Multi-generation home buying a Bay Area, national trend

While it has been a cultural norm among some to see multiple generations sharing a home, home buying habits are reflecting a trend toward Millennials from a wider cross-section of the community doing the same-- and the reason is financial.

The trend is not only a Silicon Valley one, but also a national trend. More and more, houses-- especially larger ones-- are being purchased to be shared by a multi-generational family.

The National Association of Realtors has been tracking the trend.

The largest number of multi-generational home buyers are 39 to 53-years-old-- people who identify as older Gen Y's and Millennials. Three out of four are blending their households to care of aging parents, or because their adult children are moving back home, or because those adults children never left home.

Real estate agent Mark Wong says more bedrooms are needed. He's with the Saratoga office of Alain Pinel Realtors.

"At least three bedrooms, four or five," he says. "That's why people love to buy the house and then they remodel, expand it to what they need."

Wong recently sold a three bedroom house, listed at $999,000. It's going to be expanded for a multi-generational family.

"The lucky buyers already engaging different contractors to come in to do measurements, planning," Wong said, as he pointed toward a patio area off the living room. "They probably can move this out, add one or two bedrooms here, or they can even build a two-story house to fit their needs. There's lots of potential here."
