The document summarizes the real estate market effects of the new US tax bill. It notes that home sales in San Francisco plummeted 49.3% year-over-year in December while prices rose 31.7% for homes and 7.9% for condos. The tax bill eliminates or caps popular deductions for mortgage interest, property/income taxes which will significantly impact Bay Area homeowners who pay high taxes. The effects of fewer deductions on housing demand and prices are uncertain but the market will be closely watched.
