The cost of rent in San Antonio has dropped nearly 3% from 12 months ago, rental marketplace Zumper revealed in its annual National Rent Report. The average cost of a one-bedroom apartment in San Antonio declined 2.8% in the past 12 months to $1,050, making the Alamo City the fourth most affordable major housing market in Texas, according to the study, released last week. Even so, SA’s rental cost decline is far less impressive than that of other, more expensive Texas markets in the past 12 months. The average cost of a one-bedroom apartment in Fort Worth dropped 10.2% to $1,230, for example, making it the most significant price decline of the 100 markets covered in the report.
