"The housing opportunity index in Greater Phoenix was 66.4% in the second quarter. This compares to 76.2% a year ago (see charts below). A combination of higher interest rates and higher housing prices caused affordability to decline somewhat."
So I went to the National Association of Homebuilders website. Downloaded the spreadsheet and found Yuma was 77.5, Tucson, 76.9 and Phoenix is indeed 66.4. I will always think that living in the SW is great in Arizona when you see the rest of the spreadsheet. We are a bargain compared to California. No complaints here.
