OK, I was born and raised in PHX. Actually, I grew up on a farm in Laveen!

It was very different there when I was a kid.
I would stay away from anything on the west side of PHX, no matter how far north you go. The dividing line seems to be I-17, but lately, that includes west of SR 51.
Be careful where you go in Central PHX. If you are not homosexual, I would stay away from between 7th Street to 7th Avenue, from McDowell Road to about Camelback Road.
It depends on how far you want your commute to be to work. I live in Chandler, right on the border of Gilbert. I am about 20 miles from the airport. In off hours, it would take me about 20 minutes to get to Sky Harbor.
In my neighborhood, you cannot touch a house here below $160,000. My current house is about 1400 sq feet and is about 17 years old. The newer homes in Gilbert, just across the road from me, are going for about $225,000 to $425,000.
I am searching houses out in the Queen Creek area. The particular home I am looking at is about 2300 sq ft. and is going for about $162,000. I have a lot of equity in my current house, so I will be able to put a good chunk down, and carry a smaller mortgage. It is about 10 miles from the new freeway, which should be done is about 2-3 years. I would say you would be about 40 miles from the airport out there.
If anyone needs a real estate agent or a mortgage specialist who works with all kinds of brokers, PM me and I will give you names for both.
The comments about getting a north/south exposure are dead on. Also, the comment about getting a tile roof is also correct.
One thing my dad always taught me was to live EAST of where you work so that when you go to work in the morning, the sun is behind you, as well as when you are driving home. Does not always apply to the airline business because of the odd hours, but something to think about.
I will also be more than happy to provide anyone with the names of good doctors, dentists and pediatricians for those who have kids.
Also, make sure you drive about 2 miles north, south, east and west of where you look for a house. When I bought my current house 13 years ago, I had no idea that 2 miles south of me was a very bad area. It has never caused a problem for me, but just be aware because the zoning laws here do not exist.
Anyway, just my thoughts on this, let me know if you have any other questions.
