Lisa Marie Brooks, a real estate agent, and her husband, Scott, a commercial airline pilot and builder, know potential: Together they've built or renovated 25 homes in three states, most of which they've resold. "This house actually had a lot of pros," says Lisa Marie of the 2,000-square-foot bungalow. "A pitched roof and a sunroom with lots of windows, plus great big oak trees all around." Now the fixer-upper is their home for good. Says Lisa Marie, "No chance we're selling this one anytime soon."
