Lots of ways to find a buyer’s agent, which is probably what you meant.

Ask your friends who they used to purchase a house.

Check online/yellow pages for realty agencies near where you want to purchase a home. Call them up and inquire, or better yet, visit the agency and ask questions about the procedures in buying a home.

Read reviews on possible agencies/specific agents.

Don’t pick the first one you see - interview several and then make your choice.
