It wasn't supposed to take long for the Trump tax cuts to hobble housing prices, particularly in the high-tax, high-cost metro areas where the new law was poised to rip federal incentives to buy new homes.

Nearly nine months later, those warnings have not materialized. While the nation's housing market is showing signs of weakness on several fronts — particularly in new-home construction — prices across the country are continuing to climb. That's true even in the million-dollar-plus markets of California and Washington, D.C., which appeared most at risk for a hit when the bill was pending.
