Zillow Case-Shiller House Price Forecast: "Reaccelerating" in January

The Case-Shiller house price indexes for December were released this week. Zillow forecasts Case-Shiller a month early, and I like to check the Zillow forecasts since they have been pretty close.

From Zillow Research: December Case-Shiller Results & Forecast: Reaccelerating

Monthly growth in January as reported by Case-Shiller is expected to accelerate from December in the 20-city and national indices, and slow in the 10-city index. The pace of annual growth is expected to climb in all three indices. S&P Dow Jones Indices is expected to release data for the January S&P CoreLogic Case-Shiller Indices on Tuesday, March 29.
emphasis added

The Zillow forecast is for the year-over-year change for the Case-Shiller National index to be at 18.9% in January, up from 18.8% in December.
