I agree, those are the tippy-top schools and will be reaches for OOS students. But OP has a 1550 SAT, 4.0 UW GPA, all 5s on APs, and has developed numerous apps that have been recognized by the U.S. House of Reps and IBM, is an Eagle Scout, and has other very good ECs. I’m not saying those schools are a shoo-in, but this kid definitely has a shot, and their cost is significantly lower than some the original schools under consideration. I stand by my recommendation to the OP of these schools as reaches to shoot for.
