The search for a home or a buyer is a very time-consuming process, especially without the aid of a real estate professional. Good real estate agents are proficient at sorting through available properties to find homes that meet your needs. Agents belong to an MLS (Multiple Listing Service), which lists available properties by numerous searchable characteristics - much more detailed and advanced than the public has access to. This will save you time as your agent can send you properties that specifically meet your needs so you're not looking at everything in the city.
gents have keys to all listed homes. Can you imagine calling every seller of homes you want to see, making an appointment and trying to be there when they are available to let you in? Or just getting into a few houses every Sunday during open houses? Instead, your buyer's agent will let you into many more houses at times that work with your schedule.
Experienced real estate agents are experts at negotiating the best sale/purchase price for your home. Efficient negotiation can mean signing a contract on your dream home vs. your second choice. Agents can also recommend ways to increase your chances in competitive bid situations and set expectations when they think odds are not in your favor.
