I'm a South Pas resident. Do you children? There are 3 public elementary schools in the city, 1 middle school and 1 high school. Admissions to the elementary schools is based on the geographic location of your residence. All 3 elementary schools are excellent but I would daresay that most parents would want their kids to attend Marengo, then Monterey Hills, then Arroyo Vista. You need to find a rental in the geographic area served by the school you want your kids to attend. If your kids are in middle or high school it doesn't matter where you live in the city.
The value of the homes, and the cost of renting also varies with the location of the home to the elementary school district. The home prices and rents in the Marengo district are higher than the Arroyo Vista district.
The city is very walkable, but some locations are much more convenient than others so I would suggest you look at the property before signing the lease.
I don't think you'll find too many 2-br townhomes or homes for $2k/mo in South Pas. The rents are high because of the excellent schools.
