However, I am glad you decided on Carlsbad though. I think that would be the best bet, as prices are very affordable right now compared to a couple years ago, plus the schools are much better than San Marcos.
La Costa Ridge is a beautiful gated community and there are just a few new homes left ( the last time I checked) you can also check out my site http://www.CarlsbadNeighborhoods.com or this link containing current homes for sale in La Costa Ridge
I would love to help you as your buyers agent. and I could help show you new or resale homes around Carlsbad. Please give me a shout or email me direct at email@example.com

San Marcos has some very nice communities. San Elijo as mentioned, There is Twin Oaks Valley, Its your part of country close to the city. Prices range from 350000-1000000. THe Hoa fees are under 100 in most areas. If you are looking for mountain views and valley breezes this is a terrific area. I have a listing on 1acre with pool 5 bedrooms very country for $599,000.
The other nice are is Discovery Hills lots are somewhat small and it seems as houses are very close together as opposed to Twin Oaks Valley. There are several older homes in San Marcos as well in the Woodland Parkway area. I have lived in San Marcos for 20 years.
There are many nice areas in San Marcos. It all depends on the price range you are interested in. My top choice for you is where I live and work in San Elijo Hills. This is an amazing home town community with all the perks, ie parks, schools, shopping and offers some of the best ocean view homes in San Diego. There are condos, townhomes, single family homes, including gated communities and luxury estate homes. My next choices are Discovery Hills, Lake San Marcos and then Santa Fe Hills. These are more "cookie cutter home communities". I would love to help answer any quesitons about San Marcos, or any of the surrounding communities and or cities.
