Redfin chief economist Daryl Fairweather joins Wealth! to break down the new rules about buyer-broker agreements from the National Association of Realtors.

"It used to be that if you were a buyer, you didn't really have to pay a lot of attention to how your agent is paid. The seller would pay the buyer's agent. But now, buyers are paying the buyer's agent directly, and they need to set a contract at that first tour, or at least sign something that outlines how their arrangement is going to go," Fairweather tells Yahoo Finance.

She explains that this new rule is keeping some homebuyers on the sidelines as they are intimidated by the agreement. However, as it becomes more normalized, it won't become "that big of an impedance."

As low inventory has caused the housing market's affordability crisis, Fairweather notes, "It's going to take years and years of building new homes to get to a place where we have sustainable affordability."
