The climate in Vista has to be the best in the world as it is past the fog layer and cooler weather of the coast, but just shy of the hotter temps in Escondido and parts of San Marcos. I moved from Carlsbad to Vista to San Marcos, and the weather in Vista was the best.
There is a neighborhood called California Summit that is located directly across from the new Home Depot off of Melrose and is the first neighborhood you hit when you enter Vista from the new Melrose extension. No HOA, no mello-roos, and it ‘officially’ is not Shadowridge. A commute from there to the 5 is 1 minute slower than a commute from Bressi Ranch. You take Melrose 1 mile to Palomar Airport Rd and head west. No 78 involved. An 1800 sqft. home with a big yard built in 1994 is listed there for 529 right now. I bet they’d take high 400s in this market.
