Realistically for that kind of space I’d be looking at the area East of El Camino Real in Encinitas. Seems you can find a little more breathing room. Sometimes I see a good rental pop up in Cardiff, but they go fast. Since schools are not a primary concern, you could consider the area east of El Camino Real and south of Encinitas Blvd. and then you have the Manchester Ave. entrance to I-5.
