South Carlsbad has an area called Aviara that is very nice, not far from the ocean, near the Bataquitos Lagoon and not too far from the I5 freeway. Not sure how much you want to spend, but here are two sample homes for rent in there. I have seen others in that area renting from 2700-4000. I have family that actually live a block or two away from the second listing, on Mimosa and it is a very nice community. As proof, the Four Seasons Aviara is a 1/2 mile away, LaCosta Resort is about a mile down the road. In the event that you would consider public schools, you can’t go wrong with the elementary and middle schools that are a few blocks away either.
