Please help me what are some of the advantages of going with Realty Company instead of house searching myself?
You aren’t hiring a realty company; you’re hiring a specific buyer’s agent. Most homes for sale are listed with a seller’s agent. The seller’s agent is working for the seller so they can’t actually advise you in any way.
Don’t get sucked in by agents who are willing to do dual agency. This means they claim to be working for both sides, so they’ll advise their seller and they’ll advise you, but they aren’t supposed to share with the seller what you say and vice versa. I don’t know any agents who are willing to do this out of fear of being sued if they slip up and share information they aren’t supposed to.
Without an exclusive buyer’s agent, you’ll have no one to help you gather data on what would be a fair price for the home you like, no one to explain the seller’s duties to you, and no one to advise you as you during the negotiating process. Above all, the seller’s agent will pocket the money meant for your buyer’s agent but won’t do a damn thing for you. Not hiring a buyer’s agent is like throwing away money.
