We live close to the Dalcastle/Linda Heights area and have not had any ongoing crime problems. About 10 years ago, there was a significant hail storm and almost everyone in our neighborhood had their roofs replaced. We had a rash of daytime burglaries (including our home) and the police said it was probably the roofing crews. Have not had any other problems since then. I know people that live in several of the other areas you mentioned and they have never said they were concerned about safety.
I have been concerned about the surrounding areas and especially the retail near our home, but have not really had any issues yet. I personally would like to move to the North Garland area near Firewheel, and had begun looking when the economy went south. You mentioned Waterview, which is very nice and if your daughter is accepted to a magnet school, she would have bus service. Just wanted to let you know that Sachse is also in GISD and there is a community called Woodbridge that is similar to Waterview. You just have to be sure you are in the south part of Woodbridge, because the north part of Woodbridge is Wylie School District.
You don't mention how old your daughter is, so not sure how soon you need to worry about this, but one thing you might want to consider is High Schools. My sons have gone through the magnet program in GISD since Kindergarten and we have been very pleased. Unfortunately, the choice of school does not really work in High School. If you do not want to go to a magnet high school, then you cannot choose your High School, unless it is one of the less popular schools. When we bought our home, South Garland HS was our neighborhood school. It has really gone downhill in the past 10 years and was rated unacceptable last year. If your child wants to go to Rowlett HS or Sachse HS (generally the preferred schools right now) then you need to live in their transportation area, because they are not magnet schools. This is not necessarily the same as living in the city of Rowlett or Sachse. You must go to the GISD website and look at the transportation maps. The only problem is those can change. If your daughter wants to attend a magnet high school, then it doesn't matter where she lives except for travel time. Lakeview Centennial is becoming a popular school now, because they started a Collegiate program. Garland HS has the IB program but it is a very difficult program and usually only about 50 students graduate with the full IB program.
You can go to the City of Garland website to view crimes reported in various parts of Garland. Check out the Crime Reports Mapping option. The scariest thing is the number of Sex Offenders living nearby. https://www.garlandtx.gov/gov/lq/safety/police/reports_wa...
