In the latest weekly report from chief economist Michelle Meyer, the bank warned that "the housing market is no longer a tailwind for the economy but rather a headwind."

"Call your realtor," the BofA note proclaimed: "We are calling it: existing home sales have peaked."

BofA's economists believe the peak was seen when existing home sales hit 5.72 million, back in November 2017. From this point on, sales should trend sideways, as this moment in time is comparable to the rate the economy witnessed in the early 2000s before the bubble inflated.
