasions directly through the seller's agent. Even though they clain to be working for the seller, they are working for themselves. No sale, no commission. If they get the sale, they get double commission.
So if they get a sale at $100,000 below listing price, the seller's agent still gets way more money than if the buyer has his own agent. You can work this to your advantage. The whole playing field is tilted in favor of the buyer right now, and the seller's agent will do whatever they can to help you buy that property, no matter what anyone says. Including dropping commission to get a deal done. That will never happen if you have two agents involved.
So if you've found a property you like, don't hand the transaction (and commission) to a buyer's agent. They're just taking your money, you don't need them, you already found the house on your own
