The Castille Homes of Mission Viejo are also very popular. They are slightly newer than the La Paz homes. The Mission Viejo Company built these in a few different areas of Mission Viejo. There could be slight differences from one area to another. There are single level floor plans and two-story floor plans. I have seen many of these homes that have been expanded and nicely updated over the years. Wonderful proeprties near parks and schools and shopping. People tend to stay in these homes and not sell for many, many years! Who can blame them?
