The opinion of homebuyers’ children has a big sway in real estate decisions, a new survey finds. Fifty-five percent of homeowners surveyed say that their children under the age of 18 have an opinion on which home to buy, according to a new Harris Poll Survey commissioned by SunTrust Mortgage of more than 2,000 adults.Seventy-four percent of millennial parents between the ages of 18 and 36 report their kids have even more of an influence. And 83 percent of renters said the opinion of their children will be a factor in which home to buy, the survey finds.The top requests of children include their own bedrooms (57 percent); a large backyard (34 percent); proximity to parks and activities (25 percent), close to schools (24 percent), close to friends (24 percent), and a swimming pool (21 percent).“As a parent of two kids, I know from experience that including children in the homebuying process is not only fun for the whole family but also educational for our home buyers of tomorrow,” says Todd Chamberlain, head of Mortgage Banking at SunTrust.
