It’s no secret that it’s tough to find an cheap apartment in Houston’s in-demand Inner Loop neighborhoods. But recent data shows rents in some of Houston’s outlying neighborhoods are rising at some of the highest levels over the last 12 months in the region.

Rents rose 8 percent overall in the greater Houston market over the last 12 months as of July, according to data collected by Houston-based Apartment Data Services. Bruce McClenny, president of Apartment Data Services, which collects data for apartment complexes in Houston, previously told the Chronicle that the traditional growth rate in rents is roughly 3 percent.

Here is a breakdown of some of top rising rents in each sub-market for the last 12 months:

Central: Heights, 9.5 percent increase

Northeast: Greenspoint, 9.2 percent increase

Northwest: Tomball/Far Northwest, 14.1 percent increase

Southeast: Gulfgate/Almeda Mall, 8.1 percent increase

Southwest: West Memorial/Briar Forest, 14. 4 percent increase
