Joseph Beben wasn’t in the market for a house until he heard about a year-old community in suburban Phoenix where 10 homebuilders are offering buyers incentives such as swimming pools, built-in barbecues and subsidized mortgage rates.

Beben, a 33-year-old general manager at Best Buy Co., visited three of the sales offices flanking the main corridor of The Bridges at Gilbert, whose 17 subdivisions are among the about 200 locally that have opened since early last year. He settled on Woodside Homes’ community within The Bridges after the builder agreed to cover as much as $10,000 of his closing costs, and throw in another extra he liked.
