Check out Pacific Ridge school in Carlsbad also. It’s newer and I’ve heard great things from friends who send their kids there. They brought in the headmaster from Horace Mann to run things. It’s very small and individualized. Probably a bit pricier but you will save on housing.
You will get a lot more for your money housewise while still being in a great coastal community with one of the best public school systems in the county as well.
