My wife was a buyer’s agent for years. This is nothing new, just someone new jumping in on the real-estate market.
Some buyers agents are horrible and you’d do better with a sellers agent (who you also don’t have to pay, they are both paid for out of the listing agents commission).
Just know the market and what you’re getting into. The best thing you can do when buying a house is pay for your own home inspection and don’t use anyone the realtor (or buying agent) recommends!
