Gr8ful1,
I've lived in a few different places in town. Originally I was in a 1996 Richmond American home located in Continental Ranch, west of I-10 on Cortaro Road. Home was great quality, I've heard some homeowners had roof issues but I think that was another builder. The area was just coming up around then and I had a great time living there. Now it is a bit more congested but there is plenty of shopping and entertainment popping up. When they fiiiiiinally get the Twin Peaks/Linda Vista interchange done that will help expand the area even more.
I currently live in a Pulte home up in
Gladden Farms and I like it even more! Pulte has a pretty good reputation for building a quality home also, just do a search on Google and see what you get. The area is a bit further out (west of I-10 between Tangerine and Marana exits) but is coming along nicely. There are walking trails and parks, and careful attention is paid to the landscaping. They are completing a new Tangerine interchange and Fry's shopping center by next Spring and that should be nice when done.
Hope this helps!
