Rules that helped set real estate agent commissions are changing. Here's what you need to know

The cost of hiring a real estate agent to buy or sell a home may soon change, along with decades-old rules that have helped determine broker commissions.

The policy changes could help spur price competition for agents' services and lower the cost for sellers who now typically cover the commission for the buyer's agent, as well as that of their own.

In turn, more homebuyers could face pressure to pay for their agent's commission out of pocket. That could be a challenge, especially for buyers already stretching financially to make a down payment and cover other upfront costs involved in buying a home.

Still, housing market watchers say it can't be immediately determined how significantly any changes that potentially shift the cost of hiring an agent to a homebuyer will affect home sales. An adjustment period is likely as buyers, sellers and agents figure out how to navigate what comes next.
