Despite a run up in home prices during the pandemic, San Antonio may end up being one of the nation’s coldest residential real estate markets this year, according to a recent report from online brokerage Zillow. San Antonio’s housing prices are expected to decline 2.1% by December, which would make it the second-coldest of the nation’s 50 top markets, according to Zillow’s report. That’s a significant change from last year, when the company ranked San Antonio as the country’s No. 13 hottest real estate market.
