As home builders try to gain more business, more will be going after the entry-level buyer, real estate expert Bradley Hunter told CNBC Wednesday.

"It's been hard to do up until now because the builders are saying 'the profit margins are so good in that move-up segment of market, I'm going to do move up. I'm not even going to mess with entry level,'" said Hunter, chief economist with Metrostudy, which provides real estate research and analysis.
