New rules could reshape homebuying. Here’s what it means for you.

Change is coming for the U.S. real estate sector, with implications for anyone buying or selling a home.

In March the National Association of Realtors agreed to settle litigation that had accused it of artificially inflating real estate commissions, which for decades have been between 5 and 6 percent of the sale price, paid by the home seller. The NAR denies the allegations but agreed to pay $418 million to settle several cases.

It also agreed to important rule changes that advocates hope will break the industry’s grip and give consumers more control over real estate deals — including how much they pay to agents and brokers. Experts believe the rule changes, which take effect Saturday, could alter how homes are bought and sold, decrease the cost of buying a home and possibly spur an exodus of Realtors.
