There are about 1 dozen active builders in East Phoenix area ... Of these the most active are a couple of private builders, Fulton Homes, Shea, Blandford. Of the public builders Meritage seems the busiest ( I think they have unique insight to this market as they are based in Scottsdale ). Pulte seems to be purposely holding back on lot releases and specs .... Fulton seems to be building many specs. The market here is a little skewed due the presence of snowbirds (especially Canadians) near the summer end ... so specs need to be ready for them.
SPF seems to control a lot of land here but they seem to be just sitting on finished lots (not building much).... I'm thinking that their recent offering might bring the necessary capital to finish projects such as Charleston Estates in Queen Creek.
