When millennials buy, they're leapfrogging past the traditional, smaller starter home. This younger generation paid a median of $217,000 for a 1,800-square-foot house. That median is nearly identical to what older generations buy.

Across the United States, the typical home costs $222,000, has three bedrooms, 2½ baths and 1,900 square feet. For someone with children at home, that figure swells to 2,000 square feet and a median price of $234,000.
