History will note that, for a time anyway, local home renovation experts Chip and Joanna Gaines gave Waco something it has long sought: status as a destination point. Through the charisma, ability and resourcefulness showcased on their popular, Emmy-nominated HGTV show “Fixer Upper,” the Gaineses have drawn to Waco waves of tourists eager to track down the homes they’ve overhauled and to shop at the mecca that is Magnolia Market at the Silos. The couple is even credited with revitalizing home sales in the Waco area. The home-marketing site Realtor.com reports all 10 of the top home-search locations in the nation last year were in Texas — with the 76712 ZIP code in Woodway topping the list. And the 76710, 76711 and 76707 ZIP codes in Waco came in at two, three and four.
